What is Wireless Networking?
With the help of wireless
technology we can transfer data
from one device to another
without using wire or cables.
Using this technology we can
establish network which is more
flexible, intangible and ease to
access.

Wireless Networking Data
Transmission
Generally implemented and administered
using:
Radio Transmission (Mostly)
Light Transmission
Infrared and Millimeter waves
Microwave Transmission

Components Requirements
The important components required for
setting up a wireless network are:
Medium
Access point and Extension point
Wireless bridges and Power line
bridges
Antennas
Wireless adapters
Wireless Station and Server
Software

Types of Wireless Networks
Based on the size Wireless Networks are
divided into four categories .
 Wireless LAN
 Wireless MAN
 Wireless WAN
 Wireless PAN

Wireless LAN
This is a network where two or more
computers are connected that covers only a
limited area.
The NIC ( Network Interface Card)is used in
this connection where has a small range to
cover.
 We often called this peer to peer Network.

Wireless MAN
Collected unit of many WLAN located at
various.
 It uses WIMAX(World wide Interoperability
for Microwave Access) which is controlled by
WiMAX Forum.
 Maximum speed 1Bits/sec.

Wireless WAN
WWAN is a very large network which is spread
over a very large area. It connects many cites
together.
The technology in WWAN are subdivided in
many generations: 2G, 3G, 4G.
 This technology used in most of the Analog
devices.

Wireless PAN
The Wireless Networks that are used in
smaller distance are know as WPAN.
 The communication between a mobile phone
and its Bluetooth headset.
Two kinds of Wireless technologies are used
for WPAN.
 Bluetooth and Infrared Data Association.

Security Options in Wireless
Network
Data can be easily hacked in Wireless network without
using proper security.
Three commonly used security system:
1. Wired Equivalent Privacy(WEP)
2. Wi—Fi Protected Access(WPA)
3. Wi—Fi Protected Access(WPA2)

WEP:
1. Security standard released in 1997.
2. The Encryption Algorithm used in WEP was easily
Breakable by Hackers.
WPA
1. Released in 2003, Invented by Wi—Fi Alliance
2. Required Firmware up gradation instead of changing any
hardware component.
WPA2
1. Released in 2004
2. Advanced security features are available
3. Advanced Encryption Standard

Why we use wireless
Networking?
It is helpful for portable devices such as
Laptops, mobiles, tablets etc.
Establish a network connection is easy.
Introducing a new device in the
Network is easy.
Security system is more featured in
wireless Networks.

Advantages of wireless
Networking
Access and accessibility improved.
Backwards compatible as standards
improve.
Cost Savings.
Speed of installation.

Disadvantages of wireless
Networking
Conflict of standards.
Security.
Transmission speeds can fluctuate.
Slower then wired.
