Technical Introduction

Zigbee wireless communication technology

Zigbee technology emerged in 2004, primarily utilizing free 2.4GHz high-frequency transmission to enable reliable wireless communication. Over more than a decade of continuous development and refinement, Zigbee has established itself as one of the most stable and efficient wireless protocols for short-range, low-power data transmission.

Here ZigBee wireless technical wide application ranges in smart lighting, home automation, industrial IoT, and building management systems, Zigbee supports scalable, secure, and energy-efficient networks.

Main advantages

1) No need for preliminary survey, can be installed on the lamp head in advance and installed together during construction.
2) Large number of networks, large capacity, relay transmission mode, not affected by power line attenuation, and the network mode can also resist interference caused by environmental obstructions.
3) The implementation of data transmission is also relatively high, and single point transmission is basically at the MS level;
4) Stable technology, using various IoT scenarios, in line with the current development path of IoT wireless technology;

Disadvantages

If the old project does not replace the lamp holder, it will either involve the cost of a second attempt to climb the vehicle, installed on the lamp holder, or installed for maintenance, but requires drilling holes to expose the antenna, which affects the appearance.
