Learn the Alphabet-GSM and GPRS

Deciphering the data transfer alphabet

Some systems have built-in abilities to transmit and receive data from multiple communications devices or technologies. These new systems allow end-users unlimited lifestyle conveniences when coupled with sensors and even video cameras. The trend in the desire and acceptance of these systems will continue and the ease of installation through the use of wireless technology helps the dealer future proof its security installations.

Offering unique security and communications systems is now a way of life for Ron Webb, system designer, Interface Security Systems, Earth City , Mo.

“We try to differentiate ourselves through solutions and applications other than front door and back door installations.” One of the ways Interface is getting ahead, Webb said, is keeping up with the trend of customers getting away from using copper lines. “People do not want to maintain an extra line if they are not using it.” As a result, traditional security transmission to the company's central station had to be rerouted and this is where GSM and GPRS come in as either a backup or primary source of communication. Interface, Webb said, uses cellular and Internet backup on a Honeywell developed product which allows for the various modes of communication to be accommodated in the panel. The panel will instantly transmit the information back to the central station or the end-user depending on the information needing to be relayed.

Webb said one of his customers currently uses their system as an alert for when children arrive home from school—a text is sent directly to the cell phone from the system once the child enters in their code at the home. Another client maintains a vacation home's humidity and temperature levels through sensors. If a problem occurs, service, maintenance or other providers can be let into the home remotely and the residence locked up similarly after they've gone.

Mobile communications help central stations monitor non-critical events, keeping customers in touch remotely and in an instant.


Mobile Alphabet–Defining GSM and GPRS

GSM is a cellular network allowing users to connect to it by searching for cells in its vicinity.

The Global System for Mobile communications (GSM) is estimated to be in use by 80 percent of the global mobile market, according to the GSMA.

GSM networks operate in various frequency ranges to send information from the mobile to the base station.

The General Packet Radio Service (GPRS) is a network for the transmission of data which uses existing GSM network to transmit and receive TCP/IP based data to and from GPRS mobile devices.

The year 2000 marked the launch of the first commercial GPRS services, according to the GSMA. GPRS was added to the GSM cellular network to accommodate increased data capabilities and speed by the system.
