2Future of Spectrum Sharing The 40th Anniversary Marconi Society SymposiumOctober 2, 2014Janice ObuchowskiPresident
3Economic Growth Doesn’t Just Mean Commercial Wireless Services, Sharing Is the FutureHuge demand for ready access to broadband spectrum capabilitiesDemand will continue to increase – 1000x more traffic - 100x more connected devices than todaySharing is not only advisable – it is inevitableRelocation will be increasingly complex and fraught with diminishing returnsArbitrary numerical goals (e.g., 500 MHz) will lose meaning as spectrum exclusive “ownership” fades in importanceThe “Internet of Things” will blur the identity of “incumbents” and emphasize fluid spectrum accessNetworks will become more flexible as we move away from operator-centric modelsSharing will be bi-directional, multiplying avenues for spectrum access by more users (including Federal): two-way sharing cited in Presidential Memo, DoD EMS StrategyEconomic Growth Doesn’t Just Mean Commercial Wireless Services,It Relies on a Whole Universe of Spectrum-Dependent Equipment & Services
4Fully Realized FutureThe 2025 and beyond sharing paradigm will be based on:Greater efficiency of spectrum usage;With denser deployments and use of more (higher and lower) frequenciesImproved antennas & transmission technologies;Dynamic Spectrum Access (DSA) components will underpin sharingSmart database technologiesDedicated sense-and-avoid networksCognitive radios and networksFoundation for Future Sharing World Will Come From Work Today: Many sharing issues still need to be worked out. Current Domestic and International work is key to making that happen.
5Technology Development More spectrally-efficient standards – “5G”Beyond LTE – 5GPPIEEE – (ax), (TVWS), (WPAN), etc.Dedicated Listening Devices (DLDs)Database technologiesCognitive radio systems (CRS) and networks (HetNet, SON)Antenna systems – MIMO, etc.Power Reduction; improved batteries; lower network power requirementsFurther small cell development (“WiGig” - up to 6 Gbps connections enable ubiquitous wireless displays)Technology is the Achievable Part; the Human Quotient Is HarderRegulatory issues: enforcement and international harmonizationSocial and values issues: While technology moves ahead,we lag behind in coping with the Internet’s unintended effects
6Avoiding `Magic Thinking’ Let’s benchmark today’s reality:Spectrum policy conversation has been transformed by diverse stakeholders embracing sharing –carriers, Federal users, unlicensed players. Desired sharing terms and conditions for sharing vary among these players. While sharing is an optimal path forward, it’s hard:Cognitive networks are still being developedTechniques like DFS are not universally trustedThere is no global regulatory approach to sharing, or even consensus in the U.S.Sharing today is negotiated band-by-bandPainstaking process of compatibility studiesNational and Intl. negotiations among industry and government stakeholdersEstablishment and testing of technical standards and regulatory restrictionsCore telecom services still rely on carrier netsOpening door to sharing opens up new business models, new players, new paths to competition to emergeMix of protected infrastructure, lightly regulated competitors and unregulated appsChange will involve trade-offs in security, reliabilityWe have 21st century technology with 1970s enforcement
7Regulatory Experimentation National-LevelTVWS and incentive auctions (UHF bands)Small cells and local coverage (3.5 GHz)Completing a broadband spectrum range (5 GHz)Licensed Shared Access (LSA)International-LevelOther countries -- UK, EU, etc.ITU-R – Ongoing studies for WRC-15 & Study Groups (e.g., WP1B & 5A).Many countries remain wary of TVWS, DSA experimentsSharing poses risks and opportunities, and both sides of the equation are still being proven out, requiring a ‘trust but verify’ approach.NTIA-DoD National Advanced Spectrum and Communications Test Network is among efforts working toward technical validation of new forms of sharing to create trust among stakeholders.What’s Good for the Goose: So far, terrestrial mobile industries seem interested in sharing Federal and broadcasting bands – what about opening up non-Federal, commercial wireless bands to sharing?
8Open Questions: Security, Monitoring and Enforcement Solving Security, Monitoring, and Enforcement issues around sharing will require evolution of policy, regulatory, and technologyGreater spectrum abundance ≠ greater stability or less interferenceSecurity and Cyber-SecurityIndustry is evolving protections for consumers; meanwhileDatabases geared toward Google customers are not designed for OPSECMonitoringOpportunities in IoT devices as sensorsEnforcementGreater centralized network controls could helpDecentralized networks may require technology to avoid causing harmful interference and being more resilient to changes in the spectrum environmentSharing only works if all parties comply – otherwise, you have “tragedy of the commons”What about purposely low cost devices, without sense and avoid or shut-down features?Google puts advanced encryption in handsets; law enforcement up to and including Attorney General object. What about law enforcement and homeland security?Trust and Enforcement as always are Key!
9Snapchat was recently valued at roughly $10 billion, More Spectrum for What?Demand Driven by Education, Health, the Arts but…Consider these social media apps:Facebook – complicated privacy settings and potential over-sharing of personal infoSnapchat – messaging of “disappearing” photosSecret – Allows short, anonymous messaging among small user groupsWhisper – Users can send anonymous messages superimposed on imagesYik Yak – This app has no usernames or passwords, but allows all users in a 1.5 mile area to send and read messages anonymouslyHighlight – provides social and background information on users to all other app users up to 100 yards away.Tinder – A location-based dating app with chat capability that provides personal info to other nearby usersSource: Arlington Catholic HeraldAnd we wonder how teens are exposed to “sexting,” cyber-bullying and stalking?Families are facing these potential digital dangers aloneSnapchat was recently valued at roughly $10 billion,And it reportedly rebuffed an acquisition offer of $3 billion from Facebook
10Unintended/Intended Consequences Values Issues – the Digital `Wild West’The good, the bad and the ugly – everything from cancer support groups to porn & cybercrimeHow do we protect the vulnerable and make knowledge out of information overload?Economic Growth and the Public GoodIn most cases, they coincide – BUTSharing just to meet growing consumer demand may risk cutting off future spectrum access for growing Federal and non-profit needsDigital Dividends and Digital DividesAre we entrenching broadband mobile as an amplifier of global digital disparities?Need to empower the world’s less-affluent to engage in the Information AgeSharing DividendSharing creates new opportunities for more wireless bandwidth to be utilized by more users, so the question is how that "sharing dividend" is apportionedCommercial broadband sometimes – but not always - the highest and best useNumerous public interest applications may be optimal use (e.g., air traffic control, space exploration) – still important economic contributions and often no commercial/wireless carrier substitute.
11The vision of a technologically enabled mobile marketplace will be a reality in Our challenge is in ensuring that it works for the maximum possible public good.Janice ObuchowskiPresident
