Abstract With the rapid development of broadband carrier communication technology, the power line communication market is growing. However, the frequency band of power line communication overlaps with other radio services, mainly the High Frequency (HF) radio services. In addition, power line communication may have electromagnetic leakage in the open air. Large-scale power line communication system will give a much greater interference to some critical HF radio services. In this paper, the standards and researches relative to the power line communication system are reviewed. Based on existing studies, impact analysis which includes the impact probability and severity of the power line communication system on HF equipment is proposed. In addition, explicit explanations are provided. The proposed impact analysis methods are applied to simulations and evaluations. Numerical results demonstrate that a large-scale power line communication system will cause additional ambient noise, which affects the performance and reliability of HF equipment with a high probability.
