Nokia Siemens Networks (NSN), Cisco and public sector technology company Harris have completed initial testing of the public safety LTE broadband network in the US.

The companies are supporting the aim of the US First Responder Network Authority (FirstNet) to create a nationwide, multi-vendor public safety network for real-time voice, video and data communication for emergency services.

The network architecture conformance and interoperability testing was completed at the Department of Commerce Laboratories in Boulder, Colorado. NSN supplied the LTE radio access network component for the network.

FirstNet is an independent authority within the National Telecommunications and Information Administeration (NTIA) that is overseeing the development of the public safety broadband network.

"The PSCR phase 3 testing accomplishment and the successful multi-vendor implementation of the LTE solution at the RNC highlight the viability of the long-term goal to deploy a similar nationwide system," said NSN's head of public safety, Bob Fennelly.
