(2) Frequency availability around the world should keep being added or altered by each regulatory authorities continuously after now. (3) 700MHz-1GHz spectrum will keep containing similar and useful, but simultaneously diverse global bands for SUN application even in the future. (4) Possible scalable Data Rate and Bandwidth of OFDM have to be instrumental for future adaptation of novel frequency availability, and for the legacy interference avoidance even in case of migration from NBFH systems.

doc.: IEEE g Submission Jul. 15, 2007 Shusaku Shimada, Yokogawa Co.Slide 3 IEEE g PAR : Scope This Standard defines an amendment to IEEE It addresses principally outdoor Low Data Rate Wireless Smart Metering Utility Network requirements. It defines an alternate PHY and only those MAC modifications needed to support its implementation. Specifically, the amendment supports all of the following: – Operation in any of the regionally available license exempt frequency bands, such as 700MHz to 1GHz, and the 2.4 GHz band. – Data rate of at least 40 kbps but not more than 1000 kbps. – Achieve the optimal energy efficient link margin given the environmental conditions encountered in Smart Metering deployments. – Principally outdoor communications – PHY frame sizes up to a minimum of 1500 octets – Simultaneous operation for at least 3 co-located orthogonal networks – Connectivity to at least one thousand direct neighbors characteristic of dense urban deployment. Provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE , and systems.

This amendment supports large, geographically diverse networks with minimal infrastructure. –Smart Metering Utility Networks can potentially contain millions of fixed endpoints. –The communication range, robustness, and coexistence characteristics required for this class of application have not been met with existing 802 standards. Need for the Project: –The need for a standard to promote orderly and quick evolution of smart-grid networks has been recognized in the recently passed energy legislation by the U.S. Congress (EISA 2007; Energy Independence & Security Act of 2007), which calls on National Institute of Standards and Technology (NIST) to work with standards bodies (such as IEEE) to develop protocols and standards for the smart-grid network. In the EuropeanUnion, the need is no less urgent and similar standardization mandates, such as the EU's 20/20/20 plan, are in process worldwide. –The responses received by and presented to the 15.4g Study Group indicate an already large and rapidly growing market for wireless Smart Metering applications that fit the objectives of , but are not satisfied by existing IEEE 802 standards. –Utility networking and very large scale industrial applications have requirements to keep infrastructure to a minimum, scale to millions of nodes across diverse geographical environments, and do so with carrier grade reliability. To reach every node in the network a Wireless Smart Metering Utility Network needs the capability to vary radio range while providing for high spectral reuse.
