Comarco Wireless Technologies Announces the Results of Its Cellular Quality of Service Survey for the Los Angeles Market.IRVINE, Calif.--(BUSINESS WIRE)--Aug. 23, 1999-- Comarco Wireless Technologies Inc. (Nasdaq:CMRO CMRO Current Medical Research and Opinion (journal) CMRO Concerned Motorcycle Riders of Ohio CMRO Canadian Mud Racing Organization CMRO Certified Medical Review Officer CMRO Complex Maintenance, Repair & Overhaul ) Monday announced Quality of Service (QoS) survey results for all of the wireless operators in the Los Angeles Los Angeles (lôs ăn`jələs, lŏs, ăn`jəlēz'), city (1990 pop. 3,485,398), seat of Los Angeles co., S Calif.; inc. 1850. market. The survey evaluated networks operated by AT&T, Sprint PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. , Pacific Bell Mobile Services, AirTouch and Nextel. Network quality issues evaluated in the survey included network accessibility ("blocked calls"), call retention ("drops") and average call quality. The Comarco Wireless survey covered the entire Los Angeles metropolitan geography including Los Angeles, Orange, Riverside and San Bernardino San Bernardino, city, United States San Bernardino (săn bûr'nədē`nō), city (1990 pop. 164,164), seat of San Bernardino co., S Calif., at the foot of the San Bernardino Mts.; inc. 1854. counties. Nearly 7,000 miles of freeways, major streets and roads were covered during the evaluation, with more than 5,000 calls analyzed an·a·lyze tr.v. an·a·lyzed, an·a·lyz·ing, an·a·lyz·es 1.

It is a subjective measurement that is derived entirely by people listening to the calls and scoring the results from : Mean Opinion Score of audio quality. Scale ranges from one to five, five being best. Recent articles published widely in the financial and industry press have noted that wireless operators are currently experiencing significant quality of service perception problems resulting from increases in cellular usage due to new lower pricing programs. "CWT cwt 112 pounds avoirdupois weight. independent market research of cellular users' quality concerns has echoed the sentiment of these recent articles. Our syndicated QoS survey efforts should offer timely feedback on system performance and assist network operators in pinpointing important areas for potential improvement," stated Michael Burdiek, CWT senior vice president. Data was collected for the Los Angeles survey with baseLINE, the latest generation quality benchmarking system developed by Comarco Wireless Technologies. BaseLINE can objectively monitor up to eight different networks simultaneously, evaluating system accessibility, call retention and call quality aspects of system performance. This system simultaneously collects engineering and coverage information useful in the diagnosis of quality problems articulated during the benchmark drive tests. WorkBENCH, a complimentary data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a system supplied with baseLINE, was used to generate the Los Angeles survey report. The Los Angeles network evaluation was the first in a series of syndicated QoS surveys planned for most major wireless markets in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. by year end. This effort is part of a larger strategy to offer independent, third-party competitive quality information to system operators, infrastructure companies and others who have a keen interest in understanding the competitive landscape with regard to Quality of Service issues in the wireless industry.
