Radio Over Internet Protocol (RoIP) Expansion Device

Abstract:

A RoIP expansion device can be used to expand the amount of available radio ports at a RoIP gateway. The RoIP expansion device includes a microcontroller for relaying audio and signaling information between the USB bus of a host device (e.g., a RoIP gateway device or computer) and a plurality of radio ports. According to some embodiments, the RoIP expansion device may include serial and/or general-purpose input/output (GPIO) ports to provide additional functionality.
