I'd be interested in hearing comments regarding the impact on qcom if Vodaphone and AirTouch end up together. Would this provide even more pressure on E regarding cdma and QCOM in Europe? Looks like LWIN is acquiring Chase. Are there infrastructure opptys here for Q? if so any insights as to the potential? Thanks Web

Position location in terrestrial cellular Pierre, Qualcomm has done it again. Klein Gilhousen and crew have come up with a way to keep an eye on you using terrestrial CDMA systems. They have a rotating aerial [electronically, not physically] which measures the direction of the handset, then the time for the handset to respond defines the distance. Hey presto, a nano second later they know exactly where you are! Which is apparently a legal requirement coming in for USA people using cellphones. Even my funny metal hat, which will work to stop Globalstar knowing where you are won't stop this one from pinning you down. This will be very good if you are in trouble as you could dial 111 or 999 or whatever emergency number you use and they will know where you are! Hey Presto, instant assistance even if you don't know where you are. Not so good if you are on the run from the CIA because you have offended Bill Clinton and he wants you nailed. Try to make a call and they'll have you!

Bozeman, MT OTHER DETAILS: Legal Rep: Miller; Russell B. Application Date: Jun-06-1996 Application Number: 659408 Primary Examiner: Tarcza; Thomas H. ABSTRACT: A method for determining the position of a mobile station within a cellular telephone system having a plurality of base stations. A signal is transmitted from a rotating antenna. The rotating antenna has a beam which rotates around a cell in the cellular telephone system. The beam has a rotational timing that is known by the mobile station. The signal is received at the mobile station. Based on a reception time when the signal is received by the mobile station, an angular displacement value corresponding to the position of the mobile station is determined. A first round trip signal propagation time between a stationary antenna and the mobile station is measured using a voice information signal. The position of the mobile station is determined in accordance with the angular displacement value and the first round trip signal propagation time. A method for determining the position of a mobile station within a cellular telephone system having a plurality of base stations. A voice information signal is transmitted from the mobile station. The voice information signal is received with a first antenna having a rotating beam for receiving the signal. Based on a reception time when the voice information signal is received by the first antenna, an angular displacement value corresponding to the position of the mobile station is determined. A first round trip signal propagation time between a second antenna and the mobile station is measured. The position of the mobile station is determined in accordance with the angular displacement value and the first round trip signal propagation time. ---------------------------------------------------------------- Meanwhile, as you said, Vodafone seems to be the CDMA camel's nose under fortress Europe's tent.
