  • Patent number: 6785558
    Abstract: A method for transporting wireless communication signals between a base station hotel and remote cell sites with separately digitized RF carrier signals is provided. Separately digitized carriers are transmitted over a digital network between the hotel and the remote sites, remaining in digital format until reaching terminal antenna units. At the antenna units, downlink digital signals are converted to analog RF signals and transmitted, while uplink analog signals are received and converted to digital signals. A corresponding system comprising a base station hotel, at least one remote site, and a digital data network connecting the hotel to the remote site is provided. The hotel includes a plurality of base stations and a digital hub for interfacing the hotel to the network. The remote site includes a set of antenna units connected via a local data link to a network access node for interfacing to the network.
