TTA Specification Delivers Greater Consistency, Audio Quality and Reliability for First-Responder Radio Communications in North America

Source: Read about the problems associated with the old system, the changes brought about by the new specification, and its benefits for public-safety communications in North America.

In 2018, one of the leading OEMs of critical communication equipment in North America changed its specification for the Tower Top Amplifiers (TTAs) installed in critical communications network base stations. This has now become their only specification of TTA available for new or replacement installations throughout the land mobile radio (LMR) network in North America. The rationale for the switch to this new specification was not widely publicised, and there remains limited understanding in the market about the benefits of the change.

Filtronic was instrumental in developing a TTA product to meet the new specification. Working closely with the OEM gave the company a clear understanding of the thinking behind the new specification, the advantages it offers to radio system installers, and the improvements in LMR communications it brings to first responders.

In this" Business Inside" section on the P25 pages of this website, Filtronic outlines the background to the specification change, the problems associated with the old system, the changes brought about by the new specification, and its benefits for public-safety communications in North America.
