Wearable devices or promote the convergence of wireless technology

       Although most of the current wearable devices are only concentrated on smart watches, smart bracelets, immersive glasses and the like, but the exploration space has changed a lot. From the elderly to babies, from head-mounted to socks, from outside to inside, the exploration of wearable devices extends to almost every part related to the human body.

        In the near future, the physical screen will disappear, replaced by a virtual screen displayed in any space, either in space or on the wrist, of course, it may be imaged through the vision of glasses. When this technology enters commercial application, it is inevitable to replace the current smart phone, but there is also a key element in it, that is, data transmission technology.

       Through the sensor technology of wearable devices, we can digitize any part of the body, including dynamic and static vital features, as well as behavior habits and lifestyles. If these data are transmitted to the big data processing center in the cloud in real time and effectively, the results of data analysis and processing can also be fed back to the user in real time and provide scientific guidance to the user, which means that data transmission is possible A very key value point of wearable devices.

       Although a large number of enterprises are currently entering the wearable device industry, large and small enterprises are working hard to develop various wearable devices in the hope of catching this business wave, and the well-known technology giants hope to be in this wave Lead the industry. Google Glass, for example, has been receiving attention since the day it was born, and has also raised different questions. Intel not only launched smart bracelets, but also developed wearable devices including voice assistant headsets and baby monitoring jumpsuits.

        As a smart key connecting people and things, the wearable device has obviously extended from the single data monitoring of people to the monitoring and connection of things. In the field of smart homes, some manufacturers have tried to connect smart door locks, home lighting, smart home appliances and other systems based on wearable devices, and achieved control; in the field of smart cars, manufacturers have also tried to replace car keys with wearable watches and realized More intelligent control of cars; in the field of financial payments, manufacturers have implemented NFC technology based on wearable devices to realize subway and bus payments. Although the relatively narrow operation of the physical screen of the wearable device presents users with an imperfect experience, with the application of voice interaction technology and the development of virtual reality technology, this problem will soon be resolved.

         When the display and connection are not a problem, the problem of real-time interworking and interconnection is in front of us. How to realize the interconnection and interconnection between devices, how to realize the interconnection and interconnection between people and devices, how to realize the interconnection and interconnection between data, and how to realize the interconnection and interconnection between devices and the entire Internet of Things? These issues have obviously arrived at the time to be considered.

          Although today's smart devices are increasingly relying on wireless technology, or mobile Internet access to the network, there are many types of wireless communication technologies. For example, in smart watches, smart bracelets, and smart glasses, Wi-Fi, Bluetooth, or mobile cellular technologies are commonly used; wireless technologies in smart homes generally use Wi-Fi, Bluetooth, ZigBee, and infrared transmission. And other technologies. But in the era of wearable devices where everything is connected, the problem is not whether there is an Internet connection between objects, or between people, but whether there is an effective connection between them.

         In recent years, with the rise of the wearable device industry, wireless transmission technology has attracted attention and has developed faster. With the rise of two wireless transmission technologies, Wi-Fi and NFC, Bluetooth technology in the mobile phone era has been continuously compared and discussed between the two, and of course, mobile cellular technology is also participating in the competition. But as far as the current situation is concerned, it is difficult to give up one of these technologies, because each has its own advantages and disadvantages.

         For example, the field of smart watches based on communication, or smart glasses based on wireless network transmission, need to rely on the current mobile 4G technology. In the medical field, Bluetooth is more popular, especially in Bluetooth 4.0 low-power technology, only need to use a button battery, you can maintain a period of up to one year of work, or even longer. This is currently difficult to meet with Wi-Fi technology. The current Wi-Fi technology generally consumes a lot of power and power. On the one hand, it consumes more power, and on the other hand, it is easy to cause interference to some medical equipment. Relatively small.

         This allows us to see that with the intelligentization of wearable devices and the development of the Internet of Things, wireless transmission technology has become a core connection technology. Although the current wireless transmission technologies are diversified and have their own strengths, this is only a current stage of development.

         In my opinion, the future wireless transmission technology will generally have two development directions: first, it will make a breakthrough based on one of the wireless transmission technologies, integrate the advantages of multiple wireless communication technologies, improve the disadvantages, and become the mainstream wireless Transmission technology; Second, there will be multiple wireless transmission technologies on the wearable device or smart device in the future. The device will automatically recognize and select the optimal wireless transmission scheme to work according to the environment.
