1

Executive Summary■ Existing systems at end of life and UHF-T Spectrum set to be vacated by

Public Safety users in 2023

– Based on analysis, V-COMM recommends pursuing 700 MHz

Spectrum

■ V-COMM proposes the implementation of a state-of-the-art P25 Phase 2

County-wide Trunked Communications System

– Conceptual System will consist of 24 Transmit/Receive sites

throughout Delaware County

■ In the short-term, the County requires a back-up UHF solution to overcome

shortcomings of existing UHF-T systems

■ Conceptual System will require significant infrastructure upgrades to protect

new radio equipment investment

2

Executive Summary■ Conceptual System will require investment into new subscriber units for

portable and mobile use

– V-COMM recommends a user agency survey to confirm exact

subscriber unit quantities and types

■ Conceptual System will utilize existing microwave ring, as well as two

additional microwave rings, to backhaul all capable sites and minimize single

points of failure

■ Conceptual System will utilize existing dispatch equipment, as the County has

recently invested in dispatch upgrades

– V-COMM recommends the acquisition of new Dispatch furniture, as the

existing furniture is worn-out

■ The all-in budget for the conceptual system is estimated between $51.7M

and $69.9M

3

Recommendations Summary■ Pursue 700 MHz spectrum

■ Deploy a 24 site design to provide acceptable County-wide portable coverage

■ Invest in site infrastructure (towers, compounds, shelters, etc.) to support 24

site design and secure radio investment, including two core site locations

■ Execute a thorough user agency survey to confirm exact subscriber unit

quantities and types

■ Reuse existing microwave ring to leverage previous County investment

■ Supplement existing microwave ring with two additional rings, and add four

spurs to backhaul 23 RF sites

■ Replace existing dispatch furniture that is worn-out

4

Recommendations Summary■ Upgrade Zetron dispatch system to support P25

■ Deploy a network management system to monitor and protect future County

investment

■ Develop solutions with nearby agencies to provide interoperable

communications between agencies to leverage County investment

■ Short-Term Recommendations

– Analyze Channel availability in UHF

– Develop “system” design to utilize new channels

– Leverage existing system architecture

– Baseline existing system for moving forward

■ Verify existing subscriber equipment is operating correctly and to

specification

■ Verify all satellite receive sites are operating correctly and to specification

5

Short-Term■ County will exist on UHF-T Spectrum until new system can be deployed,

tested, and users cut-over

■ UHF-T Spectrum DTV interference will not go away (can potentially get worse)

■ County requires Short-Term Back-up solution

– UHF Channels only option that does not involve extreme cost burden to

user equipment

– UHF Spectrum Highly Congested

■ Potential to identify a few channels

■ Unlikely to be licensable county-wide

6

Existing System Spectrum Assessment

7

Existing Delaware County System■ Existing Delaware County System(s) operate on UHF-T Spectrum

– Existing system is over 20 years old and has reached its end-of-life

– Per the Middle Class Tax Relief and Jobs Creation Act of 2012, the

UHF-T spectrum is set to be vacated by 2023.

– In addition, the UHF-T band is hampered by interference from Digital

Television (DTV) Ducting, which can cause entire channels to be

unusable system wide

■ Delaware County Police Department utilizes 7 Primary and 7 Secondary

UHF-T channels to cover 7 Sectors within the County

■ Delaware County Fire Department utilizes 7 Primary, 4 Simplex , 3 Secondary

UHF-T Channels for 6 FD Zones within the County, with 2 Channels dedicated

for EMS

UHF-T Spectrum Analysis■ Middle Class Tax Relief and Job Creation Act of 2012 is still the “Law of the

Land”

■ The FCC shall issue procedures to Auction off the T-Band “Public Safety”

Spectrum by February 2021

■ Within two years of the completion of the auction , Public Safety Agencies

must vacate T-Band

■ Only an Act of Congress can change the Law. The FCC has no say in this

area.

■ Large Users (LAPD, NYPD and Chicago PD) are pushing hard for repeal or

delay of the Law

39

UHF-T Spectrum Analysis■ In January, a Bill to repeal the T-Band Act was introduced in the US House;

H.R. 451. There are 18 co-sponsors, however it is still in Committee.

■ On Oct. 31, 2019, a companion bill was introduced in the US Senate

■ The FCC has frozen T-Band, no License renewals are being granted, renewal

requests will go into “pending status” permanently.

■ Once in this state, no license modifications can be made, even simple

emission designator changes.

40

UHF-T Band – The ACT■ The Middle Class Tax Relief and Job Creation Act of 2012 (Public Law 112-

96; “The Act”) requires the FCC to auction the T-Band spectrum assigned to

public safety users. Proceeds from this auction will then be used to relocate

the existing (incumbent) public safety users elsewhere.

■ “SEC. 6103. 470-512 MHZ PUBLIC SAFETY SPECTRUM. (a) In General- Not

later than 9 years after the date of enactment of this title, the Commission

shall-- (1) reallocate the spectrum in the 470-512 MHz band (referred to in

this section as the `T-Band spectrum') currently used by public safety

eligibles as identified in section 90.303 of title 47, Code of Federal

Regulations; and (2) begin a system of competitive bidding under section

309(j) of the Communications Act of 1934 (47 U.S.C. 309(j)) to grant new

initial licenses for the use of the spectrum described in paragraph (1). (b)

Auction Proceeds- Proceeds (including deposits and upfront payments from

successful bidders) from the competitive bidding system described in

subsection (a)(2) shall be available to the Assistant Secretary to make grants

in such sums as necessary to cover relocation costs for the relocation of

public safety entities from the T-Band spectrum. (c) Relocation- Relocation

shall be completed not later than 2 years after the date on which the system

of competitive bidding described in subsection (a)(2) is completed.”

41

700 MHz Spectrum Analysis■ V-COMM recommended solution for Delaware County

■ Nine (9) channel pairs with 25 kHz Bandwidth are allocated to Delaware

County by Region 28

■ Channels acquired via formal, defined Region 28 Application process

– No applications against these channels have yet been submitted

– Requires justification of need

– Requires design that meets Region guidelines for interference and

Responsible Radiation

– Frequency Coordination among Spectrum Coordinators (e.g. APCO)

– P25 System licenses - 12.5 KHz pairs

800 MHz Spectrum Analysis■ Unlikely To Find Enough Channels for a sole 800 MHz solution for Delaware

County; however 800 MHz spectrum can be used in conjunction with 700

MHz spectrum on the same system to increase capacity

■ NPSPAC Spectrum (851-854 MHz)

– Channels acquired via formal, defined Region 28 Application process

– Requires design that meets Region guidelines for interference

– Frequency Coordination among Spectrum coordinators (e.g. APCO)

■ 800 MHz General Spectrum (854-860 MHz)

– Channels acquired via Frequency Coordination among Spectrum

coordinators (e.g. APCO)

– Requires design that meets FCC guidelines for interference

– Must meet power and Antenna height requirements set by FCC

44

Current County Radio Usage Analysis■ County provided V-COMM with Radio Usage (Call Counts by Channel) for eight

(8) months in 2019

■ Current Maximum “Busy Hour” Channel use : 16 Resources

Radio Capacity Overview■ System level overview affecting traffic of conceptual system design:

– Trunked Technology

■ “Control Channel”

– Frequency channel radio contacts network on to receive traffic

channel

■ “Traffic Channel”

– Frequency channel on which modulated voice signals are

transmitted on

■ All Traffic Channels are shared across network

■ Each voice transmission carries a data tag corresponding to the talk group

the call was made on

■ Only Radios included in the same talk group will playback the repeated

voice transmission

46

P25 Phase 2 TDMA Overview■ System level overview affecting traffic (cont’d):

– Time Division Multiple Access (TDMA)

■ Each channel is 12.5 kHz wide

■ Each channel will be split into interleaving timeslots

■ (2) Voice transmissions will be split into small sections and interleaved into

one contiguous

■ Results in 2 talk paths per 12.5 kHz channel

Existing Network Deficiencies■ Frequent sporadic coverage issues due to:

– DTV Ducting in 500 MHz spectrum

– High number of satellite receive-only sites

– System infrastructure and subscriber equipment at end-of-life

– Poor backhaul reliability, outages

71

Conceptual RF System Design

72

■ Proposed P25 Phase II 700 MHz Digital Communications System

– Will combine all County operations onto single system, including PD, FD, and EMS

■ System designed for 97% reliable, Delivered Audio Quality (DAQ) 3.4 coverage throughout Delaware County, including in-building coverage

■ Conceptual design consists of 24 Tx/Rx sites

– Leverages mainly existing TX/RX and Rx only sites

– Leverages eight (8) existing sites at which Delaware County does not currently have infrastructure

– Conceptual design utilizes only existing infrastructure (i.e. no new tower builds) and assumes collocation availability

Area Coverage Reliability and DAQ are functions of radio service to determine optimum Channel Performance Criterion ( CPC)

– 97% Area Coverage Reliability is the probability that the measured coverage within 97% of the service area is greater than or equal to predicted signal strength

– Service Area will be tested as a uniform test grid of 1/2 mile by 1/2 mile test tiles (1/4 mile square) that covers the entire COUNTY geographic area

– In each test tile, RSSI and BER measurements shall be taken. The mean BER value of all collected data points shall be 2.4% or better, median RSSI value shall be equal to or greater than the faded signal strength required to achieve the CPC.

– DAQ 3.4 is comparable to 20 dB SINAD equivalent intelligibility, i.e. Speech understandable with repetition only rarely required. Some Noise/Distortion

Building Penetration Losses■ TSB-88 defines a generalized median in-building penetration loss across all

building types

– 700 MHz median value = 14.5 dB

– 700 MHz standard deviation = 7.8 dB

– Most buildings exist between 6.7 and 22.3 dB (1 standard deviation)

– In order to better quantify in-building attenuation, V-COMM breaks

down the in-building penetration levels into 2 categories

■ Higher attenuation “Commercial / Industrial” type buildings

■ Lower attenuation “Residential” type buildings

80

Building Penetration Losses■ Commercial and Industrial Type Building

– Assumed margin of >20 dB above on-street predicted levels

– Building types

■ Hospitals, factories, malls, schools, large department stores (e.g. Home

Depot, Walmart), large apartment complexes, older, heavy concrete

facilities (e.g. courthouses, municipal buildings), large office complexes

■ Residential Type Building

– Assumed margin of >10 dB above on-street predicted levels

– Building types

■ Residential houses, wood frame structures, small apartment complexes,

smaller commercial buildings (e.g. restaurants, local businesses, small

office buildings), fire and police stations

81

Existing Site Survey Assessment

82

Site Survey Overview

■ Included visits to sites with existing UHF County equipment

■ Did not include sites that were not considered feasible for a P25 Tx/Rx site

on the new system

■ Survey focused on general site conditions including the “tower”, shelter, and

compound area(s).

■ A matrix was developed to document the conditions and suitability of the site

for future use

■ The matrix is used during the budget phase to develop a per site budget

estimate to improve the site conditions to support the new P25 System

including proposed microwave backhaul

– Springfield#1 and #2– Site #1 is American Tower asset. Unable to

access shelter. Site #2 is also American tower asset. Shelter is very

small but could support more equipment. Shelter is not behind a fence

and does not have proper cable routing to tower. Grounding, proper ice

bridge, compound fencing are needed and a larger shelter if

recommended. Tower has height and ATC records show room. ATC

database does not show Delco as a tenant

– Lima #1 & #2 – New shelter to be placed on site. Tower has good

height and location. Structural analysis for this tower shows it is failing.

No documentation provided to show that it has been fixed or off

loaded

86


■ Day 2

– Prison –T-Mobile built new Tower and would own for first 5 years from

what we were told. Need to get ownership changed if this is case on

ASR. Shelter on site clean but needs some external repairs on facial

due to storm damage. Grounding on door needs to be repaired and

grounding should be checked. Last structural shows tower at 100% or

105% capacity. Old ASR on fence, needs to be removed and FCC

notified it has been decommissioned

– Bethel – American Tower and shelter Assets. Shelter clean and

grounding intact. ATC database does not show Delco as a tenant and

limited space on tower

– Aston Tower – SBA asset. Shelter clean and has space. Site will need a

generator. Guyed Tower has AM protection on lower 2/3s of tower

87


■ Day 2

– Eddystone – Site clean and has space to grow. Grounding looks to be

intact. Old cabling and equipment on tower should be removed before

tower assessment. ATC database shows space available.

– Chestnut Ridge – Tall building in good location and view of surrounding

area. Roof very busy but has space. Space on upper floor for

equipment area. Current equipment is out in open. If site chosen will

need to get a fenced/secure area.

– Scott Paper/International Plaza – Equipment in open unconditioned

area. Site has good height and close to airport. This site would need

better space for equipment.

– Darby Tower – Shared shelter space with Verizon. Very limited space

and very low monopole. Do not recommend keeping this site.

88


■ Day 3

– Haverford Township Admin – County equipment located in basement

(building maintenance room) and not conditioned. Building has been

sold and County looking to add shelter outside in American tower

compound. Monopole is very full

– Marple #1 & #2 – Marple Tower #1 is in Crown Castle database. Crown

Castle says they no longer manage this tower and did not have any

record of County on tower. Shelter A/C in very poor condition and

grounding has been cut away and requires repair. Higher fencing and

barbed wire/camera network recommended. Marple #2 has height,

but tower failed Structural analysis and can not be used. Site shelter

grounding in serious need of repair and has been cut away outside of

building

89


■ Day 3

– Radnor #1 – Good location and height to building. Equipment room is

full and not conditioned. No room to expand. Roof top very full,

additional antenna co-location doubtful. Existing landlord relationship

poor(no access to roof at time of visit)

– Radnor Remote – Delco using PECO power tower and has cabinet on

ground. Plenty of space on ground for more cabinets. Current antenna

is below power lines

– Radnor #2 – Sharing shelter space with Radnor police. One small air

conditioner for 10x10 room. No space to grow. Recommend installing

new shelter on Radnor police grounds if possible with generator

– HVD State – Site appears to have been abandoned at one time, all

grounding was cut out and door is rusting away. Site needs grounding

repaired and checked. Top of tower looks available. Site needs

generator and shelter repairs

Existing Backhaul Assessment

106

Backhaul Assessment■ Backhaul is all the components and paths to carry radio (and other) traffic

from the “tower” sites (transmit, transmit/receive, and receive sites) to the

central communications center at Lima

■ Currently System Utilizes

– Licensed Microwave

– Leased “Copper”

■ T1

■ RTNA

■ Non-Conditioned 4W

107

Licensed Microwave Assessment■ Provides most reliable interconnect

■ Allows for County control of asset

■ Must be designed to ensure proper “five 9’s” reliability (99.999 is less than

5.26 minutes of outage per year)

■ Adds weight and lease cost (typ) on rented towers

■ Upfront CAPEX cost, relative small OPEX cost

■ Potential for carrying other County traffic

■ Current Architecture

– Has evolved overtime to improve design/performance

– All planned (and licensed) improvements have not been completed

Architecture All Links – Summary■ System has a lot of backhaul methods

■ System has many potential points of failure

■ County is paying large sums (OPEX) for “copper” backhaul

■ New System should look to migrate to Microwave as much as possible

■ New system will not require the number of interconnections as current system

■ If microwave interconnect not possible, County Fiber or other third-party Fiber should

be considered

– County Fiber

■ Limited availability (geographically) for sites

■ Exact locations TBD

– Could be provided via third party

■ Higher OPEX vs. County-owned fiber

■ Similar or lower OPEX vs. existing copper backhaul

■ Minimum bandwidth costs far exceed need

■ May not be available at all site locations

Conceptual Backhaul Architecture

122

Design Approach■ Maximize Microwave Interconnect

– Provides most reliable interconnect

– Allows for County control of asset

– Minimizes single points of failure

■ Eliminate as much as possible existing leased “copper” circuits

– Expensive OPEX

– Unreliable

– Large potential savings >>$350K-$400K+/year

123

Microwave Design Assumptions■ Links greater than 6 miles or greater than maximum tower height removed

■ Assumed all 11 GHz paths

■ Assumed 100’ clearance criteria to terrain

■ Assumes Lima as core location

■ Link antenna heights represent minimum requirements for 100’ clearance

– Does not represent actual location availability on tower

– Does not include real-world obstruction, reflection, or path reliability

analyses

Existing Dispatch Assessment■ Eventide Logger (Cabling)

■ Zetron Acom Dispatch System

■ Vesta 911

■ CAD System

■ Dispatch Furniture

■ Incoming Building Electrical

■ Core Equipment Room- HVAC , Flooring , Room Space

■ UPS – Battery Backup

137

Existing Dispatch Assessment■ Adequate

– Newly Updated Vesta - Text to 911 by end of 2019

– Eventide logger

■ All relatively new CAT5/6 cabling ; 3 years old/redundant

■ Requires expansion to support integration with new P25 radio network

– Zetron Acom Dispatch System– upgradable to support integration with

new P25 radio system

– Video feeds from Penn DOT, Housing projects come into

Communications Center

– Separate phone system for PSAP interaction

– UPS at each dispatch station

138

Existing Dispatch Assessment■ Unsatisfactory

– Worn furniture

– Electrical Maxed Out in the Dispatch but satisfactory for current

configuration

– Equipment Room

■ Current equipment room crowded and requires multiple HVAC units

■ New room (IT room) identified for the new P25 System Equipment

installation

139

Conceptual Dispatch Analysis

140

Conceptual Dispatch Analysis■ Dispatch Room Recommendations

– Update furniture/flooring– ensure upgrade is rated for 24/7

continuous usage

– Zetron Upgrade to support P25, Traffic Growth

■ Equipment Room Recommendations

– Install new 700 MHz System Equipment in IT room which to beconverted to new Equipment Room

■ Includes HVAC, UPS, Flooring Upgrade, Fire Suppression

■ Alleviate space issues within main equipment room.

■ Additional space allows for optimal layout of equipment

■ No disruption to current dispatch during construction

– If IT Room cannot be achieved:

■ Existing equipment reconfiguration to optimize floor space to install newP25 system equipment

■ HVAC fix in existing equipment room

141

Alarming and Interoperability

142

Alarming Summary■ Delaware County has no existing NMS system for its radio network and

infrastructure

■ Every radio vendor will have an in-house NMS system that will monitor that

vendor’s radio and networking equipment

■ Large systems typically also use environmental alarms to monitor site

conditions

– Intrusion/Door Sensors

– Temperature/Smoke/Fire/Hydrogen Sensors

– DC power plant and main power sensors

– Water Sensors

■ The radio vendor NMS will be capable of monitoring environmental alarms as

well as third-party equipment (e.g. existing microwave network equipment)

that contains non-proprietary monitoring interfaces (e.g. SNMP or dry

contact)

143

Alarming Recommendations■ The County should deploy full system alarming to remotely monitor its

network.

■ Such monitoring includes

– Radio equipment status and configuration

– Network equipment status and configuration

– Site environmental status

– 3rd Party equipment status (configuration is possible)

144

Network Management Operations■ NMS access should be provisioned for persons in charge of managing any

portion of the radio network with appropriate access granted based on the

accessor’s role

– Most monitors would only need visibility, not configuration ability

– Remote access should be granted through the firewall so such persons

need not be connected within the radio network WAN

■ Alarming would be monitored by a dispatch supervisor 24/7 who would take

action based on alarms noticed

– Request patrol to check site status

– Request IT to troubleshoot down link

– Report to radio vendor equipment warnings

145

Interoperability■ V-COMM’s understanding is that all municipalities within Delaware County will

use its new P25 radio system, leaving no need for inter-County

■ Delaware County should negotiate with the states of Delaware and

Pennsylvania as well as surrounding PA counties for an ISSI link with their

P25 systems.

– PA: Chester, Montgomery, Philadelphia

– State of Delaware

– State of Pennsylvania

– State of New Jersey

– Delaware River Port Authority

– NJ: Gloucester

■ Recommend consoles patching for outside municipalities that do not

implement P25 or cannot afford an ISSI

146

Interoperability■ ISSI

– Most expensive interoperability option

– Most complete interoperability option

– Allows a user to automatically roam from their primary radio network to

an ISSI-connected radio network

– There must be a physical backhaul link between the connected

systems (e.g. leased line, microwave)

– Agencies using an ISSI link must carefully plan sharing of fleet

mapping to ensure functioning roaming

– Allows for automatic connectivity between talk groups of disparate

systems

147

Interoperability■ Console Patch

– Typically, least expensive interoperability option

– Provides minimal support for roaming users

– Requires manual intervention by a dispatcher

– There must be a physical interfaces between the radios, often a

control station with a yagi pointed towards the partnering agency

– Agencies must setup careful procedures for sharing of the patch to

prevent inadvertent use of a channel on a connected system

148

Budgetary Analysis

149

150

Budget

■ Pricing based on researched State Contract Pricing data

– State contract typically 20% off vendor list*

– Additional discounts MAY be offered over State

– User equipment pricing uses “blended” amounts from three primary vendors

■ System “inclusions” based on Delaware County discussions and V-COMM experience

■ Standard Warranty is included in the budget for Primary Radio Vendor Estimate

■ Standard Warranty terms are different for End user Equipment ( 3 years typical) and network infrastructure( 1 to 2 years typical)

■ The OPEX costs will vary from Vendor to Vendor

■ V-COMM recommends that County requires Primary vendors to include the OPEX for up to 20 years (5, 10 , 20 years) as optional pricing when specification is developed

Note – JVCKENWOOD base station infrastructure is currently not on PA state contract; however, JVCKENWOOD subscriber equipment is currently on PA state contract.

Conclusions

■ Based on the above analyses and assessments, V-COMM concludes that the current

County UHF-T system is insufficient for Public Safety communications

– The system contains too many single points-of-failure and suffers from

extended outage periods which prohibit effective communications

– The UHF-T spectrum is prone to DTV ducting interference, and is set to be

vacated by Public Safety users by 2023

– The inefficient system site configuration and geographic distribution results in

unnecessary expenses and unreliable communications

■ V-COMM recommends the pursuit and deployment of a state-of-the-art, 700 MHz, P25

Phase 2 Digital Communications System to consolidate County-wide public safety

communications, including investment into radio, site, and subscriber infrastructure

■ V-COMM recommends taking immediate short-term action to identify specific

equipment and infrastructure issues

■ V-COMM recommends identifying, licensing, and deploying a UHF-based backup

system for operations during UHF-T degradation events

160

Conclusions

■ V-COMM has conceptually designed a 24-site solution to provide reliable, in-building

portable communications throughout Delaware County

■ V-COMM has conceptually designed a multi-ring IP-based microwave backhaul

solution to aggregate radio traffic for the proposed 24-site solution

■ V-COMM recommends pursuing 11 700 MHz radio channels via the Region 28

application process

■ The all-in budget for the conceptual system is estimated between $51.7M and

$69.9M
