GE Transportation Systems chooses Summation Research for high-power LMR Data Compatible Radios

Melbourne, Fla, October 16, 2004 - Summation Research, Inc., a provider of advanced equipment for data communications, wireless, supervisory control and data acquisition (SCADA), satellite and terrestrial telemetry, and test equipment markets, today announced the extension of a multi-year agreement to supply VHF and UHF data compatible radios to GE Transportation Systems for their “Locotrol” locomotive control systems. This extension continues the successful relationship established in 2000 and includes data radios deployed for rail systems worldwide.

The radios are designed for applications requiring extremely ruggedized packaging to provide transmission of data in licensed VHF and UHF frequency bands. The units feature high power transmit capability for applications requiring extended operating ranges and high reliability. The radio is available for both domestic and most international uses.

Having already supplied in excess of 5000 units to GE, the contract extension incorporates a next generation design of the radios, thus assuring product continuity through the end of the decade. “Summation Research is proud to prolong our vendor relationship with GE Transportation Systems”, said Tom Drago, Vice President of Business Operations at Summation Research. “This extension allows us to upgrade the designs to insure the continuation of what has proven to date to be a mutually beneficial, long standing business relationship.”
