摘要
In one example, a system comprises a central unit and a radiating point located remotely from the central unit and communicatively coupled to the central unit. The radiating point is configured to provide radio frequency signals to a coverage zone via one or more antennas. The system further comprises a radar sensor communicatively coupled to the radiating point and configured to capture image data in the coverage zone of the radiating point, wherein the radar sensor includes a plurality of transmitters and receivers coupled to an antenna array. One or more components of the system are configured to determine user detection data for users in the coverage zone based on the image data captured by the radar sensor and adjust the power consumption of the radiating point based on the user detection data.

The radar sensor 122 can be integrated with the remote antenna unit 104, which could include, for example, mounting the radar sensor 122 inside the housing of the remote antenna unit 104. In other examples, the radar sensor 122 is mounted near the remote antenna unit 104 but not within the same housing. It should be understood that the DAS 100 can include a subset of remote antenna units 104 with an integrated radar sensor 122 and another subset of remote antenna units 104 where the radar sensor 122 is mounted near the respective remote antenna unit 104. The radar sensors 122 can be powered internally or externally by the remote antenna units 104 or another source of power.
