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.


4/24

Wireless Standards:


5/24

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.

Bluetooth


6/24

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.


7/24

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.


8/24

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.


9/24

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


10/24

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)


11/24

Wi-Fi

"Wi-Fi" stands for

"Wireless Fidelity".The

typical Wi-Fi setup

contains one or moreAccess Points (APs)

and one or more

clients.


12/24

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.


13/24

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

SWOT Analysis

The strengths ofwireless networks are:

Easy to install,

Low price,

High capacity,

No cables to bedestroyed,

No transmission costs(like leased lines).


21/24

Weaknesses include:

Sensitive equipment,

Line of sight needed,

Specialized expertiseneeded,

Capacity lower thanfibre cables.


22/24

Opportunity Side:

They can be used in almost any social or economic

activity that requires large numbers of people to be

involved or connected, especially in rural or remote

areas.


23/24

Regarding Threats,

Transceivers/antennas can be stolen or destroyed,

They can be affected by sandstorms, heat, and powerfailure.

Power scarcity
