Re: UPLOAD speed sucks really bad... BPL *could* work fine on UHF and above frequencies, as those signals do not propagate around the world like HF and sometimes low band VHF. Even very low power signals in the HF portion of the spectrum will propagate easily, and can travel around the world. This will cause a problem when those signals are interference, and are traveling on wires that happen to be excellent radiators (antennas) for the frequencies in operation. If the frequency was increased, the power lines would be less efficient radiators, and will inherently cause less interference. Secondly, because of the nature of UHF/SHF/Microwave propagation, what interference that did escape would not travel nearly as far as it would if it were @ HF.
This technology isn't purely evil, but it in it's current state it is far from being ready for deployment. Experiments with BPL in the upper frequency bands have proven viable.
