GE Transportation Selects Summation Research Radios

December 2, 2009

The multi-mode UHF/VHF data radios will be used for both legacy analog and advanced digital needs for GE's LOCOTROL system for railway systems.


MELBOURNE, FL -- Summation Research, Inc. (SRI), has announced a multi-year agreement to supply innovative VHF and UHF data radios to GE Transportation for use with GE's LOCOTROL locomotive distributed power control systems and other rail applications. This agreement continues a successful 10 year relationship between SRI and GE Transportation for high-power data radios deployed with railroads worldwide, provides increased performance and capabilities for new and existing users, and introduces an advancement in narrowband data radio transmission techniques.

Under the agreement Summation Research will supply the STR-1800 Multi-Mode Data Radio, a new generation of its STR family of mobile data radios that provides increased performance and functionality for deployment in legacy 25 KHz and newer 12.5 KHz and 6.25 KHz channels subject to FCC narrowbanding mandates.

SRI is a leading supplier of advanced products for defense, civil, and commercial satellite, aircraft and missile test range, and test & measurement data communications and telemetry applications. SRI has been able to leverage knowledge and experience in these markets to apply proven, reliable military SOQPSK-TG telemetry transmission techniques to commercial Land Mobile Radio (LMR) data communications. Previous industry practices relied on variations of FSK and GMSK techniques to meet narrowbanding 6.25 KHz channel requirements. This breakthrough significantly improves link reliability and performance for applications requiring extended operating ranges over difficult terrain. The radio features an output power level up to 45 Watts and is available for domestic and most international uses supporting analog and digital signals.

"Summation Research is honored to continue our support of GE Transportation", said Tom Drago, Vice President of Business Operations at Summation Research. "A unique ability to apply our knowledge and experience gained in high bandwidth satellite, aircraft, and range telemetry markets to this challenging narrowband railroad telemetry requirement allows SRI to continue a long standing successful business relationship with GE. This breakthrough also provides new methods for small satellite telemetry and communications needs and can improve SCADA and Telemetry connectivity for water, wastewater, oil and gas pipeline, power generation and distribution, refining, and other demanding wireless data communication requirements."

The products to be supplied under this contract are part of a family of transmit and receive Land Mobile Radio, Satellite and Range Telemetry and Communications, and Wireless Sensor Telemetry equipment built by SRI.
