1. A method of communicating via a wireless access architecture comprising a plurality of cell sites coupled to main switching point means and a digital broadband backhaul connected between the plurality of cell sites and the main switching point means, the method comprising the steps of:

  • executing first operations at the cell sites on communication signals communicated with cellular users, the first operations comprising the steps oftransmitting communication signals to and receiving communication signals from the cellular users,amplifying the communication signals,converting the communication signals between digital and analog signals, andcommunicating with the main switching point means through the digital broadband backhaul using the communication signals; and

    executing second operations on the communication signals from the cell sites at the main switching point means, the second operations comprising the steps ofmodulating or demodulating the communication signals, andbit steam processing the communication signals.
