A network that transmits wireless from computer to computer without the use of a base station (access point). Two or more wireless stations communicate directly to each other.
  • Page 32 ROAMING In an infrastructure network, wireless stations are able to switch from one BSS to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization among other factors.
