1 Beyond 5G: Toward the Terabit Wireless Era Dr. Emilio Calvanese Strinati Smart Devices & Telecommunications Strategy Program Director CEA-LETI Dr. Laurent Dussopt Smart Devices & Telecommunications Scientific Director CEA-LETI

2 Whyare wetalkingabout Beyond 5G Standards are not ready yet(3g PPP, ETSI, etc ) Regulation(spectrum, drones, for instance) not in favour yet [ ] Technologyisnot mature or toocosty(mmwat very high frequencies) 5G discussion bodies has choosendifferntpathsand prioroties(ex. VLC) The needfor suchtechnologyisnot hereyet Wejustsimplydo not how to do itnow

3 5G Unlicensed mmwbands mmw: defined between 30 and 300 Ghz unlicensed band: 60 GHz (57-66GHz) band Light-licensed E band: GHz, GHz Huge spectrum opportunity beyond 6 GhZ! Figure: main frequency bands for wireless communications between 2 and 90GHz

4 5G Vision (in short) Today 5G targerts(among others) Very high dense deployment with consequent shorten connection range Very high (wireless) capacity(access, Xhaul): Gb/s Verylowlatency Distributed access Scalability Enabling technologies (amont others): Very compact and massive MIMO antennas and related beamforming and very high directivity Very high spectrum usage (mmw) Larger communication bands Mobile edge cloud

5 Future CapacityNeeds: Tb/s (wireless) Applications and services beyond2020 willrequire1tb/s wireless connections Reference: G. Fettweis, System Concept for 1 Gbit/s and Beyond, Tutorial IEEE 802 Plenary, Vancouver, November

6 Future CapacityNeeds: Tb/s (wireless) 1Tb/s: need a large amount of contiguous bandwidth suitable for communications over short GHz: up to 100 GHz bandwidthavailable! Do not be scared: atmospheric attenuation is not a significant for short distance (small cells 250 GHz up to 10 m access range

7 Opportunity: Spectrum for 1Tb/s 220 GHz 100 GHz 100 GHz Jonathan Well, Faster Than Fiber: The Future of Multi-Gb/s Wireless, IEEE Mircrowave Magazine, May 2009, pp

8 HW AT HIGH FREQUENCIES: TECHNOLOGY WILL BE READY!

10 To Conclude Today mmwlinks have the potential to meet the capacity and latency requirements needed by the backhaul and small cells of the Future Networks. SiGe technology is ready to be used in mmwlinks, having today technology and prototypes available at mmw Bands Bands beyond6 GhZare an excellent cost effective enabler to deliver 5G Networks and Services Tomorrow (almost today!) 60 GHz expected to be deployed in terminal for D2D and WLAN (WiGiG/802.11ad) connectivity => dual use of same hardware in terminals for ad-hoc short-range connectivity / cellular access. WRC'18 discussion on regulation for new spectrum beyond 6 GhZis needed Opportunity to converge worldwide on decision for new spectrum allocation

11 To Conclude H2020+ Even Higher in Frequencies: GHz presents interesting potentials that need to be explored Envisioned coverage range 10 to 12 meters 1 Tb/s Do not be scared: atmospheric attenuation is not a significant for short distance (small cells 60 GhZup to m access 250 GhZup to m access range Which are the challenges?
