FCC Authorizes 700 MHz Air-to-Ground for Maryland (8/21/12)
The FCC’s Public Safety and Homeland Security Bureau (PSHSB) granted a petition for waiver of the commission’s rules filed by the state of Maryland requesting authorization to use 700 MHz narrowband secondary trunking channels for air-to-ground interoperable radio communications.
As part of the waiver, the commission required Maryland to comply with the operational and technical limitations specified in Section 90.423 of its rules, which specifies that Maryland’s air-to-ground operations must accept interference from other licensees and must not cause harmful interference to other licensees.
Maryland seeks to use the 700 MHz narrowband secondary trunking channels for air-to-ground interoperable communications in conjunction with its Maryland First Responders Interoperable Radio System Team (Maryland FiRST) system, a statewide intergovernmental 700 MHz public safety narrowband network, and the Maryland State Police-Maryland Institute for Emergency Medical Services Systems (MSP-MIEMSS) emergency medical system. Specifically, Maryland proposes to use the secondary trunking channels to enable first responder aircraft, such as rescue helicopters operated by the Maryland State Police (MSP), to communicate with ground-based police and EMS vehicles using the Maryland FiRST system.
