3. Introduction
 LTE Direct is an innovative device-to-device technology
offering privacy sensitive and battery efficient proximity
based discovery of friends, services, offers, and other
relevant value in one’s proximity.
 Creating a digital 6th sense through always-on discovery
services.

4. What is LTE –Direct ?
LTE Direct is creating a Digital 6th Sense through always-on proximal discovery
services
Always-on device-to-device discovery of friends, services, offers in one’s
proximity
{ Proximal discovery services efficiently integrated with existing LTE Advanced
services and networks }
Required to scale up from today’s location-based and proximity beacon
solutions
{ Privacy sensitive and battery efficient discovery of 1000s of devices/services in
the proximity of ~500 meters }
LTE Direct ecosystem implementation underway – defined in 3GPP R12
Operator trials throughout 20141; app developers testing innovative use cases
today with LTE Direct Trial SDK2

5. Proximity and Location
 Proximity and Location are of course related, as in:
- If I know the location of two things or places (say A, B), then I can
determine how proximate they are (or how close they are).
- Also, if I'm thing or place (A), and I can detect that (B) is "near" or
proximate to me, then I may be also able to derive some location
information.
A best example is : if (B) is the statue of liberty, and I just figured out it was
"near" by taking a photo of the statue and goggles to identify it, then I'm
pretty sure that I'm near New York..

6. What can be done using Proximity Services
 The proximity platforms do two key things:
- Tell you about "devices" nearby (typically devices discoverable and detectable
because they have some short range wireless on board)

- Let you decide whether any of those devices are "of interest" to you (in other
words, you can store meta information about them for your own purposes).
Thus sharing :
- Person to person stuff - discover and share information about things / people
nearby -
- Person to business stuff - enable a business to detect you for reasons of
triggering coupons, loyalty, offers, deals.
 Privacy Sensitive, Efficient, Scalable,Always ON proximal discovery.

34. Conclusion
 LTE Direct is a new and innovative device-to-device technology being
standardized in 3GPP-R12. It enables "always-on" discovery of thousands of
devices and their services in a proximity of 500m, in a privacy sensitive and
battery efficient way.
 LTE Direct uses licensed spectrum, allowing mobile operators to employ it to
offer a range of differentiated applications and services to users. Its potential
for application development is huge, with possibilities extending to social
discovery, advertising, gaming, education, emergency services and much
more.
 LTE Direct relies on the LTE physical layer to provide a scalable and universal
framework for discovery and connection
 A Privacy Sensitive, Efficient, Scalable, Always ON proximal discovery.
