Distributed antenna system for wireless network systems
First Claim
1. A master unit for a telecommunications system, the master unit comprising:
- an analog interface configured for receiving RF signals from at least one base station and digitizing the RF signals to generate first digitized RF signals;
a digital interface configured for receiving second digital signals transmitted in digital form from the at least one base station, wherein the digital interface comprises;
a resampler configured for re-sampling the second digital signals into re-sampled second digital signals having a data rate that is less than an original data rate of the second digital signals;
a combiner configured for combining the first digitized RF signals and the re-sampled second digital signals into a combined digital signal; and
a transmitter configured for providing the combined digital signal to a remote unit capable of wirelessly transmitting information represented by at least part of the combined digital signal, wherein the data rate corresponds to a bit rate of a network coupling the master unit to the remote unit.

Abstract
A distributed antenna system is provided for communicating with a plurality of base stations. The distributed antenna system includes a system controller and a master unit communicating with at least one of the plurality of base stations. A remote unit communicates over a high data rate media with the master unit and/or a downstream remote unit. Alternatively, the distributed antenna system includes a controller and a digital time/space crosspoint switch controlled by the controller. A digitizing transceiver is in communication with the digital time/space crosspoint switch. The crosspoint switch is configured to transmit and receive digital data through the digitizing transceiver.

19. A method, comprising:
-
receiving, by a first unit, analog RF signals from a first base station; digitizing, by the first unit, the analog RF signals to generate first digitized RF signals; receiving, by the first unit, second digital signals transmitted in digital form from a second base station; re-sampling, by the first unit, the second digital signals into re-sampled second digital signals having a data rate that is less than an original data rate of the second digital signals; combining, by the first unit, the first digitized RF signals and the re-sampled second digital signals into a combined digital signal; and providing the combined digital signal to a second unit located remotely to the first unit over a communication medium, wherein the data rate corresponds to a bit rate of the communication medium.
