In the absence of an affirmative extension from the FCC, the AMPS sunset will occur as scheduled. The largest cellular carriers (providing service to most of the country) have publicly reported to the FCC that they will shut down their AMPS service shortly after the scheduled February 18, 2008 "Sunset" date. In fact, there have been several reports of AMPS network deterioration.

What this means to the alarm industry is that whatever cellular backup or primary units (both direct analog and control channel versions) an alarm company may had previously installed will no longer work once the cellular carrier shuts down its AMPS system, after February 18, 2008. Some dealers are under the misconception that their installed cellular units are "digital" and they are not affected by this sunset issue.

Unless you have specifically installed GSM celluar radios, your digital units which use the control channel of the analog (AMPS) service will stop functioning.
