Abstract
A method of upstream communication over a linear broadband network includes the steps of generating an upstream baseband signal and modulating it onto an upstream wireless radio frequency carrier to produce a first upstream modulated carrier signal. The modulated carrier signal is transmitted wirelessly, received, and demodulated to reproduce the information integrity of the upstream baseband signal. The signal is then modulated onto an upstream linear broadband radio frequency carrier for transmission on the linear broadband network. Advantageously, noise that accumulates at the subscriber premises is removed from the upstream signal prior to presentation of the signal to the upstream path of the linear broadband network. A system for communicating over a linear broadband network includes network access interface devices coupled to the linear broadband network. A subscriber access interface device accepts upstream communication signals and modulates and transmits the signal to the network access interface device. The network access interface device 6 receives and demodulates the signal and then modulates it for transmission on the linear broadband network.
