Ericsson Breaks Peak Data Speed Record on T-Mobile's GSM EDGE Network

7/6/2004 - Ericsson has achieved world record peak data speed - 235.6 kbit/s across the radio interface - on T-Mobile's EDGE (Enhanced Data Rates for Global Evolution) network in Hungary. Performance, functionality and download capacity of the network was measured for two weeks in Budapest.

T-Mobile Hungary and Ericsson successfully demonstrated the high-speed mobile data possibilities with EDGE technology. The aim of the application level measurements was to assess the robustness and outstanding performance of EDGE delivered by Ericsson in a live radio environment. The measurements were performed according to the Ericsson test description for active GPRS/EDGE end-to-end performance testing at pre-selected measurement locations.

EDGE service has been commercially available in T-Mobile's network in Hungary since November, 2003. In addition to the world record of 235.6 kbit/s peak download speed the test also proved that EDGE benefits from T-Mobile's well-planned and optimized radio network. However, the current commercially available network configuration of T-Mobile Hungary supports only 100 kbit/s peak data rates.

EDGE is a natural complement to 3G WCDMA technology providing high-speed mobile data services in rural as well as urban areas.

Ericsson is shaping the future of Mobile and Broadband Internet communications through its continuous technology leadership. Providing innovative solutions in more than 140 countries, Ericsson is helping to create the most powerful communication companies in the world.

About the measurements / technical description
EDGE enables high-speed data in GSM/GPRS networks and 4-timeslot EDGE can support up to 236.8 kbit/s over the radio interface. The measurements were performed using the standard commercially available Ericsson equipment.

A peak over the air bit rate of 235.6 kbit/s was measured during download of data files using the file transfer protocol FTP in combination with EDGE. The related measurements of large files averaged 213.5 kbps including TCP/IP effects and overhead. The measured result is in line with expectations also considering the capability of the terminals currently on the market. Terminals with Rel'4 functionality will further improve the performance.
