Technical Introduction
Zigbee wireless communication technology
It emerged in 2004, mainly through free 2.4G high-frequency transmission. After more than a decade of development, it is one of the stable wireless communication methods, suitable for multi node data transmission in the region.
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.
