How to control EMC in a multi-module network of power line carrier PLC?

Controlling the EMC of a multi-module PLC network requires unified planning of frequency points and protocols. Each module is assigned a unique ID and time slot, and the TDMA protocol is used to avoid conflicts. Frequency hopping technology is used for frequency allocation to reduce co-channel interference. Differential signals are used for inter-module communication, with impedance matching of 100Ω. A common-mode inductor CML4532A-510T is installed on the network backbone to suppress common-mode noise. The EMC status of each module is monitored through a network management system, and parameters are dynamically adjusted. In actual testing, in a 100-module network environment, the system bit error rate should be below 10^-5. Controlling the networked EMC can support large-scale deployments, such as smart communities.
