Home Work: How WiFi and WiMax Work

--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 high-speed backbone, so that it can provide Internet service to its subscribers.
