Abstract
One embodiment is directed to a digital antenna system (DAS). The DAS comprises a host unit and at least one remote antenna unit located remotely from the host unit, wherein the remote antenna unit is communicatively coupled to the host unit. The host unit is configured to communicate a downstream transport signal from the host unit to the remote antenna unit. The remote antenna unit is configured to use the downstream transport signal to generate a downstream radio frequency signal for radiation from an antenna associated with the remote antenna unit. The DAS is configured to enable full operation of the remote antenna unit in the DAS if an authentication process has been successfully performed for the remote antenna unit, wherein full operation of the remote antenna unit in the DAS is not enabled if the authentication process has not been successfully performed for the remote antenna unit. Other embodiments are directed to a host-to-host network.
