Session Summary

Presentation Highlights

  • Ingrid Moerman (iMinds): Experimental facilities should not only offer hardware infrastructure, but also software platforms with unified programming interfaces for flexible and intelligent control of radio and network settings, together with technical support to experimenters. There is an evolution of wireless experiments, moving from academia to industry (mainly SME) and in some (limited) cases also the end-users.
  • Luiz DaSilva (Trinity College Dublin): Wireless networks of the future will be virtualised: virtual wireless access network will feel to the user like a traditional network operated by a single entity, but is in fact orchestrated out of a diverse pool of resources with different ownership models. Main challenges are: How to select physical resources to meet the needs of a virtual operator? How to dynamically manage these virtual networks? How to ensure security, and privacy? What economic and public policy models will support this new model?
  • Raymond Knopp (Eurecom): Today the cellular world is closed, impeding real impact from Academia to 3GPP. The future wireless world will be characterized by software radio, flexibility, commoditization of real-time RF and open source; a world where the open-source community will have impact and can introduce disruptive technologies.
  • Ivan Seskar (Rutgers University): In order to deal with 5G technical challenges (mixed environment, CRAm with NFV and SDN, massive/cooperative MIMO, real-time issues, etc.), FPGA programming skills are required, while today there is no expertise with programming of large FPGA in academic world.
  • Suman Banerjee (University of Wisconsin-Madison): Paradrop offers a virtualization framework that moves the cloud to the home router and drops 3rd part apps & services on demand. Paradrop avoids the typical problems associated to cloud-based networking, like disruptions and network viability.
  • Kobus van der Merve (Univeristy of Utah): PhantomNet is an open programmable end-to-end mobile testbed that integrated OpenEPC with Emulab to enable research at the intersection of mobile networking, cloud computing and software defined networking.
  • Yahya Al-Hamzi (Fraunhofer Fokus): 5G Playground answers industry experimentation requirements addressing multiple uses cases: Interoperability (providing a common ground for product development), Product prototyping (using parts of the 5G Playground software for developing PoC prototypes for new products), Remote experimentation (using the Fraunhofer FOKUS Facilities), calibration and benchmarking (customizing prototypes and products for the specific market).

The following issues were raised during discussion:

  • Real-time requirements of software radios are particularly challenging for WiFi technologies (order 10 μs inter frame spacing versus latency requirements of order ms for LTE)
  • There is an increasing interest in SR (Software Radio) platforms. However, today software radio ends at the base station (at the LTE eNode B), while there is an increasing demand for smaller, low-power SR platforms for UE (user equipment) developments (e.g., LTE-unlicensed)
  • Main challenges for experimentation with SR platforms are: dealing with many (500+) GPP cores, clock distribution, high-performance computing, finding researchers with FPGA programming skills
