I'm finding hard to keep up here....the Smart a Grid Hanbook is quoted everywhere as the way to go....so we have mass rollout of gps and then later broadband .....I'm a bit lost at the moment. Nothing new.
"Conclusions
The communication architectures presently deployed for smart metering include intermediate entities such as data concentrator units/gateways and creation of a dedicated parallel communication network for the electric utility which they have no expertise in maintaining and upgrading as new communication technologies are evolving at a faster pace. This also involves use of wireless spectrum which is a limited and expensive resource in every country today. Experiences from around the world indicate that none of the communication solutions presently deployed for smart metering have 100% reliability despite having a dedicated network. These architectures not only increase the total cost of ownership but also fail to offer reliable, scalable and interoperable last mile connectivity.
In today�s world where internet is everywhere, smart meters and smart appliances could be connected directly on internet; and utility�s HES can leverage internet to collect the meter data on the server and the MDMS can integrate that with other applications. In other words, the broadband internet that is present in almost all homes, buildings and campuses, can be used for providing last mile connectivity for smart metering. By doing do, devices such as data concentrator units, gateways and in-home displays will not be needed and highly reliable, scalable and interoperable last mile connectivity can be provided. Wherever there are no Wi-Fi, the electric utility may provide Wi-Fi which will be cheaper than other last mile connectivity options.
In the IPv6 regime where every meter can have an IP address, the proposed IP Metering solution can offer multiple benefits to utilities and governments:
 No need for a parallel telecom infrastructure � huge savings in cost of deployment and maintenance for the utility
 No need for separate spectrum for utility applications � instead government can allocate that spectrum to telcos and/or other users for additional revenue
 More reliability, scalability, security and capability to monitor and control � IP networks can be monitored in real time which itself
