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. |

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.
