Wireless communication is the transfer of information between two or more points not connected by an electrical conductor, most commonly using radio technologies. The document outlines the history of early wireless experiments in the 1870s and types of modern wireless communication including satellite, radio, internet, infrared, Bluetooth, mobile systems, and Wi-Fi. Advantages include flexibility, ease of use, planning and durability while disadvantages involve compatibility, Ethernet and weak signals. In conclusion, wireless connectivity has made communication faster, easier and more convenient by eliminating wires over long distances.

WIRELESS COMMUNICATION

2. INTRODUCTION
• What is Wireless communication?
Wireless communication is the transfer of information between
two or more points that are not connected by an electrical
conductor.
The most common wireless technologies use radio.
 Early Wireless Work
David E. Hughes transmitted radio signals over a few hundred
yards by means of a clockwork keyed transmitter in 1878
The world's first wireless telephone conversation occurred in
1880, by Alexander Graham Bell called it photophone.

3. TYPES OF WIRELESS COMMUNICATION
• Satellite Communication
• Radio Communication
• Internet Communication
• Infrared Communication
• Bluetooth Communication
• Mobile Communication Systems
• Wi-Fi Communication

4. RESULTS
Advantages:
• Flexibility
• Ease of use
• Planning
• Durability
• Price
Disadvantages:
• Compatibility
• Ethernet
• Weak signals

5. CONCLUSION
We can easily connect, communicate and share faster.
Wireless made us wire-free and less the problem of
wiring long distance and usage of so much of wire. It
has made us to communicate very long distance easily
and cheaply. Wireless has come to so many devices and
products that everyone is getting connected to each of
them and making it more easy to use, where as it is
becoming faster and faster everyday to
transfer/communicate data.
