• Define an alternate PHY layer for 802.15.4 with only those MAC modifications needed to support the PHY layer implementation
• Support 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 deployments• Provide mechanisms that enable coexistence with other systems in the same
band(s) including IEEE 802.11, 802.15 and 802.16 systems

Define an alternate PHY layer for 802.15.4 with only those MAC modifications needed to support the PHY layer implementation
Overview of Proposed PHY Layer• Only make changes to 802.15.4 that are necessary to address PAR• Use same frequency bands• Use existing modulations• Use existing data rates
