Another key FEMA disaster response asset is the MERS System. The primary function of MERS is to provide mobile telecommunications, logistics, and operational capabilities for the on-site management of disaster response activities. MERS support falls into three broad areas: (1) Operations - Mobile Emergency Operations Centers, quick reaction support, disaster preparedness (HAZMAT) officers, and MERS security officers. (2) Communications - satellite, multiple radio vans, High Frequency line of sight microwave, land mobile radios, voice, video, and data capabilities, and wide area interoperability. (3) Logistics - fuel, water, HVAC, life support, transportation, and power. MERS provides support required by Federal, State and local responders and can provide prompt and rapid multi-media communications, information processing, logistics, administrative, and operational support. Staged in six strategic locations, one with offshore capabilities, the MERS detachments can concurrently support a large JFO and multiple field operating sites within a disaster area. The telecommunications function is accomplished using a variety of communications transmission systems including satellite, high frequency, and microwave lineof- sight interconnected by fiber optic cables to voice and data switches, local area networks, and desktop devices such as personal computers and telephones. MERS telecommunications assets can be provided for one or multiple locations within a disaster area and can be used to establish or reestablish communications connectivity with the public telecommunications system or Government telecommunications networks. Facilities within a disaster region can be interconnected by MERS assets to enhance emergency communications interoperability and austere facilities can be wired for computer, telephone, and video networks.
