* Comparing the IEEE 802.15.4 ZigBee standard  with Bluetooth and IEEE 802.11 WLAN helps us understand how ZigBee differentiates itself from others (see Figure below).  ZigBee has the lowest data rate and complexity among these three standards and provides significantly longer battery life. For Smart Home Automation, where the goal of wireless communication is to transmit and receive simple commands and/or gather information from sensors such as temperature or humidity sensors, ZigBee provides the lowest power consumption and the most cost-efficient solution compared to Bluetooth and IEEE 802.11b
