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.
Wireless adapter
Most computers feature a wireless module and Wi-Fi button that
turns the network connection on or off. You may also turn your
wireless network on or off, or control what is shared over the
network with the network management options.
Warning
Using wireless devices while flying in aircraft may be prohibited.
Switch off all devices before boarding an aircraft; they may be
dangerous to the operation of the aircraft, disrupt
communications, and even be illegal. After take off, ask the cabin
crew if you may enable Wi-Fi.
