Bombardier Transportation has completed tests to operate its several mass transit and mainline rail control solutions with the 4G Long-Term Evolution (LTE) standard for wireless data communications.

The tests were carried out in collaboration with major suppliers Huawei, Nokia, Ericsson, and ZTE.

Technical assessments were carried out in compliance with industry Quality of Service (QoS) requirements to ensure the transmission of critical signalling information, as well as other wireless communication with the train.

The LTE standard not only supports high-speeds and capacity for wireless data transmission networks but also allows consolidating delivery of multi-service traffic into a single wireless network.

Bombardier's transportation rail control solutions division president Peter Cedervall said: “Thanks to its high capacity, LTE can provide a broad range of services to the public and various infrastructure operators.

“It offers an effective, comprehensive and economical solution for city planners and national infrastructure decision makers.

"The LTE standard supports high-speeds and capacity for wireless data transmission networks."

“Our recent, successful multi-service tests with a number of telecommunications networking partners will ensure we continue to offer our customers around the world reliable, proven and advanced solutions as they respond to new requirements.”

Railway operators use LTE standard to facilitate ground-to-train voice and data communications, along with integrating the transfer of safety-critical signalling, passenger information system, closed-circuit television, and onboard internet services into one network.

Operating rail control solutions with LTE standard facilitates improved system stability as well as data encryption and security.

The range of rail control solutions of Bombardier include Cityflo mass transit solutions ranging from manual and fully automatic to communications-based systems, and Interflo mainline solutions ranging from conventional systems to European Rail Traffic Management System (ERTMS) Level III systems to industrial applications.
