What do you need as an Utility Company?
“In a large scale crisis situation or a blackout involving multiple public safety
agencies and lack of Power Energy, immediate access to a common radio
communications platform that allows workers to efficiently communicate is
critical for effective operations”
The Answer is simple, you need a well designed

What Is a MCRN?
• A single platform two-way radio network that supports organizations throughout a
given geographical area
– Exclusively used by your company – not shared with commercial users
– Not open to the public
– Coverage area can be citywide, region wide or nationwide
– High Availability, 24x7 (typical goal of 99.999%)
– Highly Resilient: multiple levels of redundancy to guarantee that the failure of
one of the critical components of the network does not compromise the
integrity of the communications
• A single platform network shared among different organizations which will allow users to
interoperate among those organizations

Approved)
• Utilities too
• Are you going to operate in Hazardous
Locations?
• If so Are the manufacturer devices FM
Approved?
• Regulation is SPECIFIC & differs from
Country to Country

Key Points to consider:
Safety
• Ensure that your radio won't cause a fire
or explosion in an area where flammable
or combustible materials (such as gases,
vapors, dusts, or fibers) are present, it
must be designed using various methods
of protection.
• Is your supplier ready to meet this
requirement?

Key Points to consider:
Safety
• Service in Intrinsically Safe (I.S.) devices
must follow specific procedures
• Is your Supplier Service Center properly
certified* to repair an I.S. radio?
• Always verify FM GLOBAL or CENELEC
• In USA: http://www.fmglobal.com
*There are tight specific regulations to provide service in
I.S. devices

Key Considerations for MCRN
• MCRN should be an independent, company-only private network,
because of:
– The need for high Grade of Service
•
•
Network Availability
Fast performance (fast call set-up time)
– The need for full control of the network
•
Allows for network design for security, system reliability and network resilience
– Security
– Network capabilities and features
•
E.g. Emergency call with priority call, Dynamic Regrouping, Broadcast call, etc.
– Coverage

Benefits of MCRN - (1)
• Interoperability
– Common network allows agencies to intercommunicate
– Facilitate inter-communication among different
agencies, especially during time of crisis
• Cost Savings
– Economies-of- scale for using common network
• The larger the network and users, the most cost-effective it
becomes
– Greater functionality at a lower lifetime cost
– Access to a unified radio network without a high
upfront cost of capital

Benefits of MCRN - (2)
• Security
– All information exchanged are within the exclusive
government network
– Not open to public
– Can be equipped with high grade of network security (e.g.
encryption)
• High Reliability & Availability
Network can be designed to support:
– High availability of system resources to allow immediate
access to available channels, specially during emergency
situation
– High levels of Grade of Service
– High reliability of system to ensure that the system has
virtually no down time.

How a Digital Standard Meet MCRN
Requirements
Requirement:
•Privacy within each organization
while sharing a common network
Multiple agencies sharing a common
network
Solution:
• Each agency sees the VPN network as if it is
their own closed network
• Users can not “see” outside their VPN
network, Others can not “see” into their VPN
• Interoperability features for multi-agency
communications

Summary
• MCRN allows interoperability among government agencies
supporting both day-to-day and emergency operations
• Due to its high requirement for security, reliability and performance,
MCRN shall be built as private, company-only network
• Digital Trunking Standards have been proven as a solution to
MCRN with its comprehensive interoperability and mission critical
features
• To successfully implementing MCRN network, experiences partner
is key to successful implementation:
– Motorola has proven solution & extensive experiences in
deploying MCRN solutions worldwide
