Paul:

...At least Cambridge Positioning Systems didn't try to claim this was new technology, differential time of arrival has been public domain for decades.

But that's the very excuse they are in fact using (since they apparently can't come up with any other) - from the article Rose posted:

EOTD uses up to four different cellular base stations to figure a cell phone's location, measuring the arrival times of the call at various different cellular antennas. But in rural areas, cellular base stations are sometimes miles apart. Instead of four, it's likely there will be just two base stations to help figure out the location, making it less accurate, Wade said.

"This is not developing an IP router or a new kind of modem," he said. "This was brand new, completely unthought-of-before technology that takes a long time."


[My emphasis]

I thought QCOM's SnapTrack GPS approach works on GSM/TDMA as well as CDMA. Is the AWE, Cingular and Voicestream use of EOTD just the result of their resistance to paying QCOM for anything?
