Wireless Technology
Beyond the wire culture
2
Overview

Wireless communication involves the
transmission of information over a
distance without help of wires, cables
or any other forms of electrical conductors.
The transmitted distance can be anywhere
between a few meters (for example, a
televisions remote control) and
thousands of kilometres (for example, radio
communication).
3
Different Modes

• Wireless Communication can be via
• microwave communication
• radio frequency communication
• Infrared communication
• Also some aplications may involve various
• point-to-point communication, point-to-multipoint
  
• communication, broadcasting, cellular networks
• and many more other wireless connections.

4
Microwave Communication

• Microwave communication is commonly occur to
  transmit data over long distances.
• It relies on high frequency microwave radiation
  that travels at the speed of light.

5
Advantages

• Can cover large distances over rough terrain
  where you could'nt bury cables.
• High Speed
• Multi-channel transmissions
• Wide bandwidth

6
Radio Frequency Communication

• A radio frequency (RF) signal refers to a
  wireless electromagnetic signal used as a form of
  communication.

7
Advantages

• It offers mobility
• Cheaper
• Offers freedom from land acquisition rights
• Ease of communication over difficult terrain

8
Infrared Communication

• Infrared Wireless Communication communicates
  information in a device or systems through IR
  radiation.
• IR is electromagnetic energy at a wavelength that
  is longer than that of red light.

9
Advantages

• Doesn't interfere with other signals
• Cannot pass through walls
• Low power required- ideal for laptops,
  telephones, personal digital assistants
• Portable
