Not with anything vaguely resembling the accuracy you seek. Network
provider, in the form of cell tower triangulation, is good for a 1km
or so. The only technology that presently exists that can give you 50m
accuracy is GPS. Galileo, perhaps, in a few years, maybe, if it
happens, but that's not today. WiFi hotspot proximity can also do
pretty good, but that's not likely to be useful in your scenario.
