This is actually a technical question. There are talks about a proposal to make the entire Philippines a wifi zone. From what I understand, a wifi zone is like a cellphone area where a cell site is needed to be installed. For a wifi to work, there should be a transmitter or satellite dish for the signal. Pardon me if I sound ignorant on the technical terms. I just want to know how a city can be a wifi zone entirely... and also an entire country.
