12 Open-source for 5G Economics of mobile are changing towards a Commoditization of RAN Cloud SDN/NFV (OpNFV, JuJu + Ubuntu OpenStack + MAAS) Emergence of OpenStack in vicinity of RAN Lots of (cheap) open-source hardware starting to emerge More generic computing equipment right down to PHY (x86/ ARM) (even maybe PHY) h openbts, OpenAirInterface Canonical (Ubuntu!) providing orchestration and OS solutions (at least for prototyping today) for cellular networks Example OAI: Full experimental LTE implementation (Rel 10) h real time and with interworking functions: EUTRAN, EPC, UE h RAN + EPC in Ubuntu JuJu OpenStack offering! F In a position to provide a full LTE network with VoLTE in 2015! Open-source end-to-end (OAI EPC, ClearWater IMS, FreePCRF)

13 Open-source for 5G Emergence of hackers in radio networks (or leveraging their work) YatesBTS, Fairwaves: deploying commercial 2G nets based on opensource radio HW and SW Emergence of fully functional 4G solutions on equipment that can be bought at the supermarket (almost, with a bit of help from National Instruments or Lime Microsystems) Or from Crowdfunding projects (e.g. Novena-RF) Mainstream 4.5G/5G will need cheap, easily extensible devices at the edge (for below 6 GHz systems) small (cheap) form-factor but ubiquitous high-quality RAN access Example: cheap RRH with CloudRAN (Rel 12 RRH, 25 dbm < 500 euros) commodity Ethernet solutions instead of CPRI, sampling synchronization is an issue, but solvable Support potentially of dynamic switching between RATs in the same RRH DSP split between RRH and BBU for fronthaul optimization Mobile Edge Computing (ETSI MEC ISG) provision IT and cloud-computing capabilities within the radio access network (RAN) in close proximity to mobile subscribers h compute/storage able to perform functions such as content delivery, low-latency IoT functions h edge or at least RAN-aggregate and process IoT data from a range of media (both cellular and non-cellular) Mix of cloud and RAN technologies (RRH-to-DataCenter approach)

14 Next Steps for OAI Ensure a path 4G 5G through open-source policy Reference implementation of Rel 13/14 5G Work with new carrier candidates now (e.g. UFMC), short packet low-latency carriers, contention-based access VRAN, NFV, MEC architectures Rapidly-deployable EPC/eNB (with LTE or other backhaul) Serious contributors from outside Eurecom Combination of hackers, academics, SMEs and major industry OAI Software Alliance launched at the end of 2014 «ready to use» for anybody on commodity hardware (PCs + National Instruments) and industrial platforms! GPLv3 APACHE v2.0 More global adoption for innovation and research (Vendor labs, University Labs, etc.) common tool between industrial and academic research Can also be used in 3GPP process for study items Business adoption in test/prototyping market

15 Anybody can build a 4G/5G network Serious contributors from outside Eurecom Software Alliance ( Fonds de Dotation ) around the current OpenAirInterface.org development Make trusted environment Contributors and users need to secure themselves Clear open source rules Any individual person or non-profit organization can become a member for free Membership conditions for companies Increase quality & simplify access Simple and well described binary build procedures for all the LTE components Friendly to various RF systems (RRH, SmallCell, etc.) Anybody can build a fully open-source 4G network comprising a couple of enbs + EPC for less than 10K and 1 human week of effort

16 Example Membership Models (a la OpenStack/Eclipse) Strategic members ~100k per year (reduced to 40k with agreed effort) Strong voice in decision process (limited number of members, e.g. 8) Ability to run projects (e.g. porting for industrial HW targets) Ability to attend and host meetings Associate members ~10k per year, free for non-profit organizations limited voice or no voice in decision process (only if merit warrants this) Use of logo / SW certification Attend meetings Ordinary (Individual) members Free Main workforce, can commit to codebase Can attend meetings and join projects

19 Conclusion OAI is all software, all IP, and open Integrated tools for a complete experiment life-cycle Flexibility to architect, instantiate, and configure the network components (at the edge, core, or cloud) E.g. The network can be packed into a single commodity server/ PC or virtualized as a cloud service Rapid prototyping of 3GPP compliant and noncompliant use-cases E.g. Software-define networking or mobile edge services 19
