Which statement about ZigBee technology is true?
A . It has low power consumption.
B . It is designed only for point-to-point communications.
C . It ranges up to 250 meters.
D . It supports data rates up to 1 and 2 Mb/s.
Answer: A
Explanation:
ZigBee is based on the IEEE 802.15.4 protocol for WPAN, and aims at developing hardware and applications with a low data rate but also low power consumption and low complexity –for example, to control sensors. ZigBee-based products can access up to 16 separate 5 MHz channels in the 2.4 GHz band and are not compatible with 802.11 devices. The maximum power of ZigBee is 60 mW. Devices use low.
