NATIONAL BROADBAND NETWORK CONCEPTUAL DESIGNS

Presented to the FCC

Washington DC

March 3, 2011

By

John S Powell, Chair

NPSTC Interoperability Committee

Opening Note• While the pictorials in this presentation could be misconstrued as an architecture, they are intended to be only high level concept drawings to help illustrate the difference between the network‐of‐networks approach and a single national network.

• For real‐world implementation, a great deal of engineering analysis would go into every component of each drawing, regardless of approach, to determine such things as optimal core location, interconnection of the core network, etc.

Network‐of‐Networks Solution• Multiple IDs (PLMNs), one for each Public Safety Network

– Forces roaming between public safety networks, and all associated engineering and business expenses for roaming replicated between each network

– May not be possible to get many IDs from ATIS IOC

• Inconsistent user subscription fees for each network and roaming fees between PS networks (TBD)

• Duplication & Overbuild = unnecessary expenses• Upgrades inconsistent across Public Safety networks• Public safety roaming also required onto commercial 

networks– One agreement between each Public Safety Network, and each 

supported commercial network, or– An agreement between each Public Safety Network and a 

Clearing House & Roaming Hub.

One Nationwide Network

• No public safety roaming on a nationwide network that deploys a single Network ID (PLMN)– Consistent user subscription fee regardless of user location based on nationwide agreement (TBD)

• Upgrades nationally consistent

• Public safety roaming only required onto commercial network(s)– A single agreement with a clearing house can be used versus multiple agreements in a network‐of‐ networks approach

In Summary

A flexible , reliable and vibrant National Broadband Network will allow responders and support staff to dramatically increase effective and efficient support for daily operations and incident response by enhancing coordination & situational awareness, reducing response time, and promoting effective management through timely delivery of needed information, thus ensuring continuity of government and increasing the safety of life and property.

Remember Our Mission!

• Bring to a successful conclusion every incident so that all responders and support staff can return safely to their families at the end of every day, and

• To the maximum extent possible, ensure that the public we serve can likewise return safely to their families and homes at the end of their day.
