IFR Announces GPRS Test System for Service Centers; 2935 with PhoneTest Allows Seamless Transition to GPRS Testing.Business Editors, Hi-Tech Writers WICHITA, Kan.--(BUSINESS WIRE)--Feb. 11, 2002 IFR IFR abbr. instrument flight rules Systems, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :IFRS IFRS International Financial Reporting Standard(s) IFRS Inter Frame Relay Service IFRS Indiana Facilities Registry System ) today announced GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. (General Packet Radio Service) handset testing capability aimed at repair centers that service and maintain GPRS mobile handsets. Designed specifically for service operations, the 2935 radio test system offers service organizations a convenient way to upgrade their workshop's testing capability. With GPRS-enabled handset sales expected to grow from $10 million worldwide in 2001 to $280 million in 2005, service organizations must upgrade their testing capabilities to keep up with the rapid adoption of GPRS. The 2935 system, which includes the new GPRS firmware A category of memory chips that hold their content without electrical power. Firmware includes flash, ROM, PROM, EPROM and EEPROM technologies. When holding program instructions, firmware can be thought of as "hard software." See flash memory, ROM, PROM, EPROM, EEPROM and FOTA. option coupled with IFR's PhoneTest management software, provides all the necessary signaling, test and analysis capability to quickly characterize transmitter and receiver performance of GPRS handsets. The new GPRS firmware module includes CS1 and CS4 channel coding A way of encoding data in a communications channel that adds patterns of redundancy into the transmission path in order to lower the error rate. Such methods are widely used in wireless communications.

Workshops easily transition from GSM to GPRS testing with the 2935 The 2935 has been widely adopted by the service industry for GSM testing. The 2935's new GPRS test module now allows full testing of GPRS handsets. By using the "always on" feature of GPRS, combined with innovative testing functions developed by IFR, the 2935 allows workshop technicians to quickly change from GSM to GPRS test modes. By allowing the GPRS test parameters to differ from the GSM parameters, the 2935 and IFR's PhoneTest software enable instant changeover from GSM to GPRS when used in manual mode. No additional parameters are required. Clicking on the GPRS button in the PhoneTest menu transitions the tests automatically. The 2935 GPRS option provides extensive test features, including mobile-initiated GPRS attach sequence, cell transfer and control channel configuration for GPRS parameters. The 2935 GPRS option also offers fast BER testing using ETSI-specified BER Test Mode B with a user-defined failure percentage and a number of samples, as well as ETSI-defined and user-configurable BLER tests. The 2935 can establish "true" sensitivity by testing both BER and BLER sensitivity using the extremes of the four available channel coding schemes -- CS1, which has channel correction for robust communication, and CS4, with no channel correction for maximum data rates. About the 2935 GSM radio test system and PhoneTest software The 2935 is a high-speed test head. It is combined with IFR's Windows(R)-based PhoneTest software to meet the ever-increasing demands of mobile handset repair workshops, where the key requirements are speed of test, flexibility and low cost of ownership. The 2935 supports both GPRS and GSM testing. The 2935 test system has all the protocol control necessary to carry out both GPRS and GSM transmitter and receiver measurements. PhoneTest provides the user interface for automatic and manual control of the 2935 high-speed test head. PhoneTest allows the storage and retrieval of test and repair information, generation of warranty claim forms, repair hints based on the analysis of past repairs, management reporting, and repair process tracking. PhoneTest also provides interchange of data with existing computer systems. The recommended minimum system for running PhoneTest is a PC with 166 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. Pentium(R)-equivalent processor, 64 Mbyte RAM, serial port and Microsoft Windows See Windows.

Widely criticised for being too slow (hence "Windoze", "Microsloth Windows") on the machines available then. 95, 98 or NT. Workshop management software can be added to streamline repair process In addition to PhoneTest, IFR also offers a workshop management software module to streamline the entire repair process. With the workshop management option, PhoneTest not only acts as the user interface for the 2935, but also integrates results into the user's repair system, increasing throughput and reducing costs. The management option provides the traceability tools demanded by manufacturers and retailers when awarding service contracts. Workshop management users reduce errors that result from repetitive manual entries, ensure that only good handsets leave the workshop, provide warranty paperwork for each manufacturer, trace all activity for audit purposes, communicate with existing management system databases for automatic updating of job status and provide workshop management reports. Price and availability The 2935 GSM radio test system with PhoneTest is priced at U.S. $11,394. The GPRS Test Option 01 is priced at U.S. $4,000. Field upgrades are available for existing customers with 2935 units that have had the required RAM upgrade installed previously. For 2935 units that need the RAM upgrade, it is priced at U.S. $395. The cost of the RAM upgrade can be offset against the cost of the GPRS upgrade. Units must be returned to an authorized IFR service facility to have the RAM installed.
