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.

Applications of Optical Fiber:

1) Tele-Communication2) Medical system3) Interconnect4) Networking5) Gigabit Ethernet6) Harsh environment7) Military8) Aerospace & avionics9) Data transfer tests10) Data storage equipments11) Simulation12) Semiconductor equipments

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

How Wireless Communication takes place?

Transmitting signal Received signal

Satellite

Transmitting Antenna

Receiving Antenna

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.

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:

CURRENT WIRELESS SYSTEMS

• CELLULAR SYSTEM

• WIRELESS LANs

• SATELLITE SYSTEM

• PAGING SYSTEM

• PANs(BLUETOOTH)

Main comparison between optical and wireless system

PARAMETERS OPTICAL FIBER WIRELESS SYSTEM

1) Basically define It is wired system and used light.

It is wireless system and used electromagnetic waves.

2) Main Principle Total internal reflection. Modulation and demodulation techniques are used.

3) Component For transmission- LED and LASER,For receiver-PHOTODIODE

ANTENNA, MODULATOR and DEMODULATOR

4) Frequency Approx 180 THz to 330 THz Approx 300 GHz to 3000GHz

5) Loss 0.002db/km (approximate), scattering and absorption problems.

Low bandwidth, Weather problems, Interference problems.

6) Applications Telecommunication, Imaging optics , Endoscope

Mobile phones, broadcasting, Wireless fidelity (Wi-Fi), Satellite communication.

So, Which is better Fiber or Wireless?
