GPS Technology And Acoustic Apps Enhance Mobile Environments

The company’s indoor-capable assisted Global Positioning System (A-GPS) technology is said to reduce the total bill of material (BOM) costs for handset makers by a factor of two to three. And implementation of technology on the network side is claimed to require minimal investments. The technology mates software with the Nexperia cellular multimedia baseband processor and UAF1572H GPS front-end, billed as the industry’s first GPS front-end that does not need any external SAW filter. The software portion of the package, called the LifeVibes family of acoustical software, includes Noise Void, Hands Free, and Voice Clarity applications. They are designed to eliminate background noise and echo while improving speech quality in mobile phones and portable multimedia devices. Noise Void removes background noise using a two-microphone spatial filter. It reportedly features better stationary and non-stationary noise reduction than a single microphone setup. Hands Free, reportedly the industry's first true full-duplex echo canceller, eliminates stationary noise caused by external devices, such as fans, engines and air conditioners. Particularly for teleconferencing, the Voice Clarity improves speech quality by enhancing all voice types with any loudspeaker or ear piece. Price for the A-GPS, including the GPS UAF1572H RF IC and license for the baseband software, is $5 each in high volume quantities. Noise Void is priced at $330,000 for the initial license with a royalty fee of $0.90 each/100,000 and Hands Free is $110,000 for the license with a royalty fee of $0.55 each/100,000. Voice Clarity costs $220,000 for the license with a royalty fee of $0.33 per each/100,000. PHILIPS SEMICONDUCTORS, Sunnyvale, CA. (800) 234-7381.
