Wi-Fi Hotspot – definition from Answers.com
The geographic boundary covered by a Wi-Fi (802.11) wireless access point. Typically set up for Internet access, anyone entering the hotspot with a Wi-Fi-based laptop, PDA or smartphone can connect to the Internet, providing the access point is configured to advertise its presence (beaconing) and authorization is not necessary. If authorization is required, the user must know the password.
It May Be Hidden
If an access point is invisible by virtue of the fact that it is not advertising its presence (not beaconing), the user must know the name of the network (the SSID) and most likely the password as well (see beaconing and SSID). Following are some of the Web sites that report hotspot locations.
