Wireless networks
A wireless LAN or WLAN is a wireless local area network, which
may link two or more computers without using wires. Setting up a
wireless network is easy and allows you to share files, peripheral
devices and an internet connection.
What are benefits of a wireless network?
Mobility
Wireless LAN systems allow you and other users of your home
network to share access to files and devices connected to the
network, for example a printer or scanner.
Also you can share an internet connection with other computers
in your home.
Installation speed and simplicity
Installing a wireless LAN system can be fast and easy and
eliminates the need to pull cables through walls and ceilings.
Components of a wireless LAN
To set up your Wireless network at home you need to have the
following:
Access point (router)
Access points (routers) are two-way transceivers that broadcast
data into the surrounding environment. Access points act as a
mediator between wired and wireless network. Most routers have
a built-in DSL modem that will allow you access to a high speed
DSL internet connection. The ISP (Internet Service Provider) you
have chosen normally supplies a modem/router with the
subscription to their services. Read carefully the documentation
supplied with your Access point/router for detailed setup
instructions.
Network cable (RJ45)
A network cable (also called RJ45 cable) is used to connect the
host computer to the access point (see illustration below); this
type of cable may also be used to connect peripheral devices to
the access point.
