Cell-ID location technique, limits and benefits: an experimental study (WMCSA 2004)

Driving in USA & Italy collecting GPS and CELL-ID info (Italy - GSM, USA - something else)

Showed average of 800m accuracy in USA and 500m in Italy

Most of the time, not the closest base-station is chosen as the "strongest" one.

Short survey of localization methods

Propose to use voice street recognition with cellid info to limit the grammar size (streets that can be spelled into the system)
