1. An electronic device, comprising: a first group of two or more antennas;
a second group of two or more antennas; and
one or more processors, the one or more processors configured to:
establish a wireless cross-link between a first pair of antennas, the first pair comprising one antenna from the first group and one antenna from the second group;
receive information corresponding to the integrity of the wireless cross-link between the first pair of antennas;
determine that the integrity of the wireless cross-link does not meet a predetermined integrity threshold;
establish, in response to the determination that the integrity of the wireless cross-link does not meet the predetermined integrity threshold, an updated wireless cross-link between a second pair of antennas, the second pair comprising one antenna from the first group and one antenna from the second group, with at least one of the antennas in the second pair different from the antennas in the first pair; and
establish the updated wireless cross-link by triggering an adaptive switch on the electronic device, wherein the adaptive switch comprises:
polling each of a plurality of candidate cross-links between antennas from the first group and antennas from the second group in the electronic device to determine a respective measure of integrity; and
selecting the candidate cross-link with a highest measure of integrity as the updated wireless cross-link.
