What is a wireless network made up of?

An ad-hoc, or peer-to-peer wireless network consists of a number of computers each equipped with a wireless networking interface card. Each computer can communicate directly with all of the other wireless enabled computers. They can share files and printers this way, but may not be able to access wired LAN resources, unless one of the computers acts as a bridge to the wired LAN using special software. (This is called "bridging")

Ad-Hoc or Peer-to Peer-Networking.

Each computer with a wireless interface can communicate directly with all of the others.

A wireless network can also use an access point, or base station. In this type of network the access point acts like a hub, providing connectivity for the wireless computers. It can connect (or "bridge") the wireless LAN to a wired LAN, allowing wireless computer access to LAN resources, such as file servers or existing Internet Connectivity.

There are two types of access points:

Dedicated hardware access points (HAP) such as Lucent's WaveLAN, Apple's Airport Base Station or WebGear's AviatorPRO.

Software access points, such as the SoftRouter Plus or Internet Gateway, which run on a computer equipped with a wireless network interface card as used in an ad-hoc or peer-to-peer wireless network.

With appropriate networking software support, users on the wireless LAN can share files and printers located on the wired LAN and vice versa. CPI's solutions support file sharing using TCP/IP.
