1. A distributed antenna system, comprising:

  • a head end unit configured to communicate channelized digital baseband signals with remotely located units, the channelized digital baseband signals including call information for wireless communication, the head end unit including circuitry configured to;

    receive downlink signals from at least one base station;

    process the downlink signals into downlink channelized digital baseband signals using a channelizer circuitry including a channel filter, an interpolator, and a mixer associated with an oscillator;

    format the downlink channelized digital baseband signals for transport together;

    packetize and packet schedule the downlink channelized digital baseband signals into downlink packetized baseband signals; and

    transmit the downlink packetized baseband signals to the remotely located units.
