Just like Wi-Fi, ZigBee is a standardized wireless technology for home as well as for industrial applications. In many ways, ZigBee is a low-power, low-data-rate version of Wi-Fi. Like Wi-Fi, it can transmit a signal through walls, floors, furniture, etc. ZigBee uses the same basic security and anti-interference technologies as Wi-Fi, and uses the same radio spectrum as Wi-Fi and Bluetooth (2.4 GHz). But compared with Bluetooth, it offers much greater range and the ability to network various devices together, which Bluetooth does not offer.
