Uplink path integrity detection in distributed antenna systems
First Claim
Patent Images
1. A distributed antenna system, the system comprising:
- at least one master unit;
a plurality of remote antenna units each in communication with the at least one master unit; and
a system controller configured to;
determine a noise figure for an uplink path from at least one of the plurality of remote antenna units; and
modify a gain of the uplink path when the noise figure exceeds a desired threshold, wherein the noise figure is determined as a function of a measured signal power of an undesirable signal component in the uplink path from the remote antenna unit.

Abstract
Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes at least one master unit; a plurality of remote antenna units each in communication with the at least one master unit; and a system controller configured to: determine a noise figure for an uplink path from at least one of the plurality of remote antenna units; and modify a gain of the uplink path when the noise figure exceeds a desired threshold, wherein the noise figure is determined as a function of a measured signal power of an undesirable signal component in the uplink path from the remote antenna unit.

11. A method for uplink path integrity in a distributed antenna system, wherein the distributed antenna system comprises at least one master unit and a plurality of remote antenna units each in communication with the at least one master unit, the method comprising:
-
determining with a system controller, a noise figure for an uplink path from a first remote antenna unit of the plurality of remote antenna units; and modifying a gain of the uplink path when the noise figure exceeds a desired threshold, wherein the noise figure is determined as a function of a measured signal power of an undesirable signal component in the uplink path from the first remote antenna unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
