Advanced Mobile Phone System (AMPS)
The Federal Communications Commission (FCC) on August 8, 2002 established a sunset date of February 2008 for the requirement that cellular carriers provide analog mobile phone service (AMPS). This sunset date is significant for alarm companies that utilize cell phone-based radios for relaying alarm signals. Once the sunset date has passed, cellular carriers may terminate AMPS service to the public, thereby stranding cellular alarm radios that rely on AMPS technology.
