zigbee wireless data transmission

zigbee? Applications of Zigbee Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this agreement is a short-range, low-power wireless communication technology. The name comes from the eight-character dance of bees, because bees rely on the “dance” of flying and zig-zagging wings to communicate the location of pollen to their companions. That is to say, bees rely on this method. constitutes the communication network in the group. It is characterized by short distance, low complexity, self-organization, low power consumption, low data rate, and low cost. It is mainly suitable for use in the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless networking communication technology.
