ZigBee uses unlicensed frequency bands but operate at slower speed or data rates.
ZigBee: This communication is particular designed for control and sensor networks on IEEE 802.15.4 requirement for wireless personal area networks (WPANs), and it is a outcome from Zigbee alliance.
This communication level defines physical and (MAC) which is refereed to as the Media Access Control layers to manage many devices at low-data rates.
