In a typical IoT project, a lot of protocols are involved to make sure that the requirements are met. They are divided into different layers. The following are some well-known IoT protocols:
- Wi-Fi: This is a widely used protocol among IoT developers. It is based on IEEE 802.11 standards. It uses 2.4 GHz and 5 GHz as band frequencies, with about 50 meters as a range. Usually, it can transfer 150-200 Mbps of data.
- Z-Wave: This is an RF communications technology with a low power capacity. It is widely used in sensors and home automation products with a 100 Kbps data rate. It can control a maximum of 232 devices, with a range of 30 meters.
- Zigbee: This is like Bluetooth. It is based on the IEEE 802.15.4 protocol, and it operates ...
