Is that a technical issue requiring your services, or is it just a question of the officer looking at a map and saying that this circumference is too large? Is it a technical issue that involves the coverage that telecommunications towers have in a particular area? You wouldn't want to chance the signal breaking. We can sometimes live with losing contact on our cellphones for 30 seconds when we're driving through the countryside, but I imagine it would be important to not have that kind of break in transmission.
