CES Wireless Technologies Announces Expanded Compatibility with GSM and GPRS for Truly Global Applications.Business Editors/Technology Writers WINTER PARK, Fla.--(BUSINESS WIRE)--March 29, 2001 CES Wireless Technologies announced that it has fully tested and certified See certification. its mobile and base station equipment and software for GSM (Global System for Mobile Communications) A digital cellular phone technology based on TDMA that is the predominant system in Europe, but also used worldwide. Developed in the 1980s, GSM was first deployed in seven European countries in 1992. applications in addition to the company's already wide range of interfaces. "This adds a more global application as well as higher speed, highly secure and efficient data transmission," noted Pat Lohan, President. "We have maintained our technology leadership through constantly upgrading as the wireless industry evolves, but not at the expense of our customer's systems." Lohan continued, "That demands that while we are very up-to-date, we maintain our compatibility with existing or `legacy' systems as well." CES has tested the applications both in the US and Europe and incorporated them into the TRK-240(TM), GPS-210(TM), and GPS-150(TM) mobile units and base software in POWER-trak(TM) and QUICK-trak(TM). The integrated systems are able to communicate via GSM, PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. , TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). and iDEN in addition to satellite or two-way trunking See port aggregation. systems. This array provides a versatile system for Fleet Management and commerce. The GSM interface is used throughout Europe and most of the rest of the world but has been slow to gain applications in the US. GSM is available in the US through the VoiceStream and Western Wireless networks and AT&T has announced that they will be adding this functionality to their system over the next few years. GSM is now available in nearly every US city and is expanding rapidly due to its compatibility with other systems worldwide. GSM and the related newer data application - GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. - are expected to become the primary standards for cellular voice and data in the US over the next three years. CES Wireless products are available directly from the company or through its dealer network and the Motorola(TM) radio dealer network under a program recently announced by both companies. CES Wireless' introduction of QUICK-trak(TM) made CES systems more affordable to small fleets and the internet based FLEET-link(TM) system combined with a soon-to-be-released cargo tracking option will enable even one vehicle `owner-operators' to afford and access the quality of CES Wireless systems. |
