How to truly make MEMS technology “everywhere”

The development of any science and technology is often ups and downs, with highs and lows. Technology needs time to prove, but also the accumulation of industry, MEMS technology is a technology that has experienced ups and downs. Since the 1970s, MEMS has evolved from sensor technology, gradually forming a micro-electromechanical system with an intelligent “brain”, and its application has gradually expanded from military to civilian use. Today, MEMS technology is “ubiquitous” , becoming a standard-grade semiconductor technology.

For the popularization and application of MEMS technology, Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, is very optimistic about its prospects. Because MEMS have good cost performance, high performance, low power consumption, and small size, the size of MEMS systems can be in millimeters or even micrometers and nanometers. These features are suitable for applications such as medical, industrial, automotive, aviation, and location services. At ADI China’s 25th Anniversary Media Technology Day, Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, explained ADI’s ubiquitous MEMS technology and the application trend of MEMS sensing technology. ADI’s MEMS products have been widely used. .

MEMS technology is “everywhere”

MEMS is a system that integrates microsensors, signal processing, integrated devices, and communications. MEMS accelerometers, microvibrators, MEMS optical sensors, pressure sensors, and gyroscopes all incorporate MEMS technology. Because MEMS is a comprehensive technology that integrates many disciplines such as electronics, optics, materials, mechanics, chemistry, and mechanics, there are many problems in the process of advancement. ADI’s strong technical strength and innovation are exactly these customers. key to the puzzle. Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, said that MEMS technology is ubiquitous, and we come into contact with many MEMS-related products every day. For example, there are many MEMS accelerators in mobile phones. Its function is to perform screen rotation processing. When entering the tunnel, MEMS technology can guide the car, and the airbag in the car also uses MEMS to control the body stability, etc., automatic driving, mobile phone positioning, vehicle supervision, precision agriculture, urban parking, surveying and mapping, airport platform, bridge monitoring , port loading and unloading, slope monitoring application scenarios are the most commonly used MEMS technology.

The MEMS system has a very important application in the national economy. With the advancement of intelligent products, MEMS also has its own advantages in intelligence. What are the advantages of ADI’s MEMS technology? In this regard, Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line Said that with the increasing demand for massive positioning, satellite navigation is inseparable from inertial navigation. my country’s Beidou satellites will complete the basic global layout in 2020, and domestic Beidou can be used to achieve high-precision location services. ADI’s technology will be more widely used, and inertial navigation is required to connect massive location needs to the network. Nowadays, the minimum navigation accuracy of Beidou is 2.5 to 5 meters. For many applications, such accuracy is far from enough. At this time, it is necessary to use the assistance of MEMS technology to improve the navigation accuracy of satellites. Satellite navigation is very practical, but it has an inherent disadvantage, that is, the signal passing through the troposphere has a refraction error. Such positioning accuracy is not accurate enough. For vehicle applications, such a large error is not allowed. When the car enters a tunnel or parking lot and the satellite signal is interrupted, the car can only use inertial navigation, which is MEMS technology.

Unmanned driving is one of the most popular applications at present, and driving positioning is a technology that must be configured for unmanned driving. In complex driving environments, MEMS technology and satellite navigation complement each other. MEMS inertial sensors include low-precision inertial sensors, intermediate-level inertial sensors, and high-precision inertial sensors, with different application scenarios. Unmanned vehicles generally use low-to-medium-level inertial sensors, which are characterized by high update frequency. The inertial sensor is a high-frequency sensor that detects acceleration and rotational motion. After processing the inertial sensor data, the displacement and rotation information of the vehicle can be obtained in real time. However, the inertial sensor itself also has problems such as deviation and noise that affect the results. Inertial sensors have sensors, signal conditioning, various temperature compensation calibrations, etc. ADI’s MEMS technology incorporates these things. In November 2019, ADI just released a device-scale inertial sensor. “What we want to do is high-precision positioning, and at the same time, we will do mass market. You may have requirements for this kind of cost-effectiveness. We hope that the performance will be good, and we will be able to provide long-term positioning and accuracy. Now we need small size and low cost. ADI’s S1650X series inertial The sensor is aimed at this market.” Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, told the media editor.

ADI has very good detection of gravitational waves, various ADCs, processors, and the company provides customers with a complete solution. ADI’s inertial sensor uses a core sensor, which has very good vibration suppression characteristics. For example, in a car, it can detect the rotation angle of the car and the deviation of the car’s heading. There are many ADI inertial sensors on agricultural drones. ADI uses a differential structure internally, which achieves very good vibration suppression characteristics, including applications such as drones, agricultural tractors, and automatic driving, which can reduce product bumps.

The current trend of sensors is smart sensors, and many sensors have many integrated smart nodes, which requires smaller, low-cost, low-power MEMS sensors, which are essential in machine physical examination, prediction, and information processing. of. To improve the measurement accuracy of the sensor, the sensor must be sensitive enough, and the noise density is very low. Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, mentioned that the current ADXL100X series has just achieved such a technological breakthrough. The frequency can reach 45KHz, the effective bandwidth can reach 30KHz, and the noise can reach 25dB, which is far ahead in the industry.

In bridge applications, MEMS sensors have very low frequencies, which are important for monitoring, and piezoelectric sensors are difficult to achieve. ADI has a very deep accumulation of system technology, which can integrate MEMS sensors into various signal conditioning, and provide a complete vibration solution to meet customer needs. Another application of MEMS sensors is earthquake early warning. In the past, earthquake monitoring equipment was arranged in low density. Now, big data is used to realize early warning. Using low-density professional seismic equipment and high-density auxiliary seismic equipment, early warning is achieved through MEMS accelerometers. Accelerometers must have low noise and low power consumption.

Earthquakes have different levels. The lower the level, the smaller the vibration amplitude. It is very intuitive that the vibration amplitude is small and there must be low enough noise to distinguish the small enough level. There are also a large number of spots that are powered by batteries. You don’t know when the earthquake will happen, you can only keep it working, so the sensor must have enough low power consumption. If these two are considered together, ADXL355 Definitely the first choice in the market. In the gas meter, it has been successfully applied by customers. When a strong earthquake of magnitude 5 is detected, the gas meter can be automatically cut off to prevent the occurrence of secondary disasters.

Finally, Zhao Yanhui, director of ADI’s Asia-Pacific MEMS product line, said that ADI is the first company in the industry to commercialize MEMS technology. It started in 1987. In 1991, it replaced the traditional bubble with MEMS. In 2019, ADI invented CLHP again. Inertial sensor. With the development of Beidou and 5G industries, a large number of location services will make ADI’s MEMS technology shine.

The specific scheme of artificial sensory nervous system based on memristor proposed by microelectronics

At present, human society is evolving from informatization to intelligence. An intelligent society requires an efficient and intelligent information perception system to effectively identify, process and make decisions on the huge amount of information perceived, and to effectively filter repetitive and meaningless information. Therefore, it will become an important development trend to construct an efficient intelligent information perception system with biological reality based on the functional characteristics of the biological sensory nervous system.

Recently, the team of Academician Liu Ming from the Key Laboratory of Microelectronics of the Institute of Microelectronics, Chinese Academy of Sciences has proposed an implementation scheme of an artificial sensory nervous system based on the habituation characteristics of memristors. Habitual spiking neural network for autonomous cruise obstacle avoidance.

The research team constructed a sensory neuron based on Mott memristors and sensors. The neuron can sense external analog signals and convert them into real-time dynamic pulse signals, realizing the basic function of sensing and transmitting external signals. The sensory neurons are further connected with the relay neurons through synaptic devices to construct the habituation perception system.

The synaptic device has the habituation evolution trend of the weight under continuous stimulation, which in turn affects the transmission efficiency of the sensory neuron signal to the relay neuron, so that the output of the relay neuron exhibits a frequency drop characteristic (that is, the habituation characteristic, as shown in Fig. a). Based on this habituation feature, the team further constructed a habituation spiking neural network to realize the robot obstacle avoidance function.

The test results show that the memristor-based artificial sensory neural system constructed based on habitual learning rules can effectively improve the robot’s obstacle avoidance efficiency.

The habituation sensory nervous system can also be applied to different perceptual systems, such as smell, taste, vision, hearing, etc., through different sensors. By realizing the perception system of biological reality, it is expected to realize a more biologically intelligent terminal system.

Zhong Nanshan’s team announced the pneumonia detection method: IgM detection test paper, constant temperature amplification chip

Recently, at the first multidisciplinary online forum on new coronary pneumonia, Academician Zhong Nanshan and his team shared the latest research results on the diagnosis of new coronary pneumonia: two detection methods for new coronavirus infection, namely rapid immunoglobulin M (IgM) detection. Test paper and constant temperature amplification chip.

Rapid immunoglobulin M (IgM) test strips

It is reported that the principle of the detection is mainly realized by lateral flow immunochromatography. IgM refers to the immunoglobulin M in serum. It is the first immunoglobulin produced by the human body after exposure to the virus. It is an important indicator of acute or recent virus infection. Generally, it occurs on the 7th day of infection or 3-4 days after the onset of the disease. Symptoms can be detected.

The advantages of this test are: 1. The sampling is simple, and only 0.5 ml of blood sample (serum, plasma, and whole blood can be used) can complete the test; 2. The time for antibody detection results is shorter, which greatly improves the detection time. Efficiency; 3. The detection is convenient, and some grassroots hospitals and medical institutions can also conduct the detection.

Constant temperature amplification chip detection method

In contrast, the constant temperature amplification chip detection method can also be used as an important means to identify the current new coronary pneumonia and influenza in addition to the detection of new coronavirus infection.

According to Academician Zhong Nanshan, the test only needs to be completely broken with the buffer, and then loaded. The biggest advantage of the constant temperature amplification chip detection method is that it can detect multiple patients simultaneously, and distinguish the new coronavirus from influenza A and B, as well as other existing viruses, which plays a very important role in the investigation of suspected cases. .

Nowadays, smart wearable products have become an indispensable part of our daily life. Products such as earphones, smart watches, bracelets, and smart glasses have become a must for modern people. In September 2014, Apple launched its first smartwatch. Since then, Apple has lifted the curtain of smart wear in the market, and many companies such as Amazon, Samsung, Huawei, OPPO, vivo, etc. have all been involved in the wave caused by smart wear.

From IDC’s research reports on smart wearable shipments in 2015, 2016, 2019 and 2020, it can be seen that the shipments of smart wearable devices are increasing year by year. Several major manufacturers in 2015 and 2016 include: Xiaomi (37.4% market share), Little Talent (7.4% market share), Lexin and Huawei (5.4% and 5.1%) and Apple (3.4%). In 2020, the main manufacturers of the smart wearable market have undergone a big change. From the above-mentioned manufacturers, it has become a major manufacturer of mobile phone manufacturers, such as Huawei, Xiaomi, OPPO, Apple and BBK. At the same time, in terms of share, it is no longer the dominant situation of Xiaomi. After various mobile phone manufacturers joined the smart wearable market, the situation has become a multi-polar trend. Every mobile phone manufacturer regards smart wear as an important part of the ecological environment of its own products. Take Huawei’s wearable devices as an example. In the fourth quarter of 2015, Huawei’s shipments were only 639,000 units. In the same quarter of 2019, its shipments soared to 6,182 thousand units. By 2020, shipments of wearable devices will still grow slightly, reaching 6,761,000 units. It can be seen that the smart wearable market still has great development potential, and more and more different companies have joined this market to compete for share.

The most important point in developing different new products is how to catch the eyes of customers, and the products need to be able to meet their needs. With the development of science and technology, health has always been a topic of concern to everyone. How to check their own health status in a timely manner will be a focus for customers in the future, and it is also one of the selling points that products need to have. Instead of going to the hospital for regular physical examinations, customers want to know their own situation in a simple way. Therefore, if it is a smartwatch that can integrate sleep monitoring, motion detection, and even support biosignal detection, such as electrocardiogram (ECG), photoplethysmography (PPG), bioimpedance (BIO-Z) measurement, etc. So can this product attract customers to buy it? The answer is yes. Therefore, integrating different health detection functions has gradually become the mainstream trend of smart wearable products. Because this type of smart wearable product or portable health monitor is completely unlike traditional medical equipment (especially in terms of product size and measurement accuracy). Therefore, we call it “new health monitoring products”.

The human body has many types of physiological signals, such as the PPG and ECG just mentioned, what do they represent? ECG, also known as electrocardiogram, can diagnose various heart diseases and abnormal states by measuring electrical signals in the body. In contrast, PPG uses the light transmitter of new health products to generate specific wavelengths of absorbed light that penetrates the skin and blood of the human body, and is reflected to the receiver, where the light signal is converted into an electrical signal by conversion in the product. Information about blood pressure and blood flow in the human body. Finally, customers can see relevant data through portable monitoring products such as smart watches and wristbands.

Figure 3: Simplified PPG detection process

It can be seen that in order to meet the multi-application and multi-channel requirements of new health monitoring products, AFE products need to be able to support multi-application scenarios and multi-channel requirements. In addition, since physiological signals are relatively weak in the body and are easily interfered by the outside world, AFE also needs to be able to detect weak signals, amplify signals, and have appropriate anti-interference capabilities. Taking ECG measurement as an example, people use the differential voltage between two electrodes connected to the human body, or the differential voltage between multiple electrodes (for different lead requirements), and take the average value to reflect the state of the heart. Because electrical signals in the human body are very weak and difficult to detect, high-precision amplifiers are essential to measure these electrical signals. TI can address these applications by using different AFE products and setting up total system solutions. In the detection of ECG, we can use the ADS129x series (here, the ADS1292R is used as an example).

The ADS1292R fully integrates ECG detection and respiratory impedance measurement (RESP) for portable, low-power physiological signal measurement products. There are two low-noise PGAs and two high-resolution ADCs inside the device, which are used for the detection, measurement and amplification of weak electrical signals. At the same time, the gain of the PGA is optional, which can meet different application scenarios. The ADS1292R is very competitive in the AFE market due to its high level of device integration, which integrates functions such as the right leg drive circuit (RLD) and lead-off detection. For customer-specific applications, such as using multiple channels for both ECG and RESP detection and measurement, this can be easily implemented by paralleling two ADS1292Rs. More detailed parameters and usage methods can be found in the data sheet of ADS1292R.

TI provides AFEs with various channels and functional options for different customers, which can meet the application scenarios of different needs, and provide flexible solutions to achieve corresponding functions. In addition to diversified functions and channels, TI’s AFE also has certain advantages in terms of power consumption, noise performance, package size, etc. These characteristics need to be fully considered in the customer’s design. TI’s products can make the design more flexible and convenient, and can help Customers simplify PCB layout and reduce costs.

In addition to the ADS129x series, TI has many highly integrated products that can support various application scenarios. For example, the product AFE4500 can support the above functions as well as bioimpedance analysis and optical biosensing. By measuring bioimpedance, through algorithm calculation and derivation, the composition and physiological data of different substances in the human body can be obtained, such as body fat, moisture, etc. Some terminal products on the market have also realized how to quickly and conveniently obtain the physiological data of the human body. In addition, due to the integration of ECG, PPG and other functions, the use of AFE4500 in portable or smart wearable devices can simultaneously obtain different physiological data. The design not only simplifies the mutual interference of complex circuits and separation schemes, but also brings customers Highlights of the product. For consumers, an end product that can integrate multiple functional measurements must be a differentiated product. There are a wide variety of TI-based AFE products, and the following is a simplified selection table that can be used as a reference for your selection. For more AFE devices, you can check the reference link to learn more about TI’s AFE products.

Coexistence, Competition or Convergence: How Do 5G and Wi-Fi 6 Get Along?

【Introduction】Wi-Fi is a wireless local area network (LAN) technology that is mainly used indoors, such as at home or in the workplace. The cellular network used by operators is a wide area network (WAN) that can be used both indoors and outdoors. In the industry, the debate around the convergence of Wi-Fi and cellular networks has always been there. With the introduction of a new generation of wireless technologies, Wi-Fi 6 and 5G, a new round of debate has reignited – are the two converging, coexisting or competing?

The two different types of wireless technologies, Wi-Fi 6 and 5G, have coexisted for years, with Wi-Fi and cellular standards increasingly intertwined. Industry bodies including the Wi-Fi Alliance, IEEE, Wireless Broadband Alliance (WBA), Next Generation Mobile Networks Alliance (NGMN), and 3GPP are also joining the discussion, from standards development to potential applications, to enable 5G and Wi-Fi -The interaction and integration between Fi is the main attack direction.

Wi-Fi 6 and 5G

Two wireless technologies go hand in hand

The network standard of Wi-Fi is a variant of IEEE 802.11, and there are different versions such as IEEE 802.11a, 802.11b, and 801.11g. The working frequency band is 2.4 GHz or 5 GHz, of which the 2.4 GHz frequency band supports the IEEE 802.11b/g/n/ax standard, and the 5 GHz frequency band supports the IEEE 802.11a/n/ac/ax standard. Wi-Fi 6 is the Wi-Fi Alliance’s industry name for the IEEE 802.11ax standard in the IEEE 802.11 family of local area network equipment and Internet access standards. Limited security, scalability, and efficiency have always been challenges faced by traditional Wi-Fi technologies. Wi-Fi 6 based on the IEEE 802.11ax standard has significantly enhanced efficiency and performance, it can provide 4 times higher capacity and 75% lower latency, and the speed is almost 3 times that of the previous generation Wi-Fi 5.2.

As the number of Internet users continues to increase, Wi-Fi 6 is gaining enough market traction. According to the latest research report “Wi-Fi 6 Market Global Forecast to 2027” released by Markets and Markets, the global Wi-Fi 6 market size is expected to grow from USD 11.5 billion in 2022 to USD 26.2 billion in 2027, with a compound annual growth rate (CAGR) reached 17.9%, of which ease of deployment is one of the important reasons for Wi-Fi 6 to lead. If the enterprise just upgrades the existing Wi-Fi network to Wi-Fi 6, there will be no significant increase in cost, because Wi-Fi 6 is fully backward compatible, and the original previous generation Wi-Fi equipment It doesn’t have to be eliminated, it can still be used.

5G is the fifth-generation technology standard for cellular networks. Launched by 3GPP Release 15 in 2018 and commercialized by mobile network operators in 2019, 5G is considered a major upgrade to 4G and LTE. 5G networks offer 50 times the speed, 10 times the latency and 1,000 times the capacity of 4G/LTE. Its improved performance, such as increased speed, coverage, reliability and security, is expected to enable a host of new applications across a wide range of industries. Compared with Wi-Fi 6, the advantages of 5G are mainly reflected in service delay, mobile roaming and outdoor coverage. The disadvantage is that the cost of deploying 5G networks indoors is high, and there is a problem of poor terminal compatibility.

Wi-Fi 6 and 5G represent the latest emerging wireless standards in unlicensed and licensed spectrum, respectively, and both Wi-Fi and cellular technologies have come a long way over the years and have remained largely parallel. Neither technology alone can serve the full range of enterprise services and applications. It can also be said that cellular and Wi-Fi indirectly promote each other’s development. As users increasingly rely on high-speed Wi-Fi connections at home or in the office, this drives the need for the same connection quality over cellular networks. Likewise, the ubiquitous nature of cellular connectivity has sparked similar expectations for Wi-Fi, leading to increased emphasis on the development of features such as open roaming.

If we must make some comparisons between Wi-Fi 6 and 5G, from an application perspective, Wi-Fi 6 is superior to 5G in terms of spectrum, device ecosystem, network cost, ease of deployment, flexibility, and management requirements. . The shortcomings of Wi-Fi 6 are also obvious. It does not perform well in large-scale outdoor coverage scenarios and cannot meet ultra-low latency requirements (

5G and Wi-Fi6

Convergence or competition?

With 5G being heavily invested in media and advertising, one might expect that the next generation of wireless networks in the enterprise will revolve almost entirely around 5G, with Wi-Fi 6 being supportive at best. Is this really the case? Not so, as revealed in Deloitte’s 2021 Global Advanced Wireless Survey of 437 networking executives from nine countries. Of the respondents, 45% of enterprises are testing or deploying both Wi-Fi 6 and 5G in order to enable their advanced wireless network deployments. Nearly all respondents (98%) expect their organizations to use both technologies within three years. Over the next three years, 48 ​​percent of business spending on wireless networks will be on Wi-Fi and 52 percent on cellular technology.

Wi-Fi 6 and 5G share some similarities, such as their ability to achieve gigabit speeds and low latency. But the differences are also stark, mainly in terms of coverage, mobility support and cost.

Because of the lower cost of deployment, maintenance and expansion, especially if the access point needs to serve a larger number of users, Wi-Fi technology is well suited for smaller, less expensive local area networks and has become a popular choice in home and business environments. leading technology. Our commonly used PCs, tablets, smartphones, streaming media devices, televisions and printers are connected to the Internet almost exclusively by Wi-Fi technology.

While cellular networks such as 5G are mainly used for indoor and outdoor wide area networks, devices that move across large geographic areas, in addition to smartphones, 5G is now being deployed on a large scale in connected cars, smart cities, and even large-scale manufacturing operations. Given the extensive experience operating cellular networks, network providers can provide critical functions such as network security, privacy, etc. For some mission-critical services, such as those that require protection from device interference, 5G has clear advantages.

With the better integration of Wi-Fi 6 and 5G, network operators are also starting to direct and optimize traffic on both networks, for example, by shifting more traffic to Wi-Fi networks to reduce congestion on cellular networks. As 5G’s key partner in advanced wireless solutions, Wi-Fi 6 will play an important role in maximizing benefits for businesses through next-generation wireless connectivity. From the perspective of complementary advantages, most of the application scenarios we see are the mixed use of 5G and Wi-Fi6 technologies.

According to IDC, by 2025, more than 152,000 Internet of Things (IoT) devices will be connected per second globally. The advent of Wi-Fi 6 and 5G promises reliable connectivity for mission-critical IoT devices.

in retail business

Analyzing the data collected (purchasing history, inventory trends, and footholds, etc.), forecasting what products should be displayed where, how much of each product should be displayed, and how to develop the products, these decisions will become a breeze.

in manufacturing

Advanced wireless networks consisting of 5G and Wi-Fi 6 play a key role in connecting machines and equipment to drive smart factory solutions.

in healthcare

As 5G and Wi-Fi 6 work together, the healthcare sector can introduce telesurgery and remote diagnosis.

in supply chain and logistics

The rollout of 5G and Wi-Fi 6 has really changed the last mile interaction issue with end consumers.

in the Internet of Vehicles

A connected car can provide in-car Wi-Fi to the user’s device, while the car itself is connected to a 5G cellular network.

Typically, 5G is likely to take the lion’s share of public communications, but sales of Wi-Fi 6 devices are quietly surging. According to Deloitte, shipments of Wi-Fi 6 devices will surpass 5G devices by at least 2.5 billion in 2022, compared with about 1.5 billion 5G devices. Smartphones, tablets, and PCs are the most commonly used Wi-Fi 6-equipped devices, and Wi-Fi 6 is now being used on a large scale including wireless cameras, smart home devices, game consoles, wearables, and AR/VR headsets and other equipment.

The adoption of Wi-Fi 6 and 5G is seen as a strategic imperative that will usher in a new era of wireless access for businesses. With the convergence of Wi-Fi 6 and 5G, businesses can conduct business from anywhere while maintaining employee productivity and the best user experience. In 2021, the Wireless Broadband Alliance (WBA) and the Next Generation Mobile Networks Alliance (NGMN) jointly released a report highlighting the benefits of Wi-Fi6 convergence with 5G, noting that many use cases and verticals can be leveraged from both. Benefit from closer integration between technologies. In addition, 3GPP is increasingly looking to add standards to each new release to enable convergence between Wi-Fi and cellular networks. Likewise, the IEEE, which is sponsored by the Wi-Fi Alliance, has been discussing potential paths for the convergence of Wi-Fi 6 and 5G for years. Now, 83% of service providers, equipment manufacturers and enterprises worldwide will deploy or plan to deploy Wi-Fi 6/6E by the end of 2022, a key finding from the WBA’s latest cross-industry survey.

The latest development of Wi-Fi6

In April 2020, the Federal Communications Commission (FCC) voted unanimously to open the 6GHz band to unlicensed users. The Wi-Fi Alliance named the version of IEEE 802.11ax running at 6GHZ or above Wi-Fi 6E. Wi-Fi 6E can provide low latency and faster data rates, and provides up to seven 160MHz channels necessary for high-bandwidth applications, it greatly expands the available spectrum of Wi-Fi 6, solves the need for billions of words Data transmission problems in applications with knot speed, such as Internet of Things, unified communications, cloud computing, AR and VR, etc.

While Wi-Fi 6 and Wi-Fi 6E are the same technology, their spectrums are different. The frequency band of Wi-Fi 6E is located at 6GHz, which helps to expand the functionality and efficiency of Wi-Fi 6. In terms of compatibility, Wi-Fi 6E access points support backward compatibility, which means that existing Wi-Fi devices can still be used. In terms of shipments, in 2021, more than 50% of Wi-Fi product shipments will be Wi-Fi 6. IDC predicts that by 2025, shipments of Wi-Fi 6 products will reach 5.2 billion, of which 41% will be Wi-Fi 6E.

With the increasing popularity of smartphones around the world, the use of Wi-Fi technology is also increasing. Additionally, governments around the world are building smart cities with public Wi-Fi networks to help various service industries such as education and healthcare. These factors have increased Wi-Fi usage in homes, offices and public spaces, increasing sales of Wi-Fi chipsets.

According to data from the Wi-Fi Alliance, Wi-Fi users will demand more efficient, reliable and secure connections in 2022, with nearly 18 billion Wi-Fi devices expected to be in use. According to the Organization for Economic Co-operation and Development (Organization for Economic Co-operation and Development), by 2025, the number of households with computers worldwide is expected to increase to 1,262.47 million. The massive increase in computer usage has created a market opportunity for Wi-Fi chips.

Mordor intelligence forecasts indicate that the global Wi-Fi chipset market will grow at a CAGR of 4.4% between 2022 and 2027.More and more chip products supporting Wi-Fi 6 are on the market

The Qorvo QPF7552 is an integrated high-power front-end module (iFEM) designed for Wi-Fi 6 systems.

Dedicated 5G

Can it replace Wi-Fi 6/6E?

In the discussion of Wi-Fi 6 and 5G, there is such a word that appears very frequently, that is Private 5G (Private 5G). As the name suggests, private 5G must be related to 5G, and since the launch of 5G, 3GPP Release 16 has introduced 5G New Radio (NR) and enhancements to the 5G core for private networks. According to 3GPP TS 22.261, the following is the definition of a private 5G network:

• Private communications: communications between two or more UEs belonging to a restricted UE set.

● Private Network: An isolated network deployment that does not interact with the public network.

● Dedicated slices: Dedicated network slices are deployed for use by specific third parties only.

Private 5G is a secure and resilient next-generation wireless private network designed for custom enterprise use cases that demand ultra-high bandwidth, speed, reliability, and ultra-low latency on secure and private networks. Since private 5G networks consist of small cells, they provide better coverage. In most cases, dedicated 5G operates on unlicensed spectrum, such as CBRS spectrum in the US. However, operators offering dedicated 5G network-as-a-service can use other available spectrum in their dedicated 5G deployments to optimize their networks. In terms of applications, dedicated 5G will initially be used primarily for critical communications, such as factory automation or operational communications across large venues such as airports or distribution centers.

Compared with Wi-Fi 6/6E, dedicated 5G is similar in spectrum ownership mode, deployment mode and business operation support functions. To this end, there is a saying in the industry that dedicated 5G will replace Wi-Fi 6/6E. The reason is: Private 5G has the same advantages as public 5G networks, such as high throughput, huge capacity, low latency, and inherent security, so private 5G has advantages over Wi-Fi 6/6E in applications.

In practice, technologists have found that this is not the case. Not only will dedicated 5G not be a full-scale replacement for Wi-Fi6/6E, but Wi-Fi 6/6E will remain an excellent access option for low-cost network deployments. First, cheap Wi-Fi 6 network equipment, installation, and maintenance costs simply cannot be achieved with 5G or dedicated 5G. Secondly, in order to achieve wider network access, Wi-Fi 6/6E has been established and has larger capacity, and its transmission speed is comparable to wired.


The benefits of Wi-Fi 6 for enterprises are obvious. It can help enterprises quickly build their own networks, and build these networks according to service changes to meet the customized needs of enterprises. For example, an enterprise establishes an office network, and a school establishes a student network access network. In addition to traditional Wi-Fi scenarios, Wi-Fi 6 is also suitable for enterprise VR/AR/4K applications, warehousing and logistics AGVs, and asset management in supermarkets and factories.

5G focuses on public networks and is deployed in scenarios or endpoints with high roaming and latency requirements, such as autonomous vehicles, drones, outdoor personal network access, and factories with ultra-low latency requirements (less than 10ms).

Wi-Fi 6 and 5G are two different technologies that complement each other. Each technology addresses a specific business need or condition. Companies with large outdoor businesses may consider 5G for their wireless network needs. The wireless needs of small and medium businesses can opt for cost-effective Wi-Fi 6 solutions. Organizations with indoor operations or identified access points may opt to use Wi-Fi 6E for their 6 GHz-capable devices. The interoperability between Wi-Fi 6/6E and 5G networks provides seamless connectivity for users’ network applications, and jointly drives the success of network innovation.

As Wi-Fi 6/6E and 5G develop, their respective application areas are bound to overlap. Despite this overlap, the two technologies will remain complementary and neither can replace the other. It is this relationship of integration, coexistence and complementarity that indirectly promotes each other’s development.

Semiconductor industry is in deep recession, IHS says 5G is expected to reverse

The latest data from market research firm IHS Markit shows that the global semiconductor industry’s revenue in 2019 will fall by nearly 13% compared with last year, which means that the recession trend of the industry continues to worsen. But researchers at IHS Markit believe that 5G has the potential to reverse all that.

Len Jelinek, senior director of semiconductor manufacturing at IHS Markit, said that in the history of the semiconductor industry, every market downturn will end with the arrival of a certain innovative technology or product, and new technologies and innovative products can always stimulate a substantial increase in market demand. Such as the World Wide Web, iPhone, etc. Len Jelinek believes that 5G will take up this important task next. As the impact of 5G will extend far beyond the technology industry, it will change all aspects of human society, stimulate new economic activities, and drive the growing market demand for semiconductor chips.

IHS Markit expects that the global semiconductor market revenue will rebound in 2020, from $422.8 billion in 2019 to $448 billion, an increase of 5.9%. This may be a relief to the world’s top semiconductor companies such as Intel, Samsung, TSMC, Qualcomm, Broadcom, etc.

For the decline of global semiconductors in recent years, IHS Markit believes that it is mainly caused by the sharp drop in the prices of DRAM and NAND memory. Samsung also pointed out in an announcement that since the end of 2018, there has been a global oversupply of semiconductor components, which has led to declining industry profits. Samsung Electronics expects operating profit of around $6.5 billion in the third quarter of 2019, down 56 percent from $14.7 billion a year earlier.

However, the decline in 2019 should only be temporary, and the situation will be reversed in 2020. IHS Markit said that with the launch of 5G commercial services in major global markets, 5G smartphones will usher in a period of rapid growth, which will drive the semiconductor industry to resume growth. Smartphones are the largest consumer of the semiconductor industry, with global revenue expected to be $87.7 billion in 2019.

For the smartphone market, institutions such as IDC and Gartner agree with IHS Markit’s judgment that the market size will continue to decline in 2019 and return to growth in 2020. IDC expects the smartphone market to maintain a three-year downward trend in 2019, with a decline of about 2.2%, although 2020 will see a growth of 1.6%. Gartner believes that global smartphone sales in 2019 will be around 1.5 billion units, a year-on-year decrease of 2.5%. However, as 5G services enter the stage of large-scale commercial use in 2020, smartphone sales are expected to resume growth.

According to IHS Markit, the impact of 5G will be all-round, not only will it bring about an increase in smartphone sales, but also promote the development of new business models and support the digital transformation of all walks of life around the world, thereby bringing the semiconductor industry more opportunities. In the report, IHS Markit estimates that by 2035, 5G will generate $1.3-1.9 trillion in economic output in the U.S. alone — nearly as much as U.S. consumers spent on cars in 2016.

Of course, in addition to semiconductor and smartphone manufacturers, there will be more companies benefiting from the development of 5G, such as telecom operators. Operators such as Verizon and AT&T in the United States are actively deploying 5G networks, hoping to gain more opportunities for growth. Verizon expects spending on 5G to have a “significant” impact on its revenue as early as 2021.
