SAFCO Finds Differences Between Manhattan's
Wireless Networks
More Than 14,000 Calls Placed Over Seven Wireless Networks in Manhattan
CHICAGO--(BUSINESS WIRE)--Nov. 4, 1999--SAFCO Technologies, Inc., a Salient 3 Communications company
(NASDAQ: STCIA - news), today announced that it has completed a highly-detailed wireless network benchmarking study
comparing the call quality of the digital and analog cellular and PCS networks in metropolitan Manhattan.
SAFCO's JTFM benchmarking studies compare competing wireless operators using four measures of network performance:
voice quality (MOS), dropped calls, blocked calls and no service. In addition to these parameters, SAFCO engineers analyze
key engineering metrics for each cellular technology. In this study, all of the major wireless technologies, including CDMA,
TDMA, GSM, iDEN(R) and AMPS, were surveyed. Overall quality rankings are then given to wireless operators in that
market.
In Manhattan, the best mean voice quality score, 3.38 (on a scale of one to five with five being the best), was achieved by one
of the CDMA networks. In addition, one of the CDMA networks recorded the lowest number of blocked calls, while one of
the analog networks recorded the lowest number of dropped calls. Although, the surveyed wireless operators provided
adequate coverage in Manhattan, one digital network had capacity and noise issues. The voice quality for the iDEN(R)-based
network was second only to CDMA.
''We are proud to deliver this report to the industry,'' said Marty Singer, SAFCO president and CEO. ''The report gives an
independent assessment of the competing networks and answers some important questions regarding digital and analog service
in Manhattan. Central Park was the only area not criss-crossed by our drive-test vehicles.''
SAFCO's JTFM network benchmarking reports provide an objective, unbiased view of the quality of service in each wireless
market evaluated and are available for purchase on a per report basis or as part of a subscription service. Detailed statistics
and geographic presentations are available for the New York City study as well as for others in the SAFCO benchmarking
archives.
Network benchmarking not only provides valuable information to operators, vendors, financial institutions, tower management
firms, industry trade groups and consumer groups, but also provides market intelligence necessary to remain competitive and
informed in the rapidly changing world of telecommunications.
In 1999, SAFCO has conducted surveys in more than 20 major wireless markets including Atlanta, Charlotte, Chicago,
Jacksonville, Miami, Orlando, Tampa, Washington, D.C., London, Hong Kong and Tel Aviv, Israel. SAFCO currently
maintains a network performance database of approximately 220 networks. SAFCO has completed and plans to release
studies on Philadelphia and Boston later this month.
