Various arrangements for mapping antennas to transceivers are presented. A plurality of antennas may be present. Each antenna of the plurality of antennas may be configured to communicate using different radio technologies. A plurality of transceivers may be present. At least some of the transceivers of the plurality of transceivers may be configured to utilize different radio technologies. A selector circuit may be present that is configured, based on input from a processor, to map each antenna of the plurality of antennas with each transceiver of the plurality of transceivers. The processor may be configured to control which antennas of the plurality of antennas are mapped to which transceiver of the plurality of transceivers. Touch sensors may be used to determine which antenna or antennas are likely to serve as effective electromagnetic transducers. Signal-to-noise measurements may be used to determine when to modify an antenna mapping.
