ABSTRACT

Wireless networks are nowadays the most popular means of data communication.
A wireless network is defined as a network protocol that enables online content to be
viewed and accessed via wireless devices such as cell phones, laptops and handheld
devices. Bluetooth is a simple type of wireless networking that allows the formation
of a small network with up to eight devices being connected at once.Wireless
networks may operate on licensed or unlicensed portions of the frequency
spectrum. Some of the types of wireless networks that we come across are
WLANS(Wireless Local Area Networks),WPANS(Wireless Personal Area
Networks),WMANS( Wireless Metropolitan Area Networks),WWANS(Wireless
Wide Area Networks).As far as application point of view the different categories of
wireless networks are CDPD (Cellular Digital Packet Data), HSCSD (High Speed
Circuit Switched Data), PDC-P (Packet Data Cellular),GPRS(General Packet
Radio Service),1xRTT(1x Radio Transmission Technology), Bluetooth,
MMDS(Multichannel Multipoint Distribution Service),LMDS(Local Multipoint
Distribution Service),WiMAX (Worldwide Interoperability for Microwave
Access),802.11(Wi-Fi)The advantages offered by wireless networks lure the users
around the world to switch to wireless networks. But users have to compromise with
the speed limitations offered by wireless networks.
