4 1 Executive Summary 1.1 Introduction Blue Wing Services, in affiliation with Shulman Rogers Gandal Pordy & Ecker, P.A., ( Shulman Rogers ), provides a final report for the Radio System Analysis to Knox County, Tennessee. This report is a result of collecting, reviewing, and analyzing information pertinent to Knox County s efforts to upgrade its Public Safety radio system. During the project, numerous stakeholders were contacted and interviewed. In person meetings and updates were held at various points throughout the project. All participants to this project have been extremely helpful, with a willingness to provide any and all information they possess about the radio system upgrade effort for the County. Blue Wing and Shulman Rogers wishes to commend everyone for their dedication and hard work, and thank everyone for their contributions to this project. 1.2 Methodology and Approach An objective analysis was conducted to identify the best overall radio systems solution for the Knox County Emergency Communications District (KCECD). This analysis was intended to determine if the negotiated contract with Harris Corporation or the Motorola-provided TVRCS approach best meets the needs as outlined in Request for Proposal (RFP) 1914, Wide Area Radio System. Blue Wing has applied the proposed methodology that aligned with the County s guidelines. Our approach was divided into three segments, they were: Comparative Analysis Data Collection Review of Collected Data Comparative Matrix and Reporting Comparative Analysis Data Collection It was vitally important to KCECD that all aspects of this transitional decision be considered for analysis. Close consideration was given to aspects of, governance, ownership, subscriber functionality and participation costs, and overall economic feasibility. With this in mind, Blue Wing collected and compiled a large volume of data for review and analysis. Final Report 4 Blue Wing Services

5 The TVRCS radio system submittal provided by Motorola was obtained, as well as numerous supporting documents. These documents provided information about the TVRCS option, and its system attributes, such as coverage/propagation data, capacity, and system features and reliability. The Harris Corporation Proposal, Request for Proposal 1914, Wide Area Radio System, and all other proposal submissions that have been received were also collected and compiled for review. Teleconference meetings and in-person stakeholder interviews were held with Knox County personnel, State and Local public safety end users, agency managers, radio network and 911 Center Call Center Operators, emergency coordinators, public works stakeholders and the overall radio network user population. Local and cross-jurisdictional interoperability (City, County, and State) was also explored and collected Review of Collected Data Data collected via teleconference meetings and in-person stakeholder interviews was compiled into summary reports and included in relevant sections of this final report. The interviews were composed of constituent questions specific to the individual position and responsibility. A cross-comparison of the Harris radio system proposal and TVRCS radio system submittal was performed using the RFP 1914, Wide Area Radio System, as the baseline for the County s requirements. This final report presents information on each option using the structure and content of RFP In this way, KCECD will be able to consider its final decision based on familiar criteria previously deemed vital to current and future Public Safety requirements. These cross comparisons are reflected in the matrices and in the tables for each section of this final report Comparative Matrix and Reporting Blue Wing has interpreted the collected data and developed a matrix that presents and prioritizes the findings to identify any potential advantages and/or disadvantages associated with the Harris Contract and/or use of the TVRCS. Our Comparative Matrix addressed five (5) categories that are considered key to providing a comprehensive analysis. The five (5) categories for our review are: Technical Management and Governance Growth and Enhancements Final Report 5 Blue Wing Services

6 Costs Timeline Blue Wing is presenting this Final Report in fulfillment of its obligations to review and provide guidance on the County s decision for its next generation radio system. 1.3 Conclusions and Recommendations The RFP developed by KCECD was used as the requirements benchmark for our comparative analysis. In general, we found the RFP to be reasonably well written and captured the necessary system requirements to provide public safety grade radio communications to the Knox County Emergency Responders. Both the Harris county-owned system and the TVRCS system submittal offer comparable coverage, capacity, and basic feature sets for Emergency Responder communication. Although the TVRCS submittal provided by Motorola was much less comprehensive than the Harris proposal, both options provide the essential public safety communications capability that are seen in the industry today. On the surface, the TVRCS system option seems to have three significant advantages for Knox County, wide area regional coverage, interoperability and cost. The TVRCS option would allow for a Knox County Emergency Responder to travel outside his/her county jurisdiction and maintain radio communication with Knox County Dispatch. During interviews that were held, this need does arise on occasion for a number of radio users. TVRCS also provides for interoperability with neighboring counties and cities who also operate on TVRCS. Finally, the system base price for each option appears to present the fact that the TVRCS option is less expensive (TVRCS base system price is $4,299,520 vs. Harris base system price of $5,106,290). The perception is that this lower cost will result in greater coverage and interoperability for Knox County Emergency Responders. However, our analysis has resulted in conclusions that are different from what may appear to be true at first glance. As detailed in Section 7 of this report, the true lifecycle costs of either radio system option must be considered. For our analysis, an eleven-year lifecycle was applied, based on the County s requirement for one warranty year, and ten maintenance years of support. Over the eleven-year lifecycle, the TVRCS is actually more costly than the Harris county-owned system option, by approximately $934,467. Further, if the TVRCS option is chosen, Knox County 911 will not charge a radio system user fee of $28 per radio, per month. This lost revenue adds up to a total of Final Report 6 Blue Wing Services

7 $1,997,072 over the eleven-year lifecycle. Therefore, when all aspects of system costs are considered, the TVRCS option will cost Knox County more over the lifespan of the system. The TVRCS option has the potential to be more limiting with than a Harris countyowned option. Knox County would need to negotiate the system management functionality with TVRCS, and sign an amended MOU reflecting what was agreed to. Without a negotiated amended MOU to review, it is impossible to say if the TVRCS option truly limits system management functionality, but the potential exists. It is our recommendation to Knox County that the Harris county-owned radio system option best meets the requirements of the RFP and is the best value. The Harris radio system option is less expensive over the eleven-year system lifecycle, and provides more system management functionality. Interoperability and regional radio coverage can still be obtained by other means than tying into the TVRCS master site. Motorola APX radios, as well as other vendor radios, can still be purchased off of state contract and used on the Harris county radio system, so Knox County agencies will still have a choice for mobile and portable radios.

This report is a result of collecting, reviewing, and analyzing information pertinent to Knox County s efforts to upgrade its Public Safety radio system. This project has taken 30 days to complete. In that time, over 2,200 pages of documentation were reviewed, compiled, and analyzed. Numerous stakeholders were contacted and interviewed. In person meetings and updates were held at various points throughout the project. All participants to this project have been extremely helpful, with a willingness to provide any and all information they possess about the radio system upgrade effort for the County. Blue Wing and Shulman Rogers wishes to commend everyone for their dedication and hard work, and thank everyone for their contributions to this project. Final Report 8 Blue Wing Services

9 3 Methodology and Approach An objective analysis was conducted to identify the best overall radio systems solution for the Knox County Emergency Communications District (KCECD). This analysis is focused on determining if the negotiated contract with Harris Corporation or the Motorola-provided TVRCS approach best meets the needs as outlined in Request for Proposal (RFP) 1914, Wide Area Radio System. Blue Wing has developed and applied a methodology that aligns with the County s guidelines. Our approach is divided into three segments, they are: Comparative Analysis Data Collection Review of Collected Data Comparative Matrix and Reporting 3.1 Comparative Analysis Data Collection It is vitally important to KCECD that all aspects of this transitional decision be considered for analysis. Close consideration was given to aspects of, governance, ownership, subscriber functionality and participation costs, and overall economic feasibility. With this in mind, Blue Wing collected and compiled a large volume of data for review and analysis. Documentation and information that was collected include the following:: TVRCS radio system documentation for a comprehensive understanding of existing radios systems, portable/mobile//termination consoles and their respective lifecycle status and capabilities. Including, radio system documentation relevant to system attributes including coverage/propagation data, capacity, network features and reliability. All documentation related to the objective analysis; including the Motorola TVRS submittal, Harris countywide radio system proposal, RFP Wide Area Radio System, and other proposal submissions relevant to the analysis. In addition, information was obtained related to infrastructure equipment ownership, financial participation of county/agencies, equipment maintenance contracts and cost analysis. Collective dialogue via teleconference meetings and in-person stakeholder interviews with Knox County personnel, State and Local public safety end users, agency managers, and radio network user population. Review of local and cross-jurisdictional interoperability (City, County, and State). Final Report 9 Blue Wing Services

10 Review of current training, emergency exercises and state-led initiatives that may impact radio system transitioning. 3.2 Review of Collected Data Data was collected via teleconference meetings and in-person stakeholder interviews and has been compiled into summary reports and meeting minutes. The interviews were composed of constituent questions specific to the individual position and responsibility. Summaries were drafted from stakeholder responses that were used when comparing the various radio system options. Data collection also took place to establish and confirm the County s radio system requirements. These requirements were best captured in RFP 1914, Wide Area Radio system. From this RFP, a matrix was developed to present each requirement, along with information regarding each radio system option. This methodology enables KCECD to consider its final decision based on familiar criteria previously deemed vital to current and future Public Safety requirements. 3.3 Comparative Matrix and Reporting Blue Wing interpreted and analyzed the collected data, developing a matrix that presents and prioritizes the findings to identify any potential advantages and disadvantages associated with the Harris Contract and/or use of the TVRCS. Our Comparative Matrix addresses five (5) categories that are considered key to providing a comprehensive analysis. An outline of our Comparative Matrix is provided below: Technical o Coverage o Capacity o Spectrum o Design o Functionality o Interconnectivity o Dispatch Operations o Data Governance o o Interoperability o Testing & Validation Final Report 10 Blue Wing Services

11 o Maintenance o Integration Services Growth and Enhancements o System Expansion o Technology Refresh o Technology Obsolescence Cost o Initial o Recurring o Cost Analysis and Comparison o Subscriber Radio Costs Timeline o Implementation Timeline The comparative matrix was then incorporated into this final report and presented on a section by section basis. The tables included in this report are direct exports from the comparative matrix and present the requirement, as well as compliance and information for a Harris county-owned radio system and TVRCS radio system options. Final Report 11 Blue Wing Services

12 4 Comparative Analysis - Technical This section includes information related to the technical aspects of each radio system option for Knox County. Knox County RFP 1914 was used as a baseline for the County s technical system requirements. 4.1 Coverage This section presents the requirements for radio coverage in and around Knox County. The coverage requirements for the new radio system were included in RFP 1914, and are summarized as follows: 95% countywide radio coverage using a portable, on the hip, for talk out (system to radio) coverage, and at head level for talk back (radio to system) coverage. In-building coverage will be characterized, but not established as a coverage requirement. Audio quality for radio transmissions is measured at a delivered audio quality (DAQ) of 3.4. The definition of DAQ signal quality measurements is provided in the following table (DAQ 3.4 highlighted in green). Level DAQ 1: DAQ 2: DAQ 3: DAQ 3.4: DAQ 4: DAQ 4.5: DAQ 5: Definition Unusable. Speech present but not understandable. Speech understandable with considerable effort. Requires frequent repetition due to noise or distortion. Speech understandable with slight effort. Requires occasional repetition due to noise or distortion. Speech understandable without repetition. Some noise or distortion present. Speech easily understandable. Little noise or distortion. Speech easily understandable. Rare noise or distortion. Perfect. No distortion or noise discernible Table 4-1: Delivered Audio Quality (DAQ) Definitions Final Report 12 Blue Wing Services

13 Comments and observations related to this section s requirements are provided below: The proposed radio system coverage for each system option is relatively similar, from the perspective of percentage of area covered. This similarity is mainly due to the County s approach of defining sites and frequencies in its Request for Proposal (RFP). Blue Wing believes this is a wise choice and allows for a better analysis of vendor system offerings. Motorola has stated, in their revised proposal, that the proposed coverage is 97% countywide. This seems to be optimistic, but coverage acceptance testing will validate what the actual coverage turns out to be. The Fire community stated that they tend to operate on system during fire ground operations. If this is the case, the coverage was only specified as outdoor portable coverage, which could be a problem if Fire continues to utilize the system for fire ground communications. Fire should explore the use of conventional talkaround frequencies for fire ground, or vehicular repeaters to enhance in-building coverage. 2.1 General 2.1 General 2.1 General 2.2 Radio Coverage Requirements 2.2 Radio Coverage Requirements If multiple wide area controllers are necessary to provide the required network coverage, they must be capable of being linked for extended system wide communications. The network communications architecture will provide the radio user transparent radio communications across the entire area of coverage. The proposed P25 trunked radio system will permit the radio user to roam across the entire area of coverage without requiring manual switching or changing of site information. Proposer will be responsible for demonstrating mobile and portable radio coverage performance in accordance with the test plan defined later in these specifications. Coverage test should consist of talkout/talk-back audio quality evaluation within the coverage area that must meet or exceed the DAQ-3.4 audio quality requirement. not applicable.

Final Report 13 Blue Wing Services

14 2.2.1 Coverage Predictions Coverage Predictions Coverage Predictions Voice Quality Voice Quality Radio system coverage will be predicted through use of a radio wave propagation model that has been developed on the basis of theoretical and empirical data, which will take into account terrain irregularity, foliage, urban clutter, noise and long and short term signal variations. The model used for the purposes of the coverage prediction will be identified, and the rationale for system losses (e.g., power, gain, and loss information used in the model for each site) will be described in the Proposer's proposal. Single site and multisite composite coverage plots will be presented on an appropriate scale. If simulcast cells are proposed, then the maps must reflect noncoverage due to simulcast interference effects. Coverage is defined as the minimum signal required to provide a Delivered Audio Quality 3.4 (DAQ 3.4) voice quality, defined as "Speech understandable with slight effort. Occasional repetition required due to noise/distortion". Proposer shall relate this voice quality to a signal level for acceptance testing purposes..

15 2.2.3 Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement Portable Outdoors Coverage Requirement In Building Coverage Portable voice coverage within Knox County will be divided into a grid pattern of one square mile. The reliability within each square tile will be 95% of the service area with 95% reliability. The boundary of the portable outdoor service area shall be clearly indicated on the Proposer's coverage maps provided with their proposal and the estimated percentage coverage within this area also shown to validate that the predicted coverage meets the 95% requirement. Proposer shall include coverage maps in their response when operating in clear or encrypted mode for portable talk out and talk back coverage within Knox County and an area extending five (5) miles outside of Knox County as stated in Sec of the TN State Plan Region 39. Proposer will provide all parameters and assumptions used to generate the coverage maps. Portable Radio-Receiving: Shall be based on the use of a 1/2 wave whip portable antenna worn at hip level, three (3) feet above ground at 95% within the borders of Knox County. Portable Radio-Transmitting: Shall be based on the use of a V2 wave whip portable antenna at the users head level, five (5) feet above ground level at 95% Area Reliability. Proposer will provide detailed RF propagation coverage prediction analysis for the limiting case of talk-out or talk-back for portables outdoors. Proposer shall provide a statement of talkout to talk-back system balance. All Mobiles radios will also meet or exceed these requirements. Also, Proposer shall submit detail pricing for Portable Outdoor Coverage to meet 97% coverage requirement using same requirements as 95% coverage. As part of the initial system design and proposal response, the Proposer shall conduct a predictive analysis of the Knoxville Police Dept. Building and City County Building and a maximum of 13 other buildings to be decided at time of coverage test. Buildings are all of those facilities that require a 95% or higher percent of coverage reliability on the ground floor and all above ground floors. TVRCS with Motorola s 10/13/2015 revised submittal Additional coverage maps were provided in Motorola s 10/13/2015 revised submittal. Some additional detail was provided in Motorola s 10/13/2015 revised submittal. with Motorola s 10/13/2015 revised submittal Motorola provided additional coverage maps, but did not definitively state that the proposed system was balanced for portable outdoor coverage. Motorola has stated that the current design already provides 97% countywide coverage. with Motorola s 10/13/2015 revised submittal Final Report 15 Blue Wing Services

16 2.2.5 Mobile Radio Coverage Mobile Radio Coverage 3.1 Wide Area Communications Mobile radio coverage shall be based on the use of a 1/4 wave vehicular antenna, center mounted on the vehicle roof, five feet above ground level, both stationary and moving, at up to eighty (80) mph at 95% within the jurisdictional, limits of Knox County. Proposer shall include coverage maps in their response when operating in clear or encrypted mode for mobile talk out and talk back coverage within Knox County and an area extending five (5) miles outside of Knox County as stated in Sec of the TN State Plan Region 39. The system shall provide the ability to place and receive calls to and from any point in the network covered by the P25 800MHz trunked simulcast radio sites. TVRCS with Motorola s 10/13/2015 revised submittal with Motorola s 10/13/2015 revised submittal 4.2 Capacity This section provides requirement for radio system capacity. Capacity is the ability for the radio system to accommodate a quantity of radios and talkgroups in both day-to-day operations as well as times of emergency. Comments and observations related to this section s requirements are provided below: Capacity was established by KCECD in the radio system RFP The County required the use of twenty 800 MHz frequencies that are already licensed. Using less than all twenty channels will result in the County losing frequencies that are not built out and in service. Knox County required a migration path to P25, phase 2 technology, essentially doubling the number of talkpaths for the same amount of radio spectrum. Both vendors are compliant with the use of twenty (20) 800 MHz frequencies and with the migration to P25 phase 2. Twenty (20) channels of P25, Phase 1 equates to nineteen (19) talkpaths (one channel is always used as a control channel), and a migration to P25 Phase 2 provides thirty-eight (38) talkpaths. This capacity is more than sufficient for the County. Final Report 16 Blue Wing Services

17 1.2 Current Operations Simulcast Locations Voice, Data and Control 4.1 System Performance Requirements - Voice 4.1 System Performance Requirements - Voice Knox County Emergency Communication District currently operates a 5 site 20 channel Analog system with a single site 5 channel backup system. Simulcast is required for spectral efficiency or capacity requirements. The system shall provide a minimum of one voice call per 12.5 khz of radio channel spectrum, with a migration path to one voice call per 6.25 khz. The system shall support a fleet of approximately 5900 voice users with a potential 30% growth. The system shall support a minimum of 19 concurrent voice calls based on today's current system.. Linear simulcast has been proposed. TVRCS. Linear simulcast has been proposed. Not provided. However, capacity should not be an issue. 4.3 Spectrum The spectrum requirement refers to the band of frequencies to be used on the radio system. The radio system frequencies for use will be in the 800 MHz band. Comments and observations related to this section s requirements are provided below: Only 800 MHz spectrum was to be used for the system design. Knox County is currently licensed under the following call signs: o WNFF582 o WPQD207 o WQDN683 The FCC licenses will need to be modified once the County migrates to P25. No other issues were noted with the frequencies or FCC licenses. Both vendors are compliant with the requirement to only utilize 800 MHz. TVRCS 2.1 General The P25 trunked radio system shall operate in 800MHz Frequency Range. Final Report 17 Blue Wing Services

18 TVRCS Radio Frequencies Only existing licensed frequencies shall be used for this system. No new frequencies or additional channels will be considered in this project. Proposer will be responsible for all licensing, registration and frequency coordination of frequencies used Radio Frequencies Proposer shall supply frequency analysis and intermodulation analysis. Not provided. 4.4 Design Mandatory and optional system design parameters were presented in Knox County s RFP. This section details the design parameters, vendor compliance, and whether or not each parameter was mandatory or optional. Comments and observations related to this section s requirements are provided below: TVRCS does not currently have a redundant master core. In the event of a master core failure, or a failure of connectivity to the master core, the Knox County simulcast zone would still operate, but 911 Dispatch would need to revert to control stations for communication with Emergency Responders. Blue Wing asked Harris to expand on the ability to synchronize Netclocks, ensuring the timing of public safety systems is the same. Harris explanation is provided below: o Harris provides NetClock product per server core to provide time synchronization of the operating systems to support logging events, records management, network optimization and troubleshooting. For Knox County, Harris is providing two NetClocks, one for each server core (Primary and Secondary) as they are geo-separated and each require a time synchronization to support redundancy. The NetClock product primarily provides NTP (Network Time Protocol) service which servers and other network devices will subscribe to the NTP broadcast. Once a device has subscribed to NTP service (from NetClock in this case) the device will receive a UDP timestamp datagram on a specific UDP port (123 normally) that will cause the computer or network device to update their clock. In the case of having multiple NTP servers on network there are two approaches. First on a larger network the NTP servers such as NetClock could all synchronize to UTC time Final Report 18 Blue Wing Services

19 (Coordinated Universal Time) through a GPS antenna (Stratum 0 time source) and since all NetClocks are talking to the same source there should be a very small tolerance of time delta based on local network latency (a few milliseconds). The second approach would be to have one of the NetClock become a local master time source (Stratum 2) and the other NetClocks could use the master as the time source instead of the GPS signal. Note, when the GPS signal is not available the Netclock product has an internal clock that will maintain time source. Motorola also provided additional input regarding the use and synchronization of the Netclock. Motorola is proposing that Knox County use its own Netclock to provide timing to the console system. The Knox County Netclock and the TVRCS Netclock would be synchronized by the universal GPS satellite system, which would provide synchronized timing down to a few microseconds. The Harris county-owned system offering supports both Fire Alerting and Knox Box activation on the P25 system. The Motorola TVRCS option would require an analog simulcast overlay for the Fire Alerting system. Motorola stated that the current Fire Station Alerting MOSCAD will not work on a digital P25 radio system, hence the reason for a conventional simulcast overlay. The Knox County Fire Community has released an RFP for a new fire alerting system, so the analog simulcast overlay will not be required after the fire alerting system is replaced. Knox Box functionality is only supported by APX radios. Therefore, the Fire Community will need to purchase new radios, upgrading existing XTS/XTL radios to P25 is not an option. TVRCS does not currently have an ISSI for inter-system interfacing. For a Harris county-owned radio system, the ISSI would need to be purchased for the County system and TVRCS. for the radio system, and the subscriber radio fleet is included with the Harris proposal. However, the TVRCS option would require Knox County to negotiate system management functionality and sign an Although the details of the system management functionality are not yet known, it has the potential to be more limiting with the TVRCS option.

20 TVRCS 1.1 Overview Knox County Emergency Communication District intends to purchase a five (5) site 20 channel P25 IP based 800MHz simulcast digital trunked radio system infrastructure with applicable APCO project 25 protocol this is to include replacement of 17 Gold Elite Dispatch Consoles. 1.1 Overview 1.1 Overview 1.1 Overview 1.2 Current Operations The requirement is for the system to be usable throughout the Knox County E911 coverage area, and using 800 MHz radio channels. The system should be a highly reliable, fault tolerant system which will meet current needs and provide a growth path for future expansion. In particular, the system must be FCC compliant with the P25 Phase 1 protocols and provide a clear migration path with a commitment from the Proposer to be compliant with the P25 Phase 2 requirements. Knox County Emergency, Communication District has a minimum of 5900 users on the system and intends to add additional users beyond the initial identified requirements, and requires that this system allow for a potential 30% future growth of the system. Knox County Emergency Communication is requesting proposals for a five (5) site 20 channel P25 IP based 800MHz simulcast digital radio communications system with wide area communication capabilities for all users throughout the operational area of Knox County Emergency Communication District.. Redundant prime site controller was proposed as an option, it has been calculated into the overall pricing on the Costs sheet. 2.1 General The backbone of the system shall consist of multiple repeater sites connected to a wide area controller, or switch, to provide reliable wide area voice and data communications to and from mobile and portable units throughout the desired area of coverage.. Although the TVRCS option does not provide for a Countyowned master site. 2.1 General Consistent with the goals of P25, Proposers will demonstrate multi-proposer interoperability both through support of P25 Trunked Common Air Interfaces (CAI) and the P25 Inter-Subsystem Interface (ISSI). The Proposer will also include a list of installed systems of capabilities set forth in this RFP.. ISSI functionality is available but the license must be purchased.

27 3.3.1 Basic P25 Trunked Operation Call Queuing Voice Group Priority Voice Group Priority Voice Group Priority Group Busy Lockout Group Busy Lockout The system shall support P25-defined "announcement group calls" (allowing a dispatcher or authorized user to communicate to a number of individual groups) and "all calls" (allowing a dispatcher or authorized user to communicate to all users on the network. If resources are not immediately available for a call originating from the network side, the system shall queue the channel request to the base station until the radio channel is available. The base station shall queue calls originating from the network side based on voice group priority, with a minimum of eight priority levels. Calls will be positioned in the queue based on priority, with calls of highest priority (such as emergency calls) being serviced first. Calls of equal priority shall be processed on a first in, first out basis. This feature prevents other voice group members from interrupting a user who is actively transmitting on a voice group. If a member of a currently active voice group presses PTT to initiate a call on the same voice group, the system shall refuse to repeat the call. This is independent of the "Busy Channel Lockout" capability of the subscriber unit.
