Freescale Semiconductor said it is collaborating with the National Telecommunications and Information Administration’s testing laboratories to determine the interference potential of the various Ultra-Wideband waveforms.
The waveforms include the direct sequence and multi-band orthogonal frequency division multiplex. Freescale, which is a wholly owned subsidiary of Motorola Inc., has the direct sequence protocol, but claims to be working for an industry solution.
Companies behind both protocols have yet to reach an agreement on a standard for the industry. The project will follow four phases, which include UWB signal generation, how to develop measurement methods on emission and how it affects a receiver’s actual measurements of emissions characteristics and how digital and analog downlink receivers react to interference.
“The data we receive in the initial stages of the project will provide important information to the IEEE voting members prior to the July meeting in Portland, Ore.,” said Martin Rofheart, director of UWB operations for Freescale Semiconductor.
