ABSTRACT
This chapter discusses the broadband over power line (BPL) radio frequency interference problem, examining why power lines act as antennas and how certain frequencies used for communications are adversely affected by the transmission of data over power lines. Radio frequency (RF) radiation represents a two-way street. External radiation can induce current into a conductor, which can adversely affect transmission. The chapter examines the effect of power line properties on the transmission of data, including interference resulting from transmitting data over power lines. The neighborhood or distribution transformer closest to the BPL subscriber represents a major barrier to providing data services. One of the more vocal groups against the spread of BPL is the American Radio Relay League, a worldwide organization of amateur radio operators headquartered in Newington, Connecticut. Several methods can be used to either prevent or reduce BPL interference to other RF services.
