The State of Alaska Telecommunications System (SATS) is the backbone network in which ALMR operates.  The network is a highly secure, multi-protocol wide area network that is built using public safety grade equipment.  The network primarily uses microwave connections to connect tower sites and other facilities (e.g. dispatch centers) to the ALMR core equipment.

SATS includes much of the physical infrastructure required for ALMR to operate such as towers, equipment shelters, generators, HVAC, and other needs.  In addition to ALMR, the system carries other two-way radio traffic in areas not served by ALMR, highway call boxes, and other uses that are related to public safety services.
