Wifi networks are made up of powerful wireless routers (or interconnected sets of wireless routers) that use radio signals to carry information between communicating devices. The central wireless router, sometimes called an "Access Point," or AP, provides the radio signal that allows wireless computers, printers, PDAs and cell phones within the service area of the Access Point's antenna to connect to the network and the Internet. If you're setting up an entry-level Wifi network, all you need is a broadband ISP connection, a cable or DSL modem, a wireless router, and a set of wireless receiving devices for the wireless clients you expect to access the LAN.
Walls and other equipment indoors interfere with the radio signal and reduce the radius of effective wireless coverage. You can expect to get an effective 100 foot radius of indoor service from a router or AP, and 300 feet outdoor (where there are fewer obstacles to interfere with the radio waves). To expand the service area of your wireless network, you can add additional APs and interconnect them using standard Ethernet cables or special wireless connections.
