Abstract
A reconfigurable wireless modem adapter is provided. The reconfigurable wireless modem adapter includes a control board and a radio frequency switch. The control board includes at least two user-data interfaces for respective at least two modems, the modems including at least one diversity/multiple-input-multiple-output (MIMO) modem. The control board is configured to communicatively couple to at least one onboard system in a vehicle and to activate one of the at least one diversity/MIMO modem interfaced to one of the at least two user-data interfaces. The radio frequency switch is communicatively coupled to the control board via a modem-select interface and the selected one of the at least one diversity/MIMO modem. The radio frequency switch communicatively couples one of at least one diversity/MIMO antenna on the vehicle to the selected one of the at least one diversity/MIMO modem based on a control signal.
