An exciting new capability will be coming to ALMR with the GTR upgrade project that will help bring additional capacity to ALMR sites across the state. As part of this upgrade, sites will transition from Phase 1 frequency-division multiple access (FDMA) to Phase 2 time-division multiple access (TDMA).

Member organizations are reminded, it will be necessary to reprogram TDMA enabled radios, update firmware (referred to as “flashing”) and program TDMA capable radios, and the eventual life-cycle replacement of non-TDMA capable radios.

Effective immediately, all new radios added to ALMR must be TDMA capable/enabled.
