LTE-assisted WiFi-Direct is a promising technology that creates unprecedented benefits at the stages of device/service discovery, connection establishment, and service continuity in 5G ecosystem.
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 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
Inspired by rich potential of assisted D2D, and building on our recent rigorous research in this area, we have decided to work this summer to comprehensively demonstrate this promising technology and conclude on its practical benefits. Along these lines, we are completing 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.
A short video about our LTE deployment and implemented LTE-Assissted WiFi Direct system is available here.
At the end of the trial, to discuss the lessons learned and decide on the way forward, we have conducted a summary seminar at Brno U. of Technology, Brno, Czech Republic. This seminar has brought together selected representatives of mobile network operators, service providers, vendors, and manufacturers, who engaged into fruitful discussions on the potential of LTE-Assisted WiFi-Direct as well as its capabilities to enrich applications and services in current mobile ecosystem.
The summary slides of the seminar are available for download here.
