Spirent Communications plc (LSE:SPT), a provider of test, assurance, and analytics solutions for next-generation devices and networks, has announced critical findings from its LTE Device Speech Intelligibility Benchmark Analysis, the company said.
The findings in the report show that phrase misunderstandings can occur in mission-critical communications scenarios up to almost 50 percent of the time, even when using devices that are marketed specifically for use by the public safety community.
As public safety networks transition to PS-LTE (Public Safety LTE), more handsets are entering the market. Spirent conducted testing of a representative sample of these handsets in its Maryland-based Performance Center – a world-class testing facility that specializes in evaluating the communications performance of voice, video and data devices. As part of the test process, the company evaluated speech intelligibility in four commercially available devices.
Testing emulated use within a quiet environment, followed by six emulated first-responder noise environments including a nightclub, emergency siren and a fire-rescue situation utilizing a saw.
