To All: Does this mean $$ to QCOM for use of CDMA? Roger ---------------------------------------------------------------- July 15, 1998 Telcel of Venezuela Selects Lucent Technologies for cdmaOne Overlay of Its Wireless Network CARACAS, Venezuela--(BUSINESS WIRE)--July 15, 1998--Lucent Technologies today announced it has received a contract -- valued at up to $100 million - to upgrade the cellular network of Telcel, Venezuela's leading wireless telecommunications service provider. Telcel will upgrade its system from analog to digital, utilizing the cdmaOne(R) digital wireless standard, a step that will expand the capacity and customer features of its cellular network. The initial phase of the modernization project is slated for Caracas, the capital of Venezuela, where Lucent will install a mobile switching center (MSC), using its flagship 5ESS(R) Switch and Autoplex(R) System 1000 Series II cell cites, and will provide technical expertise and support services. "We believe Lucent's advanced technology platform provides the innovation we require to move into the next generation of services that our customers demand," said Enrique Garcia V., president, Telcel's Operations Group. "As competition intensifies with the coming deregulation of Venezuela's telecommunications marketplace, innovation and reliability will determine how successful we are in winning subscribers." Mario Lizaso, president, Telcel's Corporate Group, stated, "Lucent Technologies was one of two vendors to conduct CDMA trials with Telcel in 1996. The trials proved CDMA's technological advances and potential for growth, combined with superb voice quality." The new Lucent equipment incorporating the cdmaOne standard is based on code division multiple access (CDMA), the newest commercially deployed digital wireless technology based on an industry standard called IS-95. This technology provides wireless carriers with greater call capacity than analog and other digital systems and offers customers enhanced call quality that is comparable to landline service. CDMA reduces the static and cross-talk sometimes heard on analog systems and provides a "soft hand-off" capability that makes call hand-offs between cell sites and mobile switching centers (MSCs) virtually unnoticeable to customers. "We are extremely pleased to have been selected as Telcel's technology upplier in this important project," said Carlos Linares, vice president for South America at Lucent Technologies. "We believe our system architecture is a key selling point since the network we install today has all of the necessary features to allow for smooth transitions to future innovations." Telcel is a joint venture between BellSouth and Venezuelan-based Comtel. Telcel holds 60 percent share of the cellular market in Venezuela, with more than 350,000 subscribers in Caracas alone and over a million throughout the nation. Operating on the A-Band license, the company began commercial service in 1991. Further information about Telcel is available on the worldwide web at telcel.net.ve Lucent Technologies is a leading provider of wireless infrastructure equipment utilizing all of the major global wireless standards - AMPS, TDMA, CDMA and GSM. An industry leader in CDMA technology, Lucent has more than 100 cdmaOne networks either in commercial operation or under construction for 25 network operators worldwide.

Those are good points but I believe that you are mistaken about the transmission. From what I understand in TDMA applications you pulse the power to the PA. This turns the PA on and off and thus saves power. What this means to me is that until you come to your timeslot your PA is off and that is your most power hungry device in your phone by far. I guess what I mean is that I was misunderstood. I was not referring to voice activity (what determines the rate in CDMA) but instead to the fact that you do not have your time slot there all of the time and must pulse your transmission to coincide with your timeslot.
