Digital distributed antenna systems and methods for advanced cellular communication protocols
First Claim
1. A digital distributed antenna system, the system comprising:
- a host unit;
a plurality of remote antenna units each communicatively coupled to the host unit, wherein a downlink digitized RF signal is transported from the host unit to at least one of the plurality of remote antenna units, and wherein the at least one of the remote antenna units is configured to generate an analog RF signal from the downlink digitized RF signal; and
a signal conditioning and control module that extracts from a first digitized RF signal at least one data stream and converts the at least one data stream to baseband data.

15. A method for a digital distributed antenna system, the digital distributed antenna system including a host unit, and a plurality of remote antenna units each communicatively coupled to the host unit, wherein a downlink digitized RF signal is transported from the host unit to at least one of the plurality of remote antenna units, and wherein the at least one of the remote antenna units is configured to generate an analog RF signal from the downlink digitized RF signal, the method comprising:
-
receiving a digitized RF signal at a signal conditioning and control module associated with a first remote antenna unit of the plurality of remote antenna units; with the signal conditioning and control module; extracting from the digitized RF signal at least one data stream; down-converting the at least one data stream to baseband data; and generating an up-converted stream of digital RF data from the baseband data. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
