Of course they are legal, but the prices are just nuts..
Remember what I said about them being responsible for their own network performance. Since we (end users) are paying for the cell service, we should be able to get a dial tone and clear reception, and transmission, period.
Don't buy the service twice.. As you are already paying for it without buying all that expensive junk.
The record for wifi range is over 200 miles.
Link Cell phones are somewhat different, but line of sight limits the range, because of the curvature of the earth.
If you are standing on the surface of a flat earth, your radio range is not very far at all. Maybe 5 miles.
Most cell phones have some kind of external antenna hookup (usually beneath some small rubber plug) Depending on the phone, the addition of a real gain antenna can multiply range many times.. That is the best way to get cell phone coverage far away from the roads.. You may have to climb a bit to get up high enough but ones chances are fairly decent in most areas.. Some mountain you can see is likely to have a cell you can hit. You can in a pinch make a corner reflector.
It could be worse.. Imagine you were in North Korea.. where making a long distance cell phone call is a capital offense. punishable
by execution.
