About the Presenter
• 16+ years experience as agency mid-level manager, consultant, and vendor in the Public Safety and Critical Infrastructure communications industry
• Professional Engineer (Electrical) holds BSEE and MBA; member of APCO, IEEE, and Civil Air Patrol
• Desire to share wealth of knowledge accumulated in this industry to further Public Safety and Critical Infrastructure equipment, systems, and capabilities

Purpose
Today more than ever, Public Safety agencies are stretched to do more work with less staff.
“How to Successfully Project Engineer a Radio System” provides the guidance needed to understand the process involved in undertaking a new or replacement radio system project.
Applies to “almost” any project; with a unique spin.

What’s Unique? 3rd Party Systems Integration• Radio system projects aren’t usually limited to two-way
radio system. Other components include…- Radio technology- RF subsystem: spectrum, site locations, and RF coverage- Backhaul microwave and/ or fiber- Baseband IP or TDM layer- Dispatch consoles- Subscriber mobiles, portables, control stations- Logging recorder- Monitoring and alarms- Site shelter & tower space, primary and backup power- Spectrum availability

Project Scope Driver - DESIGN
1. Define the problem statement
2. Identify systems to integrate
3. Understand the potential migration strategy

Project Scope Driver – DESIGN (cont.)1. Problem Statement
- Identified through needs assessment stage
- Who are the users? Where do they talk? Who do they talk to? How are their workgroups organized? What are their issues?
- Identify your stakeholders & keep them informed throughout the ENTIRE process…• User perception always outweighs technology capability
- Is equipment and/or technology obsolete?- Identify whether they need or want changes to…
• Coverage, Capacity, Operability, Interoperability

2. Identify Systems to Integrate• Radio technology• RF subsystem: spectrum, site locations, and RF coverage• End user devices: dispatch consoles, mobiles and
portables• Backhaul subsystem: microwave, fiber, leased lines• Baseband subsystem: TDM or IP• Monitoring and recording: Logging recorder• Site shelter & tower space, primary and backup power• Spectrum availability

Project Scope Driver – DESIGN (cont.)
3. Understand the potential Migration Strategy- Identified through technical assessment stage
- Ideal Migration: Low Risk; Non- or Minimal affect to service; Seamless user transition
- In other words: replacement radio system to be installed, configured, and tested in whole prior to cutover from existing radio system; requires duplicate:
• Site: tower space, rack space, backhaul, power; • Subscribers: backward compatible or potential duplicate
installations• Spectrum

Project Scope - PROCURE
• Sole source contract or bid response?• Equipment only or equipment with services?• Single system procurement or turn-key multi-
system integration?
© 2013 Tait Limited19
Project Scope - IMPLEMENT
• In-house, contracted, or consultant- Project management- Technical advisor
• Technicians or others available to…- Escort vendor engineers/ technicians/ installers- Provide operational use information- Provide legacy system knowledge transfer- Oversee site and system equipment configuration and
tests, site installs/ removes

Project Scope - MAINTAIN
• Internal maintenance personnel• Contracted maintenance personnel• Vendor support and maintenance agreements- Hardware- Software
• On site preventative and emergency services• Managed Services contract
