Hotspots are areas where WiFi radio signals can be picked up by your
computer. At home, a wireless router (such as the one shown at right)
does the job to make your entire home a hotspot.
Away from home hotspots can be found in most airports, libraries, hotels
and a growing number of cafes, as well as other places. There are
people known as "Warchalkers" who, once they have found a WiFi
connection at a particular spot, will write the necessary connection
details on a nearby wall in, of course, chalk. This practice can be
illegal in certain jurisdictions, although the laws are generally
unclear at this time.
As more hotspots appear the WiFi coverage will expand and WiFi will
become a more widely used and popular alternative. Eventually WiFi
coverage will be no different from the Cell Phone network we take for
granted.
