BAE Systems’ First InterComm System is built upon the Vehicle Communications Assembly (VCA) which is a shoebox-sized smart transceiver that is mounted within the cab or trunk of a first responder vehicle. For the system to work, at least one vehicle from each agency responding to the scene needs to be equipped with a low-cost VCA. When two or more VCA-equipped vehicles are on a scene, such as fire, EMS, and police vehicles the units will automatically detect each other’s presence and establish wireless connection between each other. The First InterComm VCA provides an effective, flexible, and fast solution to mutual-aid radio interoperability. It also makes it easy to send voice transmissions back and forth over IP-based networks. The First InterComm System was reviewed by the Department of Homeland Security and endorsed under the Support Anti-terrorism by Fostering Effective Technologies (SAFETY) Act of 2002. However, even with this “stamp of approval”, agencies within the same jurisdiction must agree to purchase and install VCAs in their vehicles and ensure that such vehicles are always present at mutual-aid situations. This requires money or funds. The Department of Homeland Security may be willing to provide the funds through grants. If the DHS is unable to come through with grant funding, a public campaign could cover the cost. The First InterComm System is seen as a creative and clever solution to the interoperability conundrum.
