4、Why PLC
Under the premise of using power line supply,PLC-IOT technology has the following advantages over other communication technology :
a、Longer distance and higher aata rate
No need to worry about the signal attenuation caused by building blocks, the theoretical transmission distance can reach 5KM.
Compared with 2.4G communication technology, the channel environment is more simple. Provides 200Kbps data rate of application layer, and ensure the immediacy of IOT products communication.
b、Convenient construction,operation and maintenance, electricity can be realized anytime
No need to pay attention to topology,as long as the guarantee of equipment power supply,communication can be realized.
No need to consider the deployment of relay nodes,as long as under the same power transformer supply environment, communication can be realized as well.
c、Ability to isolate communication areas with simple and economical solutions
Could be isolated communication areas by simple shunt capacitors to avoid interference between communication areas.
Realize the non perception AD-HOC network in the same communication areas.
 
Product Overview
