Introduction ZigBee® and Bluetooth® are wireless communication protocols that provide a set of specifications for devices to transmit information wirelessly. The newer Bluetooth protocol, Bluetooth Low Energy (BLE) or Bluetooth Smart, was introduced as a low-power protocol, while the original Bluetooth is now referred to as Bluetooth Classic. Launched in the 1990s, the older technologies … Read more
In addition to 3G/4G/5G, Bluetooth, WIFI, and RFID, the Zigbee protocol also supports the Internet of Things (IoT)! Now, let’s take a closer look at how many layers the Zigbee technology protocol consists of. 1. The Zigbee protocol stack is a key element in supporting IoT applications.
