Service and installation for both residential and commercial properties
Starting in 2011, in an effort to increase service levels to their consumer cell phone customers, cellular carriers will start to make their preferred frequencies 3G/4G only. The process is called spectrum harvesting. Similar to how semis must stay in the highway’s far right lanes because of their slower speeds, 2G devices will not be allowed on the best frequencies. For 2G devices this will be a noticeable shift. If they were installed based on the coverage provided by the preferred frequencies, their signal levels will drop as they are forced onto the inferior, shallow penetrating frequencies still supporting 2G. This restriction will not occur all at once. It will appear sporadically across the country and when it does, only 3G/4G devices will be oblivious to the change.
Finally, after December 31, 2016, when the 2G Sunset is complete, it will be just like the Analog Sunset. Anything using 2G will stop working overnight. Only 3G/4G will work from that day forward.
You’ll recall that cellular carriers deploy their networks in two frequency bands: a preferred band with deep building penetration (850 MHz) and another band with shallow building penetration (1900 MHz). Prior to 2011, cellular carriers equally spread 2G and 3G/4G across both bands like a highway that allows all cars to drive in all lanes.
Cut phone and internet lines are a threat of the past. Alarm.com's safer cellular alarm systems are not affected by damaged phone or internet lines and provide uninterrupted protection. Unlike all other interactive cell units, Alarm.com offers cell units on all three major carriers AT&T, T-MOBILE, and the only one to offer the option of the VERIZON network.
Here is why you should upgrade your radio ahead of time! As the 2G Sunset approaches, spectrum harvesting by the cellular carriers will dramatically alter the performance of 2G hardware based on their allocation of cellular frequencies. To comprehend the effect, the only characteristic a security dealer needs to understand is that lower frequencies penetrate buildings better than higher ones. In the U.S., the lower frequency band is at 850 MHz and the higher band is at 1900 MHz. Most cellular devices installed inside homes and businesses rely on the deep penetrating 850 MHz band to connect to neighboring cell towers.
Please contact Home Security Systems prior to changing your phone service. It is highly recommended that if your security system is monitored via your phone service that you retain your analog phone line for highest reliability and best results.
If so, we have other options available for you. Radio monitoring – Is the most common and best alternative to your phone line and offers a higher level of security because the communication path is wireless and not venerable to a burglar cutting the phone line on the exterior of the building.
“Prior to your AT&T U-verse Voice installation, AT&T strongly recommends that you notify your alarm company of your switch to AT&T U-verse Voice service and your scheduled AT&T U-verse installation date, in order for your alarm company to test and check the status of your alarm system with you once installation is complete. If there are any issues, those can be addressed directly with your alarm service provider.” (Source AT&T) please visit at&t for more info.
