Implementing secure LTE-assisted D2D framework for unreliable cellular connectivity

To comprehensively demonstrate our recently developed information security framework for assisted D2D connectivity, we committed to construct a prototype application on top of the contemporary Android platform. The application has the functionality of a secure data messenger, which remains operational when the cellular link becomes unavailable (unreliable) and allows users to directly exchange confidential information, as well as manage private user groups (coalitions).

LTE-Assisted WiFi-Direct: A unique trial of network-assisted D2D technology

As the dust around 5G communications technology settles, it becomes clear that it will be a synergistic integration of diverse techniques and solutions, rather than one killer technology, with the goal to dramatically improve the performance of next-generation wireless networks. In this space, network-assisted device-to-device (D2D) infrastructure is seriously considered now as part of future 5G ecosystem, due to its capability to offload expensive cellular bands, as well as owing to next-generation applications and services that it enables, thus leading to new market opportunities. In particular, LTE-assisted WiFi-Direct is a promising technology that creates unprecedented benefits, for both operator and end user, at the stages of device/service discovery, connection establishment, and service continuity. Correspondingly, cellular network may automate pairing of proximate devices, maintain their security, and improve the battery lifetime of D2D peers sharing their desired content. Continue reading

LTE-Assisted WiFi-Direct: Brno presentation - Part1

LTE-assisted WiFi-Direct is a promising technology that creates unprecedented benefits, for both operator and end user, at the stages of device/service discovery, connection establishment, and service continuity. Correspondingly, cellular network may automate pairing of proximate devices, maintain their security, and improve the battery lifetime of D2D peers sharing their desired content.

We have completed a full-scale practical trial of network-assisted WiFi-Direct on a live 3GPP LTE deployment in Brno, Czech Republic. This unique trial unites partners from Tampere U. of Technology, Brno U. of Technology, and Intel Labs US. This post presents the final presentation about this trail.
