4.5.1 Overview
4.5.1.1 What is wireless network
There are two types of wireless network setup: Client Mode
(infrastructure) and Ad Hoc Mode (peer-to-peer). Client mode
is an 802.11 networking framework, in which devices
communicate with each other by first going through a wireless
router or access point. Wireless devices can communicate with
each other or can communicate with a wired network.
Generally, a majority of small businesses and home users
operate in Client Mode because they require access to the
wired LAN (usually from broadband or cable Internet providers)
in order to use services such as file servers or printers.

Ad Hoc (sometimes referred as peer-to-peer) is a type of
wireless network allowing a wireless adapter or other
Ethernet-ready device to connect directly to another wireless
adapter or Ethernet-ready device.
