• LTE-Assisted WiFi Direct system
◦ Significant operator & user benefits from
„next generation“ proximity services
◦ Battery/channel efficient, secure
discovery of nearby devices and services
• Automated D2D (device-to-device)
connectivity and service continuity
• Licensed bands offloading and
enriching applications and services
in current mobile ecosystem
• 3GPP-compliant technology ratified
in LTE Rel.12 and 13

• Dynamic LSA framework
◦ Enables authorized spectrum sharing to access the
common frequency band collectively
◦ Efficient way for the cellular network operator and
the incumbent (spectrum owner) to share spectrum

3GPP LTE-A System
• Enabling secure direct communication not only in the cases of permanent
(reliable) cellular connectivity, but also in situations when it becomes
temporarily unavailable
• D2D users may "lose" their controlling cellular link, but can still continue
exchanging protected data as well as manage secure groups (coalitions)
