Reducing Wind Noise for Better Two-Way Crisis Communications
THE MOTOROLA SOLUTIONS & USM STORY
Through CREST, Motorola Solutions Malaysia collaborated with Universiti Sains Malaysia (USM), a leading Malaysian public university based in Penang, to innovate a local R&D solution for a global problem in wind noise performance.
Traditional wind porting design requires large geometries but as mission-critical devices get smaller, implementing a good wind noise performance becomes a challenge.
As a result of this collaborative project, the Motorola Solutions-USM R&D team became more proficient in using advanced simulation tools that were set up in the USM’s Vibration Lab. This high-tech equipment, which includes a “wind tunnel” test machine, is still installed in the laboratory for use in other CREST collaborative projects which may involve USM and other CREST members in the future.
The “icing on the cake.” “So, through this engagement, a US patent was filed back in 2014 entitled – Slim Tunnel Wind Port for Communication Devices. It incorporates a slim geometry as part of the patent coverage.”
