The California High-Speed Rail Authority (CHSRA) received final approval to acquire exclusive rights to the radio spectrum needed to operate future communications systems for its trains.

 

The agreement with Access 700, LLC, a subsidiary of Access Spectrum, LLC, for 44 frequencies covering the lower section of the state, is important for the development of secure and reliable train communication systems. These systems include features such as Positive Train Control. Radio spectrum is also needed to monitor train conditions and diagnostics and to operate security systems along the high-speed rail system.

CHSRA says it purchased Access Spectrum’s Upper 700 MHz A Block spectrum because the signal is clear, not susceptible to interference and not shared with other users. As only authorized parties will have access to these frequencies, they are ideal for secure communication between trains, CHSRA facilities and public safety agencies.

“By obtaining exclusive rights to this spectrum, we will be able to ensure a secure communications network for future high-speed rail operations across California,” said CHSRA Chief Program Manager Frank Vacca.
