Abstract:
A distributed antenna system (DAS) includes: signal interface units to receive downlink asynchronous radio carrier signals for radio frequency carriers from external device(s), each having a different clock, the signal interface units configured to: re-clock the downlink asynchronous radio carrier signals to a master clock of the DAS and convert the downlink asynchronous radio carrier signals to downlink digital signals; a host unit communicatively coupled to signal interface units and configured to combine at least two downlink digital signals into an aggregate downlink digital signal; an antenna unit coupled to the host unit and configured to: receive the aggregate downlink digital signal from the host unit, convert the aggregate downlink digital signal(s) and/or another signal based on the aggregate downlink digital signal into downlink radio frequency signals, and wirelessly transmit downlink radio frequency signals to a subscriber unit.
