3 PSBN Use Cases Law Enforcement Streaming video Eg Ability to stream live from an in car camera back to a station or EOC during disaster. Watch live stream from a helicopter down link. Watch live stream from a bank robbery during a response to a robbery alarm. Upload of video from in car video and/or body worn cameras Eg instead of transferring with thumb drive or until arrival in wifi hot spot area. Learning Management Systems Eg view training in the field and take an online test. Streaming of training videos and messages Eg available training videos, video messages from the Chief or Sheriff. Refreshing data content and/or baseline image on Mobile Data Computers Eg MDC baseline updates, security updates, updated criminal information, maps, etc. Voice over IP Eg plug a USB headset into a MDC and use as an extension in a private phone system. NOTE: cellular carriers are starting to enforce 5GB limits on public safery LTE data use (unlimited accounts) which will come at a significant higher cost. Copyright 2014, LA-RICS Authority.

7 Public Safety Broadband Network Benefits

8 Why The PSBN? Public Safety Grade Public Safety Grade = Higher Network Availability Power Battery Backup 8 hrs. Generator Backup, up to 72 hours fuel Microwave Backhaul Redundant paths or components % availability for each link Components Guaranteed levels on major components Robust Class III towers The network is available when it s needed most during natural and man-made disasters Copyright 2014, LA-RICS Authority. All Rights Reserved. 8

9 Why the PSBN? Public Safety Controlled Public Safety Controlled = Higher Service Availability Dedicated Capacity Avoids congestion of public and media during incident Operational Fully informed on system performance, outages, maintenance Establish restoration priorities Quality of Service Public Safety decides on device and application priorities Pre-emption of lower priority services if necessary Emergency Deployable Control Service is available when it s needed most during very high levels of public data consumption Copyright 2014, LA-RICS Authority.

10 PSBN Overview

11 LTE and Motorola Team Overview 3GPP = Third Generation Partnership Project Global participation, most of world s cell phones use their standards Long Term Evolution (LTE) 224 global carriers (1) 126 million global connections (1) Team Motorola Motorola Solutions: Leader in mission critical, public safety systems Ericsson: Leader in LTE infrastructure General Dynamics: Leader in wireless communication site infrastructure (1) Source: 4G Americas Copyright 2014, LA-RICS Authority.

12 Available Throughput LTE Performance Considerations LTE (typ.) uses the entire spectrum block in three sectors at each site Cells constantly adjusting power based on need to manage interference LTE range is lower than LMR (250 milliwatts versus 5 watts) Amount of capacity available to a single user depends on a variety of factors Available spectrum resources Signal level Interference levels LTE has robust Quality of Service (QoS) capabilities to manage resources Pre-emption Priority Applied by user (device) or application Category Peak Downlink Data Rate Peak Uplink Data Rate Est. Cell-Edge DL Throughput Est. Cell-Edge UL Throughput LTE Performance Theoretical peak 86 Mbps Theoretical peak 36 Mbps 0.5 Mbps per user 0.3 Mbps Source: NPSTC BBTF (10 MHz Channel) 25% Cell Resources 4 % Cell Resources Far Cell/Low SNR Near Cell/High SNR Copyright 2014, LA-RICS Authority.

13 Proposed Contract Coverage IP Layer throughput at cell edge: 768 kbps downlink (1) 256 kbps uplink (1) Outdoor, portable coverage (2) (3) Covered area varies per zone, different area for uplink and downlink New Zone Added (Foothills Developed) Copyright 2014, LA-RICS Authority. All Rights Reserved. LA-RICS Coverage Zones Percent Zone Coverage Downlink (768 kbps) Uplink (256 kbps) LA Basin Santa Monica Mts Angeles Nat. Forest Foothills Foothills - Developed CA-14 Corridor Northern Desert Waterway (1) LTE scales higher and lower than these rates (as low as 32 kbps and over 30 Mbps) (2) Indoor coverage is possible at lower throughput levels and nearer to cell sites, but is not guaranteed. (3) Mobile coverage footprint is larger. 13

14 Base System County Wide Coverage 25% Loading* 95% Covered area reliability Portable on the Street Minimum Data Rates DL 768 kbps (Green) UL 256 kbps (Orange) System Sized At Very High Usage 9 GB per Month per user* 100,000 users (50% Active) Coverage and Traffic Profile capacity increase with less users* *Concepts discussed on upcoming slide Copyright 2014, LA-RICS Authority.

20 Discussion and Recommendations Regarding Technology and Operational Options

21 Summary of Items For Consideration Additive Alternate 1 - Home Subscriber Server Essential database and AAA function Additive Alternate 2 - Redundant Evolved Packet Core Geographically redundant EPC Additive Alternate 3 - Location Services GPS and network assisted location information System Refresh Background: The Evolved Packet Core is essential for operations all traffic must flow through the core Primary core at FCCF has redundant elements and high availability FirstNet eventually has the responsibility to deploy cores and core services FirstNet core schedule and scope is not publicly available Copyright 2014, LA-RICS Authority. All Rights Reserved. 21

23 Additive Alternate 1 HSS Discussion Benefits of Exercising AA No risks associated with proceeding with project (independent of FirstNet schedule slippage) Can conduct special ops test, optimization, coverage testing. Benefits of Not Exercising AA If leveraging FirstNet HSS, no integration challenges associated with interoperability reduces complexity and improves access to other FirstNet services Avoids potential stranded investment Potentially reduces operations costs by $16,561 per year Copyright 2014, LA-RICS Authority. All Rights Reserved. 23

24 Additive Alternate 2 Redundant EPC Discussion Benefits of Exercising AA Geographically redundant EPC immediately available at launch Capable of continued operations with failure(s) at FCCF public safety grade Capable of sustained operations during operations Benefits of Not Exercising AA Reduces operational costs by $724,046 per year Avoids stranded investment (FirstNet may relocate the redundant core) Potentially leverage hosted core from Motorola or other alternative Load balancing Copyright 2014, LA-RICS Authority. All Rights Reserved. 24

25 Additive Alternate 3 Location Services Discussion Benefits of Exercising AA Network based location services available to locate without GPS access (receiver or satellite visibility) Benefits of Not Exercising AA Reduces operational costs by $430,399 per year Avoids stranded investment (FirstNet likely to deploy location services, may not leverage LA-RICS implementation) May have more capabilities that are more tightly integrated with other nationwide services Note: Agencies running AVL can still operate those apps over the PSBN Copyright 2014, LA-RICS Authority. All Rights Reserved. 25

26 Financing Option System Refresh Discussion System Refresh enables budgeting of system replacement during the useful life of the previous system FirstNet will own responsibility to build, operate, and maintain public safety broadband network at some point Unclear which assets (and their maintenance costs) may be transferred to FirstNet Towers, Backhaul Equipment, LTE EPC, LTE enodebs, Generators: All assets expected to have a useful life longer than the period when FirstNet would take them over (10 year life minimum, 5 year FN operations) Copyright 2014, LA-RICS Authority. All Rights Reserved. 26

27 Contract Recommendation Discussion Committee Chairs and LA-RICS staff feel the PSBN provides a substantial emergency response benefit Opportunities remain to reduce operations costs further Increased use of Member facilities Collaboration with FirstNet to take on operations costs for core Phase 1 NTP requires no additional funding from members Schedule has no additional time to accommodate continued study and many issues can be resolved during design phase Phase 1 period allows more opportunity to identify symbiotic secondary users Copyright 2014, LA-RICS Authority.
