Applications

Interoperability

The RadioGrid RG-4 is designed with interoperability applications in mind. A RG-4 can be installed at multiple radio sites, or linked to radio sites. Commands entered from the management console, or as DTMF over the air, can link any site to any other site, as long as IP connectivity to the end node radio gateway is available. Systems can be put in place and activated for interoperability tests or crisis communications.

Remote Access

Remote access to radios or repeaters is simple with RG-4. A PC-based "soft radio" or "soft phone" can allow authorized users to listen and talk to the connected system from anywhere that internet access is available.

Telephone Interconnect

Because the RG-4 is based on Asterisk, the world's leading open-source PBX, telephony integration is built in. Radio users can initiate and receive telephone calls through an internet telephony provider. In high-density radio sites, the cost of multiple telephone lines can be prohibitive, but one broadband internet connection can allow many simultaneous telephone calls to be carried at a significantly reduced cost.

Wireline Dispatch

Just like the high cost of dial tone can be avoided, many wireline dispatch circuits can be consolidated from multiple "dry pairs" to a single broadband internet connection, offering significant savings.

Amateur Radio Repeater Linking

Amateur Radio Operators can use the RG-4 Radio Gateway as an Internet-enabled repeater controller. Repeater users with proper authorization can enter touch-tone digits to link to one or more remote repeaters. The RG-4 is compatible with the All Star Link, which boasts more than 100 connected systems.

Frequency-Agile Remote Base

The RG-4 supports frequency-agile radios, for instance the popular Icom IC-706 Mk II G and the Yaesu FT-897. Authorized users can access these radios as a remote base from any local RG-4 port, any remote RG-4 port, PC-based "soft radios" and even telephones, if the host RG-4 is configured to use a internet telephony provider.

Unlimited Opportunities

Because the RG-4 is based on open-source Linux and open-source Asterisk, the opportunities for expansion are boundless. Users can write their own applications to add features to the RG-4
