1. A telecommunications system, comprising:

  • a head end unit configured for communicating channelized digital baseband signals with remotely located units, wherein the channelized digital baseband signals include call information for wireless communication, the head end unit including;

    channelizer circuitry configured for extracting, per channel, the channelized digital baseband signals, the channelizer circuitry including, per channel;

    a channel filter;

    an interpolator; and

    a mixer associated with an oscillator; and

    transport circuitry configured for formatting the channelized digital baseband signals for transport together to the remotely located units; and

    a remotely located unit positionable remote from the head end unit, the remotely located unit being configured for wirelessly communicating with mobile devices, the remotely located unit comprising;

    remote channelizer circuitry configured for providing, per channel, uplink channelized digital baseband signals, the remote channelizer circuitry including, per channel;

    a remote channel filter;

    a remote interpolator; and

    a remote mixer associated with a remote oscillator; and

    remote transport circuitry configured for formatting the uplink channelized digital baseband signals for transport together to the head end unit.
