Applications
Wireless LANs have a great deal of applications. Modern implementations of WLANs range from small in-home networks to large, campus-sized ones to completely mobile networks on airplanes and trains. Users can access the Internet from WLAN hotspots in restaurants, hotels, and now with portable devices that connect to 3G or 4G networks. Often times these types of public access points require no registration or password to join the network. Others can be accessed once registration has occurred and/or a fee is paid.
