Interface device providing power management and load termination in distributed antenna system
First Claim
1. An interface device for a distributed antenna system, the interface device comprising:
- a port configured to communicatively couple the interface device to a base station;
a switching component coupled to the port, wherein the switching component is switchable from a first configuration to a second configuration, the first configuration connecting the port to a downlink path from the interface device to the distributed antenna system, the second configuration connecting the port to a load;
a first power detector communicatively coupled to the port and configured to measure a signal power of an input signal provided via the port;
at least a second power detector communicatively coupled to the downlink path and configured to measure a signal power of a gain-adjusted signal traversing the downlink path; and
at least one switchable hybrid module in the downlink path.

Abstract
Certain aspects involve an interface device for a distributed antenna system (“DAS”). In some aspects, the interface device can include an interface, a power detector, and a processor. The interface can include one or more ports for communicatively coupling the interface device to a base station and a switch that is switchable between first and second configurations. The first configuration connects a port to a downlink path of the DAS, and the second configuration connects the port to a signal reflection path. The processor can switch the switch between the first and second configurations based on a signal power measured by the power detector at the port. In other aspects, the interface device can include additional ports and termination loads. The processor can cause a signal path to be connected to a termination load instead of a port based on the port being disconnected from a unit of the DAS.
