1. A method for providing redundancy in a wireless hub, comprising:

  • receiving a plurality of upstream signals;

    amplifying each upstream signal with a separate low noise amplifier;

    down converting the output of each of the low noise amplifier by utilizing a separate down converter;

    receiving a down converted signal from each down converter with a separate receiver;

    providing a data signal from a receiver;

    when no data signal is provided by one of the receivers, selecting an alternate low noise amplifier to amplifier the associated upstream signal; and

    when no data signal is provided by one of the receivers after selecting an alternate low noise amplifier, providing the output of the low alternate noise amplifier associated with the receiver to a redundant down converter, the redundant down converter providing a redundant down converted signal to a redundant receiver.
