Device‑to‑device communication, slated for LTE‑A Release 12, promises higher spectrum efficiency, throughput, and energy savings, lower latency, and new peer‑to‑peer services, but introduces significant challenges to the base‑station‑centric cellular architecture. The article aims to explain the architectural and technical challenges of D2D communication in the 3GPP standard and to highlight real‑life applications and use cases. The authors analyze these architectural and technical challenges and discuss real‑life applications and use cases for D2D communication. D2D offers diverse business opportunities, supporting its candidacy as a key component of next‑generation wireless systems.
Direct mobile-to-mobile communication, also known as device-to-device (D2D), is expected to be a part of LTE-A in 3GPP Release 12. Direct communication will improve spectrum efficiency, overall system throughput, and energy efficiency, and decrease the delay between devices. It will enable new peer-to-peer and location-based applications and services. Introducing D2D poses many challenges and risks to the longstanding cellular architecture, which is centered on the base station. Therefore, in this article we explain the architectural and technical challenges for D2D communication in the 3GPP standard, and at the end of the article we also highlight the real-life applications and use cases for D2D communication. It is clear that D2D can offer a palette of interesting colors that can paint new business opportunities for mobile stakeholders, promoting its candidacy for next generation wireless communication system.
