CDMA Available for Security Systems
As most of you know there are two predominant technologies governing the cellular world in the United States. GSM which runs AT&T, T-Mobile, Corr Wireless and the large majority of the other cellular companies throughout the country. The other is CDMA which is the technology in Verizon and Sprint phones.
To this point the most cost effective cellular device for alarm transmission has been GSM. Recently Uplink released the CDMA30 and CDMA50 which are the CDMA cousins to the 4530 (primary unit only) and the 4550 (primary or backup with its own power supply and battery backup) GSM units. The equipment costs for these units are about the same as the 45xx versions and the monthly service is the same also. This hopefully will allow cell units to be installed in areas where there is limited GSM service.
But be aware that these units are initially programmed for Sprint service and not for Verizon. Even though they are designed to roam to Verizon when there is insufficient Sprint coverage that may not always be the case. Be sure to check the available cellular service before you mount, wire and leave one of these units. If you have any questions please don’t hesitate to contact someone in our technical department.
