How Wireless (WiFi) Networks Work
1* A key component of an 802.11 network (also called a
WiFi network) is an access point or router also called an
AP). The access point consists of a radio transmitter and
receiver as well as an interface to a wired network such
as an Ethernet network, or directly to the Internet. The
access point serves as a base station and a bridge
between the wireless network and a larger Ethernet
network or the Internet.

How WiMax Works
1* WiMax (Worldwide Interoperability for Microwave
Access) is similar to WiFi, but broadcasts over an entire
metropolitan area, rather than just a single location, using
the 802.16 standard. A wireless Internet service provider
(WISP) provides WiMax Internet service. The WISP, like
other ISPs, needs to connect to the Internet via a highspeed backbone, so that it can provide Internet service to
its subscribers.

How Home Networks Work
• 1* The main reason people set up home
networks is to share high-speed Internet
access, such as via a cable modem or DSL
modem, among several computers. To give the
home network access to the Internet, an
Ethernet cable runs from the cable modem or
DSL modem to the networking device, called a
router.
