Radiation Characteristics and Interference of Large Broadband Power Line (BPL) Deployments

We analyze and quantify the radio interference to aeronautical receivers from a massively deployed broadband over power line (BPL) system. Based on our previous semi-finite multi-line model, a closed-form solution is derived for the far field using the saddle-point method. We investigate the aggregate radiation power from a circular area in which randomly oriented BPL spans are uniformly placed. A scaling rule for the radiation power is discovered, with respect to both the number of BPL spans and the altitude of the receivers. The level of interference is numerically evaluated for a baseline case. The result can be generalized using the scaling rule derived here.
