TETRA - TErrestrial TRunked RAdio

The TETRA standard has been unlocking the power of communication for industrial and mission critical clients since 1997. This unparalleled technology provides businesses and government agencies with unrivaled wireless, secure, mobile communications.


Nielson Networks is proud to bring this technology to the United States. We ran a TETRA Pilot here in Green Bay for over 2 years, with several groups visiting us to try the system for themselves. We also put TETRA on wheels, by bringing a working TETRA system to customers to try out.


Please contact us for a webinar, or arrange visit, to try the system out for yourself!
