Overview of Short-range Wireless Communication Protocol

With the continuous development of electronic technology and communication technology, the Internet of Things technology is changing with each passing day. The Internet of Everything has entered into each of our lives. Therefore, the communication between smart devices and smart devices has become very important, so that short-range wireless Communication technology has received widespread attention. Bluetooth (IEEE 802.15.1), ZigBee (IEEE802.15.4), Wi-Fi (IEEE 802.11), and NFC are currently several popular short-range wireless communication protocol standards. The article first introduces each in turn, the key technical points of the communication protocol, and then the main features of each protocol are compared, including network topology, coverage, data transmission rate, security, and power consumption.
