Are you sure about signal all the way to Cornwall ? In the past, signal
stopped somwehere between Coteau du Lac and the Ontario border. The Fido web
site still shows this to be the case.

I suspect your phone may have roamed into another network, perhasop AT&T in
canada or some network in the USA (which is just across the st-lawrence) once
you get into ontario).

If I were Fido, I would be looking at the portions of the 401 with the most
traffic.
That would mean progressively going east from Toronto until Kingston. Not sure
if Fido would roll out in Kingston, but since it is a university town, perhaps
there would be significant customer potential there.

east of kingston, it becomes harder to justiofy since traffic is lighter. But
Kingston to Prescott carries both Ottawa and Montreal bound traffic. Then, you
have the stubs to ottawa and to Coteau to cover which have the lightest traffic.

Another decision Microcell needs to make is whether to extend coverage to the
CN tracks for Via trains where those tracks are not near enough the highway.
In my opinion, someone traveling by train is far more likely to use his mobile
and laptop with gprs than someone driving. So the right market research might
reveal if Via would generate more revenus to Microcell than the 401.

It would be interesting to see how many extra towers Bell and AT&T needed to
cover the CN tracks and if they have statistics on the number of calls which
travel though those additional cells.

(if you have a call that travels from a cell near highway to one near the
tracks, it means a pax on a train having a long conversation).
