The ICRI (Incident Commanders' Radio Interface) expands its usefulness beyond providing quick and easy on-site, cross-band/cross-platform interoperability for all radio devices, with the addition of it's Extension Cable/Reel, EC/R. The Extension Cable/Reel moves an ICRI-connected radio into a poor RF coverage area---in a mall, high rise, basement, tunnel---providing improved radio signals for first responders where otherwise they would have marginal or even no communications with command and support personnel outside.
