OT: Wi Fi Providers

[Tom Bruno]

What do you mean by WiFi?  You mean an actual internet provider that is 
wifi?  Those usually involve external antenna's on the buildings.  If 
you just mean to implement a "simple" wifi network that's independant, a 
simple wireless access point would work fine.

 Depending on your location of course, but i doubt ISP wifi would reach 
you indoors.  As it usually involves line of sight to the towers. 
(Unless your area has setup an "area" hotspot").
