Although most of the current wearable devices are still focused on smart watches, smart bracelets, immersive glasses, etc., their exploration space has changed a lot. From the elderly to babies, from headsets to socks, from outside the body to inside the body, the exploration of wearable devices extends to almost every part related to the human body.
In the near future, physical screens will disappear and be replaced by virtual screens displayed in any space, either in space, on the wrist, or of course through vision through glasses. When this technology enters commercial application, it will be inevitable to replace the current smartphones, but there is still a key element in this, which is data transmission technology.
We can use the sensor technology of wearable devices to digitize any part of the body, including dynamic and static life posture characteristics, behavioral habits, lifestyle, etc. If these data are transmitted to the big data processing center in the cloud in real time and effectively, and at the same time, it is also necessary to ensure that the data analysis and processing results can be fed back to the users in real time and provide scientific guidance to the users, this means that the data transmission can be Wearable devices are a very critical value point.
Although a large number of companies are currently entering the wearable device industry, both large and small companies are working hard to develop various wearable devices in the hope of seizing this business wave. The technology giants we all know hope to be in this wave. Lead the industry. For example, Google Glass has been attracting 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 smart keys that connect people and things, wearable devices have obviously extended from digital monitoring of people to monitoring and connecting things. In the field of smart homes, some manufacturers have tried to connect and control systems such as smart door locks, home lighting, and smart appliances based on wearable devices; in the field of smart cars, some manufacturers have also tried to replace car keys with wearable watches and achieve More intelligent control of cars; in the field of financial payment, some manufacturers have integrated NFC technology based on wearable devices to realize payment in subways, buses, etc. Although the relatively small physical screen of wearable devices currently brings an imperfect experience to users, with the application of voice interaction technology and the development of virtual reality technology, this problem will soon be solved.
When display and connection are no longer a problem, the problem of real-time interconnection is right in front of us. How to realize the interconnection between devices, how to realize the interconnection between people and devices, how to realize the interconnection between data, and how to realize the interconnection between devices and the entire Internet of Things? These issues have obviously reached 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 usually used; in smart homes, wireless technologies such as Wi-Fi, Bluetooth, ZigBee, and infrared transmission are usually used. and other technologies. But in the era of wearable devices where everything is connected, the question is not whether there is an Internet connection between things, or between people and things, 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. Of course, mobile cellular technology is also participating in the competition. But judging from the current situation, it is difficult to give up any one of these technologies, because they all have their own strengths and weaknesses.
For example, the field of communication-based smart watches or smart glasses based on wireless network transmission requires the help of current mobile 4G technology. In the medical field, Bluetooth is more popular, especially with Bluetooth 4.0 low-power technology, which can last for up to a year or even longer with the help of a button battery. This is something that Wi-Fi technology is currently unable to satisfy. Current Wi-Fi technology generally consumes relatively large amounts of power. On the one hand, it consumes more power, and on the other hand, it is easy to cause interference to some medical equipment. Therefore, it is used in the field of mobile medical care. Relatively small.
This allows us to see that with the intelligence 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 diverse and each has its own strengths, this is only the current stage of development.
In my opinion, the future wireless transmission technology will generally have two development directions: First, it will make breakthroughs based on one of the wireless transmission technologies, integrate the advantages of multiple wireless communication technologies, improve the shortcomings, and become a mainstream wireless transmission technology. Transmission technology; second, there will be multiple wireless transmission technologies on future wearable devices or smart devices, and the devices will automatically identify and select the optimal wireless transmission solution based on the environment.
