Saratoga County System Design Review

Mark Hoppe Andrew Maxymillian

Overall Objectives
  • 1 - Provide Reliable Effective Public Safety
    Communications for Saratoga County
  • Develop a System that would provide the
    foundation for Public Safety Communications for
    the next 20 plus years
  • Provide Reliable Coverage throughout Saratoga
    County
  • Enhanced Operations via Voice and Data
  • Enhance Interoperability with neighboring cities
    and counties, and state agencies
  • 2 Achieve the Public Safety Communications
    Goals with the least impact on the community
  • Environmental impact of sites
  • Share resources as with other groups to reduce
    overall costs

3
Current System
  • Departments Overview

4
Current System
  • Issues
  • Reliability and Repairability
  • Basic System Design dates back to the 1960s
  • Components
  • Fire late 1950s
  • EMS - 1970s
  • Sherriff/Police system 1960s
  • Systems have many older components and components
    no longer available
  • Issue will remain with unpredictable outcome and
    consequences
  • Operations
  • Voice
  • Coverage Issues
  • Data
  • No data in most operations, limited coverage and
    use
  • Paging
  • Voice only
  • No data
  • Reliability of receiving

5
Current System
  • Issues
  • Interference
  • VHF Low-Band
  • Interference due to propagation characteristics
    of the band generally ducting from distant
    areas
  • Unpredictable
  • Unavoidable Most parties are operating within
    FCC guidelines
  • Low-band equipment lifecycle is near end
  • Coverage
  • VHF Low-Band and High-Band
  • Southern part of the county - Clifton Park,
    Halfmoon, Waterford
  • Eastern areas along Hudson
  • APA Areas - South shore and Military Road
  • Corridor Between Saratoga Springs and South Glens
    falls

6
Current System
  • Issues
  • FCC Issues
  • Narrow banding
  • Narrowing channels from 25 kHz to 12.5 kHz for
    spectrum efficiency - double the number of
    channels, but narrowing the FCC allowable
    channel, currently Saratoga County is
    non-complaint with future requirements.
  • Manufacture and importation of any equipment on
    25 KHz channel will be not be permitted after
    December 31, 2010
  • Systems operating on 25 KHz channels will not be
    allowed after December 31, 2012, all system after
    this date must operate on 12.5 KHz channels

7
Current System
  • Issues
  • Inhibiting Enhancements
  • Voice Features
  • Enhanced console abilities
  • Direct Interoperability between agencies
  • Data
  • Computer Aided Dispatch (CAD) functions for
    dispatching does not have the RF pipe and
    end-user radios to use functions
  • Paging
  • CAD functions for paging has the RF pipe, but not
    the end-user equipment pagers - to use enhanced
    features
  • Overall
  • Many advanced functions that are becoming
    commonplace for public safety operations are not
    available until one has the RF delivery mechanism
    and end-user equipment

8
Evaluation Process
  • Requirements Review
  • Review and validate existing County licenses
  • Review frequencies to determine availability
    (VHF, 700, 800)
  • Review traffic and loading to determine channel
    requirements
  • Review Functional Requirements with County
    (multiple radios, connectivity, coverage, etc.)
  • Site Analysis
  • Develop understanding of APA requirements,
    tendencies
  • Review NYS - SWN design to determine if shared
    site placement achieved
  • Review existing sites and potential sites
  • Develop Candidate Site List
  • APA View Shed by Chazen
  • Propagation Analysis
  • Preliminary Propagation Review
  • Review NYS - SWN design to determine if shared
    site placement achieved
  • Send out propagation request to Motorola and
    MA/Com to confirm coverage
  • Propagation drive test to confirm coverage
  • Finalize Candidate Site List
  • Report Development
  • Draft Final Report that contains findings and
    recommendations

9
Review Requirements
  • Frequency Resources
  • VHF
  • Find at a minimum 3 pairs for VHF simulcast or 9
    pairs for preferred VHF multisite solution
  • Review frequency reuse, splinter frequencies or
    use of other non-County controlled VHF assets
  • 700 MHz
  • (16) 700 MHz 25 KHz Frequencies Available for Use
    in Saratoga County
  • Involvement in process will ensure maximum amount
    of frequency allocation
  • 800 MHz
  • (22) 800 MHz NPSPAC County Frequencies
  • Licensed currently to existing sites
  • Frequencies are available for licensing including
    Spruce Mountain
  • Rebanding
  • Frequencies will have to be rebanded in the
    future
  • Rebanding will not have significant impact on the
    use of the frequencies

10
Requirements Review
  • Traffic and Loading
  • Channel Requirements
  • Based on traffic characteristics, radio users,
    channel loading requirements, and earlier traffic
    analysis
  • Channel requirements
  • (3) Voice/Data channels in the APA region per
    Site
  • (8) to (12) Voice/Data channels in the non-APA
    region per Site
  • Number of Radios
  • APA Region -
  • (2) Two Radios - VHF High-band and 700/800 MHz
  • Hadley is dispatched from Warren County on VHF
    High-band
  • Edinburg/Day have significant weekly operations
    with Fulton on VHF High-band
  • NYS DEC operates on VHF High-band for lost person
    and fire operations
  • non-APA Region
  • (1) Radio - 700/800 MHz
  • Currently, there is cross band operations
    occurring, most or all could be eliminated via
    cross-banding thru console and migration of users
    to one common system

11
Review Requirements
  • Functional Requirements
  • Coverage
  • Most important element in communications systems
    is coverage
  • Use defacto standard and commonly applied measure
    of 95 coverage, 95 of the time
  • Non - APA
  • 700/800 Mobile Coverage - 95/95 of the Non-APA
    Area
  • APA Area
  • 700/800 Mobile Coverage - 95/95 of the most
    populated areas of the APA
  • VHF Mobile Coverage - 95/95 of the land area
    of the APA
  • Connectivity
  • Simulcast technology mandated the use of
    microwave
  • If Simulcast not a requirement, Microwave
    preferred because of reliability

12
Site Analysis
  • Develop understanding of APA requirements,
    tendencies
  • Met with APA at Ray Brook and in the field
  • Defined conditions
  • Refined and gave feedback on findings
  • Reviewed View Shed and loading criteria
  • Refined "Substantially Invisible"
  • Minimal access, road and power requirements
  • Minimize ridge line sites that are back light
  • Reduce height to minimum required
  • Minimize size of antennas - especially MW
  • Blend/camouflage if improves substantially
    invisible
  • Other Criteria
  • Land ownership
  • Review focused on county or city owned property
  • Focused on willing land owner
  • Developed or minimum access requirements
  • Review existing sites and potential sites
  • Reviewed SSI work and site identified
  • Existing tower sites

13
Findings
  • Sites
  • APA New Builds
  • Fraker (Original Design - New Build)
  • Lakeview (Original Design - New Build)
  • Conklingville Dam (Replaces Mt. Anthony - Willing
    Landowner)
  • Lake Luzerne (Replaces Mt. Anthony - Town
    Property)
  • APA Existing Sites
  • Spruce Mountain (Existing Site - Potential
    Upgrades)
  • Corinth High School (Existing Site - Antenna on
    building for MW)
  • Non-APA Sites
  • McGregor (Original Design - New Build)
  • Providence (Original Design - Existing Site -
    Upgrades)
  • Halfmoon (Original Design- Existing) or Bald
    Mountain (Alternative - Existing)
  • Saratoga Springs Area (Existing)
  • Stillwater (Existing ) or Willard (Alternative -
    Existing)

14
Findings
  • Coverage
  • New Design - Key Elements
  • Meets coverage Replace Mt. Anthony with two low
    lying sites Conklingville Dam and Lake Luzerne
  • Brings Spruce Mt. into design for coverage and
    redundancy
  • Allows a vendor neutral solution for any vendor
    - Motorola or MA/Com
  • Provides Microwave connectivity to sites
  • Places sites to provide better coverage in
    critical portable patrol areas

15
Next Steps
  • Coverage and Connectivity Field Tests
  • VHF and 800 MHz Coverage Tests to finalize Height
    of Antennas above trees
  • 960 Links Tests to Verify Path Loss
  • Frequency Issues
  • Refine 700 MHz availability
  • Complete research on additional VHF frequencies
  • Site Agreements
  • Finalize Site Agreements with land owners at Lake
    Luzerne, Conklingville Dam and Corinth High
    School
  • Site Approvals
  • Complete site documentation for new APA sites for
    various government applications
  • FCC
  • Complete NEPA and other required Federal approval
    for new towers
  • Local Approval
