A customer premises installation has a wireless multimedia center (WMC) for reception from one or more signal sources and for distribution of segments of signals from signal sources through the wireless multimedia center to a plurality of end units, in which the signals include video signals and broadband data. The wireless multimedia center receives all the signals and distributes segments of said signals via a transmitter. The video signals are transmitted by orthogonal frequency division multiplexing in which all signals are added together and summed as an orthogonal array having dimensions of time, frequency and amplitude, to transmit spread spectrum multiplexed signals. Each pulse has sufficiently long individual pulse widths to defeat multi-path, reflection and absorption phase induced losses. The video signals are distributed to one or more end units. The end units communicate with the wireless multimedia center, controlling which segments of which signals are distributed to each end unit.
