Abstract

A subassembly for an integrated wireless module is provided. The subassembly includes an integrated-wireless-module input/output (I/O) connector, a modem controller; at least one internal antenna, and at least two modem connectors communicatively coupled to the modem controller, the modem connectors configured to interface with at least two modems. The modem controller digitally selects to one of: communicatively couple one of the at least two modem connectors to one of the at least one internal antenna; communicatively couple one of the at least two modem connectors to the integrated-wireless-module I/O connector; and communicatively couple a first one of the at least two modem connectors to one of the at least one internal antenna and communicatively couple a second one of the at least two modem connectors to the integrated-wireless-module I/O connector.
