Mapletree Strengthens 3G Wireless Offering to OEMs with Adaptive Multirate Vocoder

date: November 13, 2001

Mapletree Networks, a supplier of multi-service network infrastructure equipment for the telecommunications OEM market, announced that it now supports the new Adaptive MultiRate (AMR) vocoding standard as part of its UniPorte Architecture. AMR is a low bandwidth speech coder standard, designed especially for use in next generation 2.5G and 3G wireless networks. AMR allows wireless network operators to support more subscribers within a given bandwidth, an attractive alternative to licensing restricted spectrum and purchasing expensive equipment to expand network capacity.

"AMR vocoding will likely be the standard for the next generation of wireless networks allowing service providers to meet growing demand without additional capacity expenditures," says Will Strauss, of Forward Concepts, an electronics market research and consulting firm. Worldwide use of wireless networks will grow substantially, reaching 1.6 billion subscribers in 2005, up from 472 million in 1999, according to a recent Forward Concepts report.

"When building AMR into our 3G W-CDMA products and softswitch products, we decided to take advantage of Mapletree's engineering support and complete functionality for wireless VoIP media processing," says Pat Chan, Director, Mobile Network at UTStarcom. "This allowed us to quickly add required features without allocating resources to the complexities of vocoder development and implementation. The result is a cost-effective solution that meets the growing traffic demands of our service provider customers, at a time when they will be cautious about spending."
