[Tektronix announces its cooperation with Siemens in a test of GPRS data services.]
Beaverton, Ore. -- "Tektronix, Inc. (NYSE: TEK) today announced that it participated with Siemens in a demonstration of a complete GPRS (General Packet Radio Service) system for extending the current GSM mobile phone generation, today's most widely used mobile phone standard. Tektronix' protocol testers were used to support the test of the system, which was able to send e-mails, wireless access protocol (WAP) services, news-Ticker information, and Short Messages Services (SMS) to numerous German mobile phone numbers. The test also performed telemetry, including the remote control of a washing machine.
"The Siemens demonstrations, presented for the first time at Telecom 99 in Geneva, made use of the Tektronix K1297 and K1205 protocol testers. The protocol tester K1297 from Tektronix was used to simulate and evaluate GPRS data services for GSM networks. In addition to the K1297, the K1205 was also used to monitor functionality.
"GPRS is significantly used in the transition from today's circuit-switched data services to rapid packet-switched services, expected to be introduced to GSM networks within the next few years. The new technology promotes the dissemination of additional mobile services; lowering the costs associated transmission, while increasing data transfer rates in mobile phone networks from 9.6 kilobits per second to over 100 kilobits per second. Since up to eight data streams can be transmitted in parallel, data rates of up to 384 kilobits per second are theoretically possible. These high transfer rates are useful for applications, such as e-mail, mobile Internet applications, multimedia and video conferencing.
"The introduction of GPRS will lead to a substantial increase in subscriber numbers and make the use of data and Internet services via mobile phone considerably more attractive. However, with this increase in load, existing air interfaces and radio channels will be exposed to a dynamic demand. This will drive the use of measurement systems that must be used to target problem zones reliably. Tektronix has developed a whole series of such measurement systems to support the GSM standard.
