INTRODUCTION

Direct mobile to mobile communication, also known as device to device, Communication refers to a radio technology that enables devices to communicate directly with each other, that is without routing the data paths through a networkinfrastructure.

*Direct communication B/W nearby mobiles in an exciting and innovative feature of next-GEN cellular N/W.

*It will facilitate the interoperability B/W critical public safety N/W and ubiquitouscommercial N/w eg..LTE.

D2D devices

*what is D2D?

*HOW IT WORKS?

CLASSIFICATION

1.Inband D2D COMMUNICATION

*communication occurs in licensed spetrum.*High control over data spectrum.*High QOS.*Division<under relay and over relay

2.Out band D2D commnication

*Unlicensed spectrum.(Wifi, Zig-Bee, blutooth)*It eliminates interference issues B/w D2D & cellular links.

D2D FUNCTIONAL BLOCK DIAGRAM

POWER CONTROL

*Both static and SINR.*Static TRX is not good for long distance

APPLICATIONS

BENIFITS

*Data rates

*Reliable communication

*Instant communication

*Use of licensed spectrum

*Interference reduction

*Power saving

Conclusion

*Overview on mobile-to-mobile communication to help wireless beneficiaries asses the gain of a D2D system.

*D2D communication aided by a cellular network bring the benefit of the proximity of wireless devices to enhance reusing of resource device between D2D and N/W.

*It expands the business and opportunities that exist.
