"Despite the incredible power of today’s supercomputers, there are many complex computing problems that can’t be addressed by conventional systems. Our need to better understand everything, from the universe to our own DNA, leads us to seek new approaches to answer the most difficult questions. While we are only at the beginning of this journey, quantum computing has the potential to help solve some of the most complex technical, scientific, national defense, and commercial problems that organizations face. We expect that quantum computing will lead to breakthroughs in science, engineering, modeling and simulation, healthcare, financial analysis, optimization, logistics, and national defense applications."

Migration & Cutover Planning
of Your Radio System
www.ebe-consulting.com
APCO Western Regional Conference
March 9, 2016
2. 2 www.ebe-consulting.com
Abstract
When it comes time to upgrade a radio system, the
migration plan and cutover schedule impacts end
users the most.
By identifying and developing a clear migration plan
early on, agencies can use this knowledge to phase
system deployments, develop budget cycles, and
reduce impact to end users.

Speaker Bio
Susan Ronning, P.E., BSEE, MBA
• Member of APCO, IEEE, Women with Moxie
• Volunteer Team leader for Arbor Lodge & Kenton
Neighborhood Emergency Team (ALK-NET)
• EBE Consulting, Principal Engineer
• Previous associations: Tait Communications,
Federal Engineering, L.R. Kimball & Associates,
City of Glendale CA, Motorola
5. 5 www.ebe-consulting.com
Definition
• Soft cutover
- Allows users to return to a previous operational
state with minimal effort
• Hard cutover
- Some or all portions of the system cannot
revert to a previous state due to major
hardware or software reconfigurations
6. 6 www.ebe-consulting.com
The ideal cutover
• A soft cutover allows the existing radio system to
be cutover to the new system with limited impact
to the end users and their operations
• All constraints are alleviated when a new radio
system can be installed and tested alongside the
existing radio system
9. 9 www.ebe-consulting.com
Plan: Technology shift
• Radio system configuration affects user operations
- Major: Conventional vs. trunked operation
- Minor: Analog vs. digital modulation
• Example(s)
- Minor: Add site(s) to existing system; add/ modify
channels to existing system
- Major: Transition from conventional… single site single
frequency transmit vs. multi-site voted or multi-site
transmitter steered-voted or simulcast… to trunked
10. 10 www.ebe-consulting.com
Plan: Operational groups
• Identify each distinct group of users; identify day-to-day
& emergency communications required between groups
• Who talks to whom? When? Why?
• Are these internal departments or neighboring agencies?
• Are communications dispatched or ad-hoc?
- Law, Fire, Medical, Utilities, Transportation
11. 11 www.ebe-consulting.com
Plan: Operational areas
• Identify where each user group operates
• What is their physical area of operations? Citywide?
Countywide? Along a specific route?
• Does location change based on time of day?
• Do groups interoperate with neighboring jurisdictions?
- Federal, State, County, City, District, Area boundaries
13. 13 www.ebe-consulting.com
Technical limitation: Spectrum
• Spectrum, also known as frequencies or channels
• If existing frequencies must be reused…
- Major impact to end users!!
• Will channels be added to the system?
• Is the system migrating to ‘spectrally efficient’ TDMA
modulation?
14. 14 www.ebe-consulting.com
Technical limitation: Backhaul
• “Backhaul” is the microwave, fiber, or leased line
connection between sites; also includes IP routers and
switches or TDM multiplexers
• Backhaul must have sufficient bandwidth (and jitter,
latency, QoS) to support the new system
• If both radio systems will co-exist, then sufficient
bandwidth and network ports for both new and old radio
equipment is required
15. 15 www.ebe-consulting.com
Technical limitation:
Physical space & power
• Radio Sites
- Antenna space on tower; tower loading capacity
- Tower space for more or replacement coax line
- Rack space in existing rack or new floor space in
equipment room; additional equipment power
• Dispatch console
- Space on desk next to existing position; power and
network connections for new equipment
16. 16 www.ebe-consulting.com
Technical limitation:
Physical space & power
• Control stations
- Space and power for new control station on desk
- Antenna installation and associated transmission line
• Mobiles
- If required, physical space and power for 2nd mobile
mounted in vehicle
17. 17 www.ebe-consulting.com
Technical limitation:
Subscriber radios
• Mobile radios capabilities of communicating on existing
and new radio systems allow for simpler cutover
schedule
• Where existing mobiles cannot operate on new radio
system, installations drive the cutover schedule
19. 19 www.ebe-consulting.com
Preparation considerations
1. Identify migration strategy
2. Create project schedule
3. Perform cutover pre-work
a) Perform “make ready” work
b) End user and technical training
c) Define hour-by-hour cutover schedule
4. Develop fallback plan
20. 20 www.ebe-consulting.com
Prepare: Migration strategy
• Analyze technical constraints
- Spectrum, space, power, backhaul
- Console, mobile, and portable capabilities
• Analyze operational constraints
- Operational groups vs. operational areas
- Consoles or radio gateways may be required to
patch old and new radio channels together
21. 21 www.ebe-consulting.com
