Integrated Critical Communications Infrastructure for Smart Grid at Connectivity Week
On the 25th May 2011 at the Connectivity Week conference in Santa Clara, California USA , there was a very informative session and the main focus was on wireless networks to be used for Smart Grid Critical Communications.
“ Critical communications infrastructure that supports the likes of military , emergency services and law enforcement is protected to serve the public good and is not subject to everyday market focus.
Electricity is a strategic asset for all modern economics and adequate safeguards are needed to protect grid in much the same way.
One way of doing this is to allow utilities to share the dedicated spectrum and radio frequencies that support that support essential services.
The purpose of this session is to elucidate the rationale for utilities use of wireless to send and receive critical communications related to Smart Grid. “ [ Allan Weissberger ]
The key characteristics of the Critical Communications Infrastructure as highlighted by Kat Shoa from The Directive Group are :
- Supports military , emergency response and law enforcement
- Fundamental to public safety during emergencies
- Spans broad geographical areas
- QoS of utmost importance
Public vs. private networks
Security : physical security , data security
Integration / deployment timelines
Howard Liu , Network Architect , Southern California Edison (SCE)
His presentation shed light to what cutting edge utility has done to build and operate its own network.
His suggestions were :
- Utilities have to build their own integrated communications network for applications eg. Disaster recovery
An integrating different sub-networks as a key issue
The other key points highlighted by Howard were :
SCE’s Integrated Critical Communications Infrastructure has a vision of a Layered Communications Architecture
Utilities had to build their own Integrated Critical Infrastructure for Critical Applications
SCE will consider complementing that with a Telco company going forward
