Slide 2: 

Introduction Wireless Communication History Photophone Radio Electro Magnetic Spectrum Types of wireless communication Examples of wireless communication Applications Advantages Disadvantages Conclusion

WIRELESS : 

WIRELESS Any type of electrical or electronic operation accomplished without use of wires Wireless connections use air to connect sending and receiving devices Channel is a division in transmission medium

COMMUNICATION : 

COMMUNICATION It is transmission of signals i.e. sending of electromagnetic waves by electronic transmitters. sending Sending device message Connection device Communication channels Connection device message Receiving device Sending device message Connection device Communication channels Connection device message Receiving device Sending device message Connection device Communication channels Connection device message Receiving device

WIRELESS COMMUNICATION : 

WIRELESS COMMUNICATION Communication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves Wireless communication may be via: Radio frequency communication Microwave communication Infrared short range communication Wireless modem:– It is a modulator-demodulator which enables communication at fastest speeds, typically in bits per second

APPLICATIONS : 

APPLICATIONS SECURITY SYSTEMS TELEVISION REMOTE CONTROLS CELLULAR TELEPHONES WI-FI WIRELESS ENERGY TRANSFER COMPUTER INTERFACE DEVICES

CELLULAR PHONES : 

CELLULAR PHONES Use radiowaves to enable the operator to make phone calls from many locations worldwide.

Wi – Fi WIRELESS FIEDELITY : 

Wi – Fi WIRELESS FIEDELITY Analogous to traditional ethernet network Enables faster connections Better range Better security More spatial capacity i.e. bits per second per square metre
