Why doesn the FCC allocate dedicated spectrum for BPL?
There are two main reasons for this. The first is quite simply there is not enough open space in the HF spectrum to accommodate a dedicated allocation for BPL. Current BPL systems need at least ten MHz of spectrum. Newer, faster systems may need 25 MHz or more to operate. Accommodating such systems would require the entire HF spectrum to be allocated to BPL. The second reason against a dedicated frequency allocation is that BPL doesn’t actually use the wireless spectrum, it emits energy in the frequency range, thus polluting it. An analogy would be building a highway and dedicating it to one industry or group of people so they could dump garbage on it.
