Introduction
Today, because of scientific
advancement and technicalprowess, the world is getting
smaller but the people are getting
farer from each other. Hence we
need to keep them connected.
And there is no better substitution
for wireless technology.

WIRELESS
Wireless is a method
of communication that
uses low-powered radio
waves to transmit databetween devices.
The term refers to
communication without
cables or cords, chieflyusing radio frequency
and infrared waves.

Bluetooth is a radio standard and communications
protocol primarily designed for low power consumption,with a short range (power class dependent: 1 meter, 10
meters, 100 meters) based around low-cost transceiver
microchips in each device.

DECT(Digital Enhanced Cordless Telecommunications)
It is an ETSI standard
for digital portable
phones, commonlyused for domestic or
corporate purposes.
DECT can also be
used for wireless datatransfers.

DSRC(Dedicated Short Range Communications)
It is a short- to
medium-range
wireless protocol
specifically designed
for automotive use. Itoffers communication
between the vehicle
and roadside
equipment.

HIPERLAN(High Performance Radio LAN)
Planning for the first version of the standard, calledHiperLAN, started 1991, when planning of 802.11
was already going on. The goal of the HiperLAN was
the high data rate, higher than 802.11.

HIPERMAN
(High Performance Radio LAN)
HiperMAN stands for High Performance Radio
Metropolitan Area Network and is a standard created by
the European Telecommunications Standards Institute
(ETSI) Broadband Radio Access Networks (BRAN)
group to provide a wireless network communication in
the 2 - 11 GHz bands across Europe and other countries
which follow the ETSI standard

Wireless Standards:
RFID (It is an automatic identification method,relying on storing and remotely retrieving data using
devices called RFID tags or transponders. An RFID
tag is an object that can be attached to or
incorporated into a product, animal, or person for thepurpose of identification using radio waves. Chip-
based RFID tags contain silicon chips and antennas)

Wi-Fi
"Wi-Fi" stands for
"Wireless Fidelity".The
typical Wi-Fi setup
contains one or moreAccess Points (APs)
and one or more
clients.

WiMax
WiMAX, meaning Worldwide Interoperability for Microwave Access,is a telecommunications technology that provides
wireless transmission of data using a variety of transmission modes,
from point-to-multipoint links to portable and fully mobile internet
access.

xMax
It developed by xG Technology, LLC is an radio frequency
(RF) modulation and encoding technology that uses
individual or "integer" sinusoidal waves to convey
information.W
hile applicable to wired mediums such ascopper and coaxial lines, the technology is first being
introduced as a wireless communications technology
