Anite Test Technology Increases Performance of Wireless Networks; Adaptive Multi-Rate Test Cases from Anite Optimize Network Capacity for Voice Traffic.Business Editors & High-Tech Writers FLEET, HAMPSHIRE, U.K.--(BUSINESS WIRE)--Dec. 9, 2002 Anite, a leading provider of test and measurement technology for the wireless communications wireless communications System using radio-frequency, infrared, microwave, or other types of electromagnetic or acoustic waves in place of wires, cables, or fibre optics to transmit signals or data. industry, today announced the availability of test cases used for the certification of Adaptive Multi-Rate (AMR (1) (Adaptive Multi-Rate) A variable rate speech codec selected by the 3GPP for the 3G evolution of the GSM cellphone system (WCDMA). Using the Algebraic CELP (ACELP) compression technology, AMR provides toll quality sound at transmission rates from 4.75 to 12. ) technology in mobile phones and other wireless devices. AMR, a speech-related technology set forth by the Third-Generation Partnership Project (3GPP GPP Government Performance Project GPP General Purpose Processor GPP General Physical Preparedness GPP Gambian People's Party GPP Good Pharmacy Practice GPP Gross Primary Productivity GPP Green Procurement Program GPP Generic Packetized Protocol ), is designed to improve the perceived speech quality of wireless networks through adaptive coding Adaptive coding refers to variants of entropy encoding methods of lossless data compression. They are particularly suited to streaming data, as they adapt to localized changes in the characteristics of the data, and don't require a first pass over the data to calculate a schemes. Operators will use AMR to improve the speech quality by trading audio quality against the integrity of the radio link. The new test cases from Anite allow operators and handset The part of the telephone that contains the speaker and the microphone. On a desktop phone, the part you hold in your hand is the handset.

"Anite is the only provider of test and measurement technology offering AMR test cases," said Bob Morley, Product Manager, Anite. "AMR is critical in enabling increased voice quality on existing wireless networks. Until operators can complete the transition from 2G and 2.5G services to higher-bandwidth 3G networks, they will rely on AMR technology for efficient management of their constrained con·strain tr.v. con·strained, con·strain·ing, con·strains 1.

Anite continues to lead in the development of testing solutions that meet the needs of an evolving wireless industry." AMR is a circuit-switched Phase II+ (2.5G) technology that allows a terminal to adapt its coding scheme -- its connection to the wireless network -- based on location. AMR utilizes full-rate and half-rate coding schemes, therefore making best use of available bandwidth for voice-only calls. Implemented worldwide, AMR is a pervasive pervasive, adj indicates that a condition permeates the entire development of the individual. technology that is also forward compatible with 3G systems. AMR test cases from Anite ensure the technology operates as intended in 2G, 2.5G and 3G mobile phones and terminals. Availability AMR test cases are available today from Anite. AMR test cases from Anite can be used in conjunction with the company's SAT or SAT+ wireless testing platforms.
