This document compares fiber and wireless communication. Fiber communication transmits information via wires or cables using optical fibers, which can carry information faster than metal wires. It has applications in telecommunication, medical systems, networking, and more. Wireless communication transmits information via electromagnetic waves without wires. It allows for mobility and global coverage but can be less secure and have health effects. Both methods have advantages and disadvantages, and different wireless systems currently in use include cellular networks, Wi-Fi, satellites, and personal area networks. Fiber has less loss and interference than wireless but wireless allows communication without physical connections.

3. Fiber Communication:
Method of transmitting information from one place to another by wire or cable
is known as Fiber Communication. Previously maximum fibers are made of
metal but nowadays Optical fiber is more popular for fiber communication.
Cause, it can carry information faster then others.

6. Applications of Optical Fiber:
1) Tele-Communication
2) Medical system
3) Interconnect
4) Networking
5) Gigabit Ethernet
6) Harsh environment
7) Military
8) Aerospace & avionics
9) Data transfer tests
10) Data storage equipments
11) Simulation
12) Semiconductor equipments

7. WIRELESS COMMUNICATION
Wireless operations permit services, such
as long-range communications, that are
impossible or impractical to implement
with the use of wires.
TYPICAL FREQUENCIES
• FM RADIO 88 MHZ
• TV BROADCAST 200 MHZ
• GSM PHONES 900 MHZ
• GPS 1.2 GHZ
• PCS PHONES 1.8 GHZ
• BLUETOOTH 2.4 GHZ
• Wi-Fi 2.4 GHZ

8. How Wireless Communication takes place?

9. Advantages of Wireless Communication
• Freedom from wires.
• No bunch of wires running from here and there.
• “Auto Magical” instantaneous communication without
physical connection setup e.g.- Bluetooth, Wi-Fi.
• Global coverage
• Communication can reach where wiring is infeasible or costly
like rural areas, buildings, battlefield, outer space.
• Easy to connect multiple devices.

10. Disadvantages of Wireless Communication:
The growth of wireless network has enabled us to use personal devices
anywhere and anytime. This has helped mankind to improve in every field of
life but this has led many threats as well.
For example: Hack of Wi-Fi Router is easier then the cable one.
There also some health effect by wireless communication:

11. CURRENT WIRELESS SYSTEMS
• CELLULAR SYSTEM
• WIRELESS LANs
• SATELLITE SYSTEM
• PAGING SYSTEM
• PANs(BLUETOOTH)

12. Main comparison between optical and wireless system
