I would love to hear more about this technology that you are talking about.
When I worked at AT&T Wireless and Ericsson, we tested many positioning
technologies. If you are talking about time alignment factor both on GSM and
TDMA, and even with neighboring cell information, and even combine it with
smart array antenna technology, I doubt if you can get close to 15 meter
accuracy. Given the moving vehicle speed or even walking speed, I`m curious
to learn about how the technology can get to 1 m precision. So please share
with me about the technology you are talking about.
Thanks,
