Dynamic Cellular Antenna Allocation
The methods and systems herein enable dynamic cellular antenna allocation. Respective statuses of cellular radios are first received. Each of the statuses comprise an idle status or an active status with one or more operating bands. The operating bands are then evaluated for potential interferences between each other and with one or more other radios. Based on the statuses and the potential interferences, a configuration of a switch matrix configured to connect each of a plurality of cellular antennas to either one of the cellular radios or to a termination resistor is determined. The configuration is such that antennas connected to the cellular radios with the potential interferences are physically isolated from each other and any unused cellular antennas are connected to the termination resistor. The configuration is then applied to the switch matrix such that the potential interferences may be mitigated.
