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.
Claims20
A Radio over Internet Protocol (RoIP) expansion device providing radio ports for a RoIP system, the RoIP expansion device comprising:
- a Universal Serial Bus (USB) input configured to plug into a USB port of a host device and connect to the RoIP expansion device to a USB bus of the host device;
- a plurality of radio ports, each radio port of the plurality of radio ports configured to connect with a respective radio of a radio network;
- a microcontroller communicatively coupled with the plurality of radio ports and the USB input, the microcontroller configured to:
- associate each radio port of the plurality of radio ports with an audio device connected to the USB bus;
- relay audio communication between the plurality of radio ports and the host device via the USB bus;
- and
- communicate signaling information for each of the radio ports via a Human Interface Device (HID) connection.
A method of providing radio ports with a Radio over Internet Protocol (RoIP) expansion device, the method comprising:
- associating a first radio port of a plurality of radio ports of the RoIP expansion device with an audio device connected to a Universal Serial Bus (USB) bus of a host device with which the RoIP expansion device is connected;
- subsequent to associating the first radio port with an audio device connected to the USB bus of the host device, relaying audio communication, via the USB bus, between a radio of a radio network and the host device, wherein the radio is connected with the RoIP expansion device at the first radio port;
- and
- communicating signaling information for the first radio port via a Human Interface Device (HID) connection.
A non-transitory computer-readable medium having instructions embedded thereon for providing radio ports with a Radio over Internet Protocol (RoIP) expansion device, wherein the instructions, when executed by one or more processors, cause the one or more processors to:
- associate a first radio port of a plurality of radio ports of the RoIP expansion device with an audio device connected to a Universal Serial Bus (USB) bus of a host device with which the RoIP expansion device is connected;
- subsequent to associating the first radio port with an audio device connected to the USB bus of the host device, relay audio communication, via the USB bus, between a radio of a radio network and the host device, wherein the radio is connected with the RoIP expansion device at the first radio port;
- and
- communicate signaling information for the first radio port via a Human Interface Device (HID) connection.
