The base station is typically  connected to the  wired internet and thus serves to connect wireless users  to the wired  networks. In wide area wireless  access networks the base stations is  managed by a telecommunications  provider and serves users within  a radius of  tens of kilometres.

This  networks allows  the residents  to having broadband internet access, if  one member roaming form  the kitchen to the backyard or to the bedroom.
