  • Minnesota PublicSafety Broadbandand FirstNet BriefPrepared for:Governor’s Task Force on BroadbandOctober 16, 2012Presenter:Brandon Abley, DPS-ECN
  • Agenda1. Public Safety Broadband/LTE Basics2. FirstNet and a New National Model3. Minnesota’s Broadband Study4. Making a Business Case5. Unresolved Issues6. Next Steps for Minnesota 2
  • Introduction to LTE Technology• Next generation cellular standard• All Internet Protocol (IP) based• OFDM (DL) and SC-FDMA (UL) Air Interface• Flat architecture with more capable eNodeB’s• Use of Multi Inputs Multi Output (MIMO) antennas• Tens of megabits throughput and sub 50 mS latency • 10 band classes (incl. Band Class 14 for PS) and in seven bandwidths • Global adoption by dozens of commercial carriers including all major US carriers 3
  • LTE Performance Category LTE Performance• PSBL Block 5+5 MHz Bandwidth 10 MHz• D-Block 5+5 MHz Peak Downlink Data Rate Theoretical peak: 86 Mbps• Total 10 MHz in each Peak Uplink Data Rate Theoretical peak: 36 Mbps Estimated Avg DL Throughput 16 Mbps direction Est. Cell-Edge DL Throughput 0.5 Mbps• Estimated 3X more Est. Avg UL Throughput 9 Mbps spectral efficiency than 3G Est. Cell-Edge UL Throughput 0.3 Mbps VoIP Capacity 200 Users per sector• Varies based on antenna configuration – 2x2 MIMO – 4x4 MIMO• Highly variable based on signal to noise ratio 4 4
  • LTE Coverage Not Equal to LMRCoverage and Operations• LMR link budget is better than LTE at broadband speeds – 4G requires far more sites to match coverage – However, LTE could scale to non- broadband speeds• Significantly less cost per eNodeB than per LRM• More sites may increase operations budget versus LMR• Huge eNodeB backhaul requirements to Core 5
  • Architecture• RAN – Radio access network – Sites• EPC – Core network – Servers, gateways, switchin g, management• Applications – 3rd-party/neutral transport – Network-native 6
  • What is a RAN?Radio Access Network• UE (“User Equipment”) – These are user devices! – Cell phones, modems, etc.• eNodeB – These are sites! – They connect directly to the core network without intermediate controllers – LTE has a flat architecture and only IP connections 7
  • What is an EPC?Evolved Packet Core• Distributed Architecture• Not all traffic has to go through every network node• Well-defined interfaces (intended for) vendor interoperability• Some interfaces left open to vendor interpretation (by design)! 8
  • Why do we care?• Innovative new services through new applications• Make applications decisions independently of network decisions• Maximum communications interoperability; one network, one frequency; all systems can be interconnected• Enhanced situational awareness• NG9-1-1 traffic delivery to responders• Reduced long-term costs – Global standard shared by public and private (economy of scale) – Can offset existing costs spent on commercial services – Expanded public-private partnership capabilities• Better spectral efficiency (We are in a spectrum crunch!) 9
  • FirstNet and a New National Model
  • FirstNet2012 Middle Class Tax Relief and Job Creation Act• 700 MHz D Block to reallocated to public safety• First Responder Network Authority (new entity within NTIA) will hold public safety broadband license and be responsible for NATIONAL network deployment and operation – FirstNet board of directors will include federal, state, and local representatives (NTIA must appoint state/local members by August 20, 2012)• Up to $7.3 billion in funding for network from future FCC incentive auctions (NTIA can borrow $2 billion up front)• States can “opt-out” and deploy state networks (subject to FCC approval) Source: FCC Regulatory Update March 8 2012 11

  • FirstNetTransition• FCC to transition public safety broadband spectrum to FirstNet• FCC Technical Advisory Board for First Responder Interoperability – Develop technical requirements for broadband interoperability – Board recommendations submitted to FCC for review – FCC approves Interoperability Board recommendations and transmits them to FirstNet for adoption• Timing: – March 23 -- FCC appoints Interoperability Board members – May 22 -- Board must submit recommendations to FCC – June 21 -- FCC must transmit recommendations to FirstNet Source: FCC Regulatory Update March 8 2012 13
  • FirstNetFirstNet Duties and Obligations• Determine uses/access to network• Develop RFPs• Promote competition in the equipment market• Receive payment for use of FirstNet’s spectrum/infrastructure• Consult with States on State & Local Planning• Leverage existing commercial or other infrastructure (e.g, ARMER)• Develop/sponsor national standards and requirements• Represent Public Safety before standards bodies Source: Alcatel-Lucent, “FirstNet: Implementation Timeline & Requirements”, March 2012 14
  • FirstNetFirstNet Duties and Obligations (More)• Creating the over-arching strategic framework for the public safety network• Ensuring nationwide standards for use and access to the network based on commercial standards• Working to deliver economies of scale for public safety• Maximizing opportunities for long-term cost savings and improved functionality• Integrating federal first responders and public-safety-related uses to maximize the efficiency of the new network• Formulating a fee collection system that reflects market reality and ensures FirstNet self-sustainability Source:http://www.ntia.doc.gov/files/ntia/publications/firstnet_prospectus_-_final.pdf 15
  • Timeline FCC 30 Days (March 23) Minnesota/SRB Interop Boardplanning activities Creation of State & Local 6 Months FirstNet Implementation Grant (August 20) FirstNet ?? (No deadline) RFPs NTIA/Governors ?? + 90 Days)Minnesota PublicSafety Broadband! State ?? + 180 Days) FirstNet Deploys Opt-Out Some information from: Alcatel-Lucent, “FirstNet: Implementation Timeline & Requirements”, March 2012
  • FirstNetWhat is “Opt-Out”?• State opts to do its own RAN build-out• The state’s network is still part of the national network• The state still pays access fees to FirstNet spectrum• The state may be required to still pay fees for national core infrastructure, or may be barred from buying its own core with Federal funds• The state is not excluded from national funding if it opts out• Opt-out plans subject to regulatory approval and must demonstrate a compelling economic case• Opting out means states can pursue novel/innovative partnerships 17
  • Core Functions: Findings With FirstNet model, these “core” services are not owned by any state/local government. 18
  • MinnesotaBroadband Study
  • FindingsSection 1: User Needs AssessmentData collected through:• Face-to-face interviews (hundreds of man-hours’ worth)• Online survey (175 respondents)• Included use cases, equipment/applications needed, and a tabletop exercise 20

  • Findings 34
  • Actual Throughput Findings • Actual LTE throughput at each site can be as high as 8500 kbps with 5x5 MHz; double that with 10x10 MHz • Various factors degrade actual throughput, so statewide requirement is actually a fraction of peak performance • Sectors are unlikely to perform at peak performance most of the time for technical reasons (adaptive modulation, intra- system interference, others) 35
  • Note: Throughput rates Findingswith 5x5 MHz Channels (i.e. without D Block) 36
  • Preliminary Network Designs: Findings“ARMER” 380-site Transitional Design ARMER Only – Broadband Speed • Avoids 141 tower builds • 94% statewide mobile coverage (lt. green) • 28 counties < 95%, E.G.,: – Cook: 78% – Winona: 82% – Lake of Woods: 86% – Lake: 82% ARMER Only – Dial-up Speed • LTE can scale down to lower rates in the yellow areas • > 95% statewide coverage • 4 counties < 95%: – Cook: 92% – Winona: 93% – Lake of Woods: 91% – Lake: 94% 37
  • Findings 38
  • FindingsSection 5: Funding Models• Three models covered• To range the gamut from fully state-owned (like ARMER; “opt-out” scenario) to carrier-ownedModel DescriptionState Public Model The State builds, owns, operates, and maintains the network. This is analogous to land-mobile radio deployment in the past, such as ARMER.Vendor-Financed Model A vendor fills in financial shortfall for building and operating the network by making commercial usage available to the network.Commercial Carrier Model An existing carrier augments it network to meet public safety needs. 39

  • Phase 2Phase 2 Broadband Study “Plan the Plan”• To develop a process for: – Compiling the data needed by FirstNet to design in MN – Compiling the data needed by stakeholders to join NPSBN• To Identify gaps in – Governance – Statewide planning – Sustainability – Support needed by FirstNet• To create a basic Minnesota public safety broadband plan template to empower stakeholders to make “the big decision” 41
  • Making a Business Case
  • Making a Business CaseAn LTE Network is Useless!• A network, by itself, does absolutely nothing• The value of the network is determined by: – The services it provides – The services that users can provide for themselves – The ability for the network to deliver those services – Potential for consolidation and cost center mitigation• The national model provides us with a means for basic connectivity, but as of yet, there is no real business case• To make a decision and to interact with FirstNet, the state needs a business case for the network 43
  • Making a Business CasePotential Assets in Minnesota:• Commercial service offsets (cellphones, network, internet access)• Private partners – Users: Utilities, rural communities, general government ($$ generation) – Providers: Telcos, cellular companies, ISPs ($$ savings)• Hosted applications (CAD, CPE, logging, LMR, productivity)• Incumbent private public safety communications systems• Incumbent government (agencies, funds, technical staff, leadership)• Pre-existing infrastructure (ARMER, locally-owned fiber)To make a business case, we should focus on offsetting existing costs first, then exploring new and added value. 44
  • Making a Business CasePublic Safety is Local• The role of state and Federal government in public safety is somewhat limited – All incidents are local incidents – Some incidents are state or Federal incidents – E.g., ARMER: <25% of system users are state or Federal responders• We cannot justify a network of this size without comprehensive support from local government• Minnesota’s—and the nation’s—business case must be palatable for local government to ensure participation 45
  • Making a Business CaseHow Much Will it Cost?• Estimates vary; if we extract estimates for Minnesota to all 50 states we can expect: – CAPEX: Over $16 Billion – OPEX: Over $795 Million• FirstNet bill provides up $7.3 Billion; most likely won’t cover even HALF of CAPEX• FirstNet bill provides no OPEX, but gives FirstNet the authority to collect fees to support operational expenses• Unlikely that government at all levels will generate new revenues at these levels; better to focus on cost savings and efficiencies 46
  • Unresolved Issues
  • FirstNetState Planning Funding• State grant funding guidelines required to advance the planning strategy• State assets analysis during the planning phase (tower, fiber, data centers, POPs)FirstNet Network Deployment• What is the role of states and local jurisdictions in developing the implementation strategy?• How will the network deployment strategy be prioritized?• What FirstNet service level agreements are to be proposed and are the network coverage objectives?• How will the cost of service be determined?• Who are the authorized public safety users?• Is FirstNet pursuing national or regional partnerships for revenue sharing?• What is the schedule to auction spectrum to fund the build out?• What is the balance of the FirstNet proposal compared to an Opt-Out strategy? 48
  • Next Steps
  • Next StepsSRB/SCIP Broadband Action Items:1. Establish a statewide body under the Statewide Radio Board to sanction public safety interoperable data planning activities2. Develop a full assessment of assets to contribute to the network3. Develop a Minnesota Public Safety Broadband Plan4. Develop applications and data interoperability standards5. Investigate potential formal partnerships6. Continue to foster interoperability planning on a regional basis7. Monitor, and participate when appropriate, in larger planning and standards-setting 50
  • Next StepsProgress Snapshot, October 2012:• Goal 1: SRB has established interoperable data committee, representing varied public safety and private interests.• Goals 2 and 3: Project to establish framework for public safety broadband plan underway. A core component of this plan is a detailed inventory of assets to assist local governments in making a business case.• Goal 4: Minnesota participation in national efforts to set nationwide baseline requirements for the NPSBN through professional organizations (NPSTC, etc)• Goal 5: Private partners to be included as stakeholders in the state broadband plan• Goal 6: Minnesota work through RECCWG; region-wide joint filings with NTIA/FCC on public safety broadband issues• Goal 7: Minnesota representation in workgroups through NPSTC, APCO, etc. 51
