A communications network for providing two-way data transfer, including a distribution hub, a plurality of subscriber locations for receiving downstream data signals from and transmitting upstream data signals to the distribution hub, a wired network connecting the distribution hubs to the plurality of subscriber networks, at least a portion of the wired network including a coaxial cable television plant, at least a portion of the coaxial cable television plant between the distribution hub and an intermediate location being enabled for transmitting downstream data signals, and a terminal portion of the cable television plant extending from the intermediate location to the plurality of subscriber locations being enabled for transmitting upstream and downstream data signals. A wireless transmitter at the intermediate location is provided for receiving, over the terminal portion, upstream signals from the plurality of subscriber locations, and transmitting the upstream signals modulated as wireless communications signals. A wireless receiver is provided for receiving and demodulating the wireless communications signals to produce the upstream signals at the distribution hub.
