Wireless communication is nothing but the transferring of data
over a particular distance without using the long, irritating, tubular
things called wires.
Certain ISPs offer access to the Internet without your first having
to plug in a wire to a jack. Such services may use different
types of wireless technologies:
❍ GSM: Global System for Mobile communication, which compresses
information and then transfers it over a single channel.
❍ CDMA: Code Division Multiple Access transfers data by distributing
it among different available radio channels.
❍ Wi-Fi: A common wireless network, broadcasting radio waves
that can be caught by Wi-Fi receivers in individual computers.
The Wi-Fi service operates by setting up Wireless
“access points” that connect a group of wireless devices.
❍ WAP: (Wireless Access Protocol) is a standard that allows cellular /
wireless devices to access the Internet. The main application
of this standard is to allow cellular phones or PDAs (Personal
Digital Assistants) or Notebook computers to get access to
the Internet, again, without having to plug a wire in.
