Public Safety Radio System
Prior Lake City Council
October 17, 2005
800 MHz Regional Radio
· Initiated in June of 2002
System of interconnected radio equipment
that includes (computerized automated
control units, radio transmitters and
receivers, repeaters, antennas ( located on
towers and high buildings throughout the
metropolitan region), fiber optic lines and
operations consoles
800 MHz Regional Radio
· The system is designed to provide trunked digital
800 MHz radio coverage and interoperability for
public safety entities.
· The regional backbone is owned and operated by
the Minnesota Department of Transportation
· Local entities, such as Scott County, who join the
system develop, own, and operate their own
subsystems.
Current VHF System
Unique Channels
· Law (x 2)
· Fire (x 1)
Simple / Analog
Frequency Limited
· Capacity Limited
Range Limited
Lowest Cost
Radio
"101"
800 MHz System
Shared Channels
· Computer Managed
Digital Operation
Greater Efficiency
Wide Area Coverage
Higher Cost
Shared Investment
Interoperability
Radio System Issues
· Aging Dispatch Center Equipment
· Capacity Issues
· Dispatch Center
· Limited Radio Channel Capability
· Regulatory (FCC) Requirements- Narrow band
with by 2013
· Radio Interference
· Non-repeated Fire Channel
Radio System Issues
[] Interoperability--
· Carver County
Adjacent Agencies
- 800MHz
· State Patrol- 800MHz
· Allina Ambulance
· Dakota County- Moving toward 800MHz
Migrating to New System
· Communication- discussion
· Capacity Planning
· 9-1-1 Dispatch stations
· Number of portables (handhelds) and mobiles
(vehicle mounted)
· Police & Fire
· Transit or Public Works?
· "Channels" and "talk groups"
Migrating to New System
· Coverage requirements
· Outside
· In buildings (light, medium and heavy
construction)
· Compatible Equipment (Dispatch Consoles
& Radios)
Migrating to New System
· Technical & System Design
· Hardware (Radios, Towers, Microwave, etc.)
· Software
· Tower Locations (reuse of current, shared, new)
· Cost and Funding
· Capital / Operational
· Funding (Cities / County / Others)
· Policy Decisions & Timing
Where are we at?
· Communication (discussions) Educating
Public Officials & Users
· Councils/Boards & Administrators (City / County)
· Chiefs. (Police / Fire)
· Metro Radio Board
· Jail/LEC includes new 9-1-1 Center
· Increases Center Capacity- (4 positions to 8 positions
and wired for 11)
· New radio consoles are 800 MHz (Metro-ready)
Where are we at?
· Collaborative Discussions with Dakota
County
· Shared Tower Sites
· Timing
· Approval of Metro Radio Board for 9-1-1
Center Staged Implementation
· $35,000.00 Grant from DPS for Planning
and System Design Work
What Needs to Be Done?
· Determine Capacity (Needs)
· Police & Fire
· Transit or Public Works?
· "Channels" and "talk groups"
· Determine Coverage Requirements
(Current Future)
· Outside
· In buildings (light, medium and heavy construction)
· Administrative Community Development process -
"building treatments"
What Needs to Be Done?
· Design System
· Develop Detailed Cost Estimates & Funding
Scenarios
· Apply for grant funds (MRB, DPS, Homeland
Security)
· Begin to set aside funds and build levy capacity
-for CIP or possible bonding
· Establish Cost Shares
What Needs to Be Done?
· Cost Shares- Migration & Operation
· County Costs - general estimate
· Dispatch
· Upgrade Equipment (Budget) ($1,289,000.00)
· Connection to 800 MHz System
· System Design (Technical & Migration Plan)
· Grant Funded ( $35,000.00)
· Broad band Connectivity & upgrading and/or adding of
towers
· 6 to8 Sites total ($7,200,000.00)
What Needs to Be Done?
· Cost Shares
-Migration & Operation
general estimate
· City Costs -
· Mobile and portable Radios (Average per radio
$3,000.00)
· Operational Cost (per radio) plan $500 per
radio
Guidance / Assistance from Cities
Direction? - we don't see any reasonable alternatives
Real Estate
Planning
· Capacity- numbers of radios (now & future)?
· Coverage- "in building" treatments for heavy commercial
buildings?
Timing
· Synchronize with Dakota County?
· Late 2005 to early 2006 plan completed
· Late 2006 to early 2007 migration
