In recent years, the development of communication technology has been very rapid, especially in consumer scenarios, there have been many applications, today we will discuss the application and prospect of low-power wireless technology.
In terms of communication distance and networking methods, it is divided into local area networks and wide area networks. In terms of application scenarios, it is divided into high-rate multimedia audio and video, medium-rate wireless audio streaming media, and low-rate control sensor data. In order to adapt to different application scenarios, these standard forms jointly construct a rich and moving modern information world.
With the rapid increase in the number of smart devices, more and more devices need to have networking capabilities. It is predicted that by 2020, there will be twice as many devices with wireless communication capabilities as in 2019. Among them, the largest proportion is low-power wireless LAN equipment.
Taking smart accessories as an example, more and more devices support the DDA protocol. The DDA communication protocol is mainly the same as the data transmission of the Internet of Things, which can control home electrical equipment and can also be used for safety sensors. In smart homes and even smart cities, smart transportation has great application prospects.
In terms of networking, DDA often uses star networking, where the gateway is the center, and other devices are connected to the gateway through the DDA protocol. The advantages of this networking method are simple and easy to use, and the networking method is clear and intuitive. Users can pair and use devices through very simple connection logic. Damage to other terminals will not affect the operation of the entire network.
The world of the future must be fully interconnected, and humans can access it through all kinds of devices. Sensor nodes need low power consumption, two-way transmission, security, IP addressability, and have certain node computing capabilities to realize edge computing. Clouds need to realize data modeling and analysis based on artificial intelligence, and finally make decisions and executions. .
As far as low-power wireless networks are concerned, the complexity of application scenarios determines that no network can be applied to all scenarios. For a long period of time in the future, multiple communication protocols will coexist. After market testing, Take a certain communication technology as the mainstream communication technology.
