Abstract
The embodiments described herein are directed at techniques to perform antenna/cable disconnection using co-located communication devices. A first device may transmit a reference signal over a predetermined bandwidth. A parasitic signal corresponding to the reference signal may be received via coupling at a second device that is co-located with the first device. The second device may be coupled to a first end of a cable via a port, with the second end of the cable configured to connect to an antenna. A processing device may determine a ratio of amplitudes of the parasitic signal over a predefined bandwidth. The processing device may then determine, based on the amplitude of the parasitic signal over the predefined bandwidth, a disconnect status of one or more of the antenna and the cable.
