3 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Define an alternate PHY layer for 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 , and systems Scope/Goals of TG4g

4 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Define an alternate PHY layer for with only those MAC modifications needed to support the PHY layer implementation Overview of Proposed PHY Layer Only make changes to that are necessary to address PAR Use same frequency bands Use existing modulations Use existing data rates Proposal to Address Goals of TG4g

5 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Support operation in any of the regionally available license exempt frequency bands, such as 700MHz to 1GHz, and the 2.4 GHz band No changes to needed already supports the following bands 868MHz, 917MHz 2450 MHz Proposal to Address Goals of TG4g

6 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Data rate of at least 40 kbps but not more than 1000 kbps No changes to needed already supports 20kbps 40kbps 100kbps 250kbps Proposal to Address Goals of TG4g

7 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Achieve the optimal energy efficient link margin given the environmental conditions encountered in Smart Metering deployments No changes to needed Proposal to Address Goals of TG4g

8 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Principally outdoor communications No changes to needed Proposal to Address Goals of TG4g

9 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Proposal to Address Goals of TG4g PHY frame sizes up to a minimum of 1500 octets Changes are needed to needed Change aMaxPHYPacketSize to 2047 octets Change PHY Header to two octets to allow larger payload Could expand Frame Check Sequence

10 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Simultaneous operation for at least 3 co-located orthogonal networks No changes to needed 27 channels are specified now 10 channels are specified in the 917MHz band Proposal to Address Goals of TG4g

11 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Connectivity to at least one thousand direct neighbors characteristic of dense urban deployments No changes to needed Proposal to Address Goals of TG4g

12 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Provide mechanisms that enable coexistence with other systems in the same band(s) including IEEE , , and No changes to needed Proposal to Address Goals of TG4g

13 May 2009 Doc: IEEE g Submission Scott Weikel, Elster Electricty Conclusions IEEE is widely used in many successful applications is interoperable (within a frequency band) PAR for 4g amendments listed only a few improvements needed
