2. doc.: IEEE 15-00-0815-00-004g TG4g - SUN November 2009 Phil Beecher, Beecher Communications Consultants Ltd Slide 2 TG4g-SUN PAR Scope This Standard defines an amendment to IEEE 802.15.4. 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 kbits per second but not more than 1000 kbits per second 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 802.11, 802.15 and 802.16 systems

3. doc.: IEEE 15-00-0815-00-004g TG4g - SUN November 2009 Phil Beecher, Beecher Communications Consultants Ltd Slide 3 TG4g-SUN PAR Purpose To provide a global standard that facilitates very large scale process control applications such as the utility smart-grid network. 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 (See explanatory notes in Section 8.1 Doc#15-08-705).
