Google Deducing Wireless Location Data

bizwriter writes "When it comes to knowing where wireless users are, the carriers have had a lock on the data. But a patent application shows that Google is trying to deduce the information based on packet headers and estimated transmission rates. This would let it walk right around carriers and become another source of location data to advertisers."

What's stopping carriers from deliberately slowing transmission rates for random customers during random intervals? Just enough such that Google's data is inaccurate.
