Smart Grids: the context
Smart Grids: What is it?
• Smart Grid is not a system! It is the concept of modernizing the electrical grid
with ICT technologies.
• The smart grid should manage power production, transmission, distribution
and consumption.
Social duty to contain climate changes
through reduction of CO2 emissions

Smart Grid concept: the similarities to what
happened in the TLC network:
►
In the eighties from analog to digital : the
network equipment became “Smart”

BroadBand and UltraBB benefits for the Smart Grid
• Growing numbers of endpoints requiring connectivity in the smart grid -> huge
increase of amount of data to be trasmitted. Narrowband will not be sufficient:
• FCC (National Broadband Plan) estimation 200-500 Kbps;
• Our experience (Energy@Home Project): 100 kbps OK for the very basic functions!
Large scale deployments will need much more!

Network: Next Generation Access Network (Fiber Optics)
Network: Mobile Ultrabroadband HSPA+ and LTE
LTE is the evolution of GSM, UMTS, HSPA that improve the quality of mobile broadband service
enabling new applications, bandwith consuming, also “On the move”.
With the Next Generation Access Networks, high bandwith will be available also to SME. This
will enable a new generation of IT applications!
