3G Networks are WLAN enabled by Transat.Business Editors & High Tech Writers SOUTHLAKE, Texas--(BUSINESS WIRE)--Aug. 13, 2001 Southlake, Texas Southlake is a city located primarily in the northeastern part of Tarrant County, Texas. A small northernly region of the city is in Denton County, Texas. The population was 21,519 at the 2000 census. based Transat Technologies has announced a solution for integrating 3G services with WLAN See wireless LAN. WLAN - wireless local area network technology. This revolutionary approach to 3G cuts network deployment cost by a factor of ten, and gives cellular operators an additional fast track route to building a 3G subscriber base. Transat has demonstrated how a cellular data subscriber may access the Internet from locations such as airports, offices and cafes at very high speeds (up to 11 Mb/s), while being billed from his cellular account. The cellular operators need only provide inexpensive WLAN base stations on site. No proprietary hardware is used - the WLAN cards and base stations are open standard and vendor independent, as is the software interface, which is fully GSM compliant. The novelty of Transat's approach lies in the use of full GSM protocols and security features, while replacing the standard GSM radio card with a Wireless LAN A local area network that transmits over the air typically in the 2.4 GHz or 5 GHz unlicensed frequency band. It does not require line of sight between sender and receiver. Wireless base stations (access points) are wired to an Ethernet network and transmit a radio frequency over an area card (802.11b/WiFi, 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. , or similar). The WLAN radio connection is made transparent to the GSM protocols, and is invisible to the GSM network. The authentication, authorization, encryption, mobility management and billing are all fully GSM compliant. The communication flows seamlessly into the core network because it is already using the right protocol. In enhancing GSM to take advantage of the cost and performance benefits of WLAN, Transat has closed the gap between 2G, 3G and WLAN standards. With only a small modification, the same software can support 3G over WLAN. The same system can use any type of packet-based communications link, including CDMA. "Here is a solution that combines the flexibility, security and seamless integration An addition of a new application, routine or device that works smoothly with the existing system. It implies that the new feature or program can be installed and used without problems. Contrast with "transparent," which implies that there is no discernible change after installation. of GSM, with the low cost - and blistering performance - of 802.11," according to according to prep. 1.

"There's no fancy hardware - just some software, a WLAN card and a SIM card holder for the PC. We are offering cellular operators rapid deployment of WLAN services without any core network investment." About Transat Technologies, Inc.
