Here are the 12 kinds of wireless technologies. Who will become the main theme of the Internet of Things?
The Internet of Things, all things are connected. In this era, more and more objects will be connected to the Internet, and finally, realize the connection to the host/cloud. These connections, we can use a variety of communication links to achieve.
However, the device itself is generally connected to the Internet of Things system wirelessly. This wireless connection is the most important or weakest link in the system. Therefore, it is important to choose a wireless technology that can match the device and its surrounding environment. This article describes several wireless candidate technologies that are most likely to be adopted for new designs.
The device is connected to the gateway wirelessly is a typical IoT connection scenario. A gateway is an interface that connects to the Internet through a public broadband cable or DSL modem and then connects to the Internet through an Internet service provider.
In another application scenario called machine-to-machine (M2M), the device connection will go through a cellular operator, and then to another operator, or directly to the Internet.
