4.5. Channel Capacity
Channel capacities for in-house power lines can be calculated against background and ingress noises. The received signal power is dependent on the transmit signal power and the insertion loss of a power line connection. The transmit signal power is limited by the radiation from the nearby electromagnetic field strength. By imposing a field strength of about 30 dBµV/m, the allowed PSD can be estimated to be between –72 dBm/Hz and –52 dBm/Hz according to
Equation 4.36
where we have used CFs in the range of between –65 and –45 dB at a distance of about 30 m. Figure 4.29 shows a simulated power line channel model, a simulated ...
