Wireless networks: A wireless network is any type
of computer network that uses wireless data
connection for connecting network
 Digital device: A device that represents
information using the convention building on the
binary digits 0 or 1.

3.
THE WIRELESS REVOLUTION
 Mobile phones have become mobile platforms for delivering
digital data, used for recording and downloading photos,
video and music, Internet access, and transmitting payments.
An array of technologies provides high-speed wireless access
to the Internet for PCs and other wireless handheld devices
and cell phones.
 Businesses increasingly use wireless to cut costs, increase
flexibility, and create new products and services.

4.
WIRELESS TRANSMISSION MEDIA AND
DEVICES
 Microwave systems transmit high-frequency radio
signals through the atmosphere.
 Communication satellites are used for
geographically dispersed organizations

5.
DEVICES FOR WIRELESS TRANSMISSION
Cellular telephones
Personal Digital Assistants (PDAs)
Smart phones

6.
ADVANTAGES
 It is convenient to use
 This wireless network can serve increasednumber
of clients with existing equipment
 Cost is less than wired network

7.
CELLULAR NETWORK STANDARDS AND
GENERATIONS
Standards:
 Global System for Mobile Communication (GSM)
Code Division Multiple Access (CDMA)

8.
STANDARDS
GSM: Developed to provide common 2nd-
generation technology for Europe.200 million
customers worldwide, almost 5 million in the North
America
CDMA: It is a channel access method used by
various radio communication technologies

9.
CELLULAR GENERATIONS
1G: Analog cellular networks for voice
communication
2G: Digital wireless networks, primarily for voice
communication, limited data transmission
capability

10.
CELLULARGENERATIONS (CONTINUED)
2.5G: This is between 2nd and 3rd generations and
it is associated with General packet radio
services(GPRS)
3G: High-speed; mobile; supports video; always-
on transmission for e-mail, Web browsing, instant
messaging

11.
MOBILE WIRELESS STANDARDS FOR
WEB ACCESS
Wireless Application Protocol (WAP): Uses Wireless
Markup Language (WML) and micro browsers
I-mode: Uses compact HTML and allows for
continuous connection

12.
WIRELESS APPLICATION PROTOCOL
(WAP) VERSUS I-MODE

13.
THE INSTITUTE OF ELECTRICAL AND ELECTRONICS
ENGINEERS (IEEE) ESTABLISHED GLOBAL WIRELESS
NETWORK STANDARDS
Global Wireless Network Standards: IEEE 802.15
(Bluetooth) for the Personal Area Network (PAN).
IEEE 802.11 (Wi-Fi) for the Local Area Network
(LAN)

14.
A BLUETOOTH NETWORK (PAN)

15.
BLUETOOTH:
It is a wireless technology standard for exchanging
data.
It Can link up to 8 devices in 10-m area
Low power is required for data transmision

16.
WI-FI
Infrastructure mode: Devices use access point to
communicate with wired network
Ad-hoc mode (peer-to-peer): Wireless devices
communicate directly with each other

17.
RADIO FREQUENCY IDENTIFICATION
(RFID)
Radio Frequency Identification (RFID) systems:
Provide a powerful technology for tracking the
movement of goods throughout the supply chain

18.
HOW RFID WORKS

19.
CONCLUSION
Wireless networks having low cost compared to the wired
network.
High flexibility.
