What's the difference between a WLAN and a WWAN?
WLANs are generally privately owned, wireless systems that are deployed in a
corporation, warehouse, hospital, or educational campus setting. Data rates are high
and there are no per-packet charges for data transmission.
WWANs are generally publicly shared data networks designed to provide coverage in
metropolitan areas and along traffic corridors. WWANs are owned by a service
provider or carrier. Data rates are low and charges are based on usage. Specialized
applications are characteristically designed around short, burst messaging.
What is Ad Hoc mode?
A wireless network consists of a number of stations without access points. Without
using an access point or any connection to a wired network.
