Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a standing wave detection device and method of a multi-frequency combiner. Background technique

[0002] Multi-system access platform (POI, Point Of Interface), as an effective mobile communication signal access device, is widely used in signal coverage of subways, tunnels, and large venues. With the deepening of the concept of co-construction and sharing, POI has also become one of the means for base stations to combine signals. POI is a key device in the mobile communication link. Once a failure occurs, the entire communication link will be interrupted, causing a great impact. Therefore, how to monitor the operating status of POI equipment has become the focus of attention of users.

[0003] POI is essentially a passive combiner device. The most common and effective way to monitor the status of this type of device is to monitor its ports, especially the standing wave ra...
