RC-9661 Remote Control System

RC-9661 Remote Control System provides mobility for Software Defined Networking Radio (SDNR) users in tactical field by eliminating the necessity of being in same place with the radio. It supports remote control of up to 3 radios and remote audio/data communication, one each at the same time, over 2-wire field cable that can be 3 kilometers in maximum length. It is possible to select different radios, one for remote control, one for remote voice and one for remote data. Furthermore, users can listen all connected radios at the same time if desired. 

Remote Control System consists of a Remote Control Unit (RCU) to be used for mobility and a Local Communication Unit (LCU) to be located close to the radios. RCU and LCU send/receive information between each other over a basic rate ISDN (2B+D) channel, total of 144 kbps in bandwidth, with a customized protocol implementation.

Remote Control System has additional features besides remote operation of radios such that it supports full-duplex intercom calls between RCU and LCU operators. In addition to that, RCU has line interface for making connection to the terrestrial telephony network and conference calls are possible with the LCU operator. So, RCU is the single device for handling different communication needs in tactical area.

Voice Communication

RC-9661 Remote Control System is capable of maintaining voice communication features of the connected radios at remote location. RCU and radio have same audio interfaces so that audio devices and systems like headphone, handset, external speaker, etc. are used in same way once the connection is established between them. Voice is transmitted as PCM encoded in 64kbps bandwidth between RCU and LCU. 

RCU operator can select single radio for voice communication such that this selection can be easily changed with predefined shortcuts in runtime whenever it is required. Additionally, it is possible to listen and receive voice from all connected radios, which might be important and advantageous in tactical area. 

Data Communication

RC-9661 Remote Control System is capable of maintaining IP data communication of the connected radios at remote location. RCU and radio have same IP/data interfaces so that ethernet enabled devices are used in same way once the connection is established between them.

RC-9661 Remote Control System behaves transparent to the Ethernet packets between two ends as much like an L2 device during transmission of data packets. Data is transmitted as MAC frames in 64 kbps bandwidth between RCU and LCU. It should be noted that Ethernet is highly faster way of communication compared to ISDN channels. So, RC-9661 Remote Control System may throttle data bandwidth to 64 kbps during high Ethernet data traffic.

RCU operator can select single radio for data communication such that this selection can be easily changed with predefined shortcuts in runtime whenever it is required.

Remote Radio Control

RC-9661 Remote Control System is capable of controlling connected radios for remote operation. Once the connection is established between them, it is possible to display selected radio screen on RCU without any change on pixels. Furthermore, all keypad actions occured in RCU are transmitted to the selected radio and display is updated in response. So, operator is supposed to use RCU just like using the radio itself.
