E	Sensors and Smartphones

Explanation:

Detailed explanation-1: -ZigBee is all about a wireless protocol. It is an IEEE 802.15. 4-based specification for a suite of high-level communication protocols using in to create Personal Area Networks(PANs) with small, low-power digital radios.

Detailed explanation-2: -4 is a technical standard which defines the operation of a low-rate wireless personal area network (LR-WPAN). It specifies the physical layer and media access control for LR-WPANs, and is maintained by the IEEE 802.15 working group, which defined the standard in 2003.

Detailed explanation-3: -Zigbee is a wireless technology developed as an open global market connectivity standard to address the unique needs of low-cost, low-power wireless IoT data networks. The Zigbee connectivity standard operates on the IEEE 802.15.

Detailed explanation-4: -ZigBee is an IEEE 802.15. 4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios. Small range wireless networking protocol that primarily operates on the 2.4 GHz frequency spectrum.
