4 doc.: IEEE 802.11-12/108r0 Submission Smart Grid Characteristics Controlled deployment Large number of nodes High aggregate throughput requirement Relatively low data rate requirements Example 25’ utility pole mounted AP 5’ high electric meter Hata suburban model Maximum allowed radiated power under FCC 15.247 rules Jan 2012 ItronSlide 4 This refers to 1MH vs 2MHz waveforms

5 doc.: IEEE 802.11-12/108r0 Submission Applicability to Smart Grid Coverage cost – longer range Aggregate throughput – more channels Overlapping networks – more channels Jan, 2012 Slide 5Itron

6 doc.: IEEE 802.11-12/108r0 Submission Coverage cost example Jan 2012 ItronSlide 6 2MHz waveform bandwidth require 100% higher equipment cost

7 doc.: IEEE 802.11-12/108r0 Submission Aggregate vs single link throughput Jan 2012 ItronSlide 7 1MHz waveform bandwidth enables higher aggregate throughput

8 doc.: IEEE 802.11-12/108r0 Submission Overlapping networks example Jan, 2012 Slide 8Itron 1MHz waveform allows three overlapping networks

9 doc.: IEEE 802.11-12/108r0 Submission Conclusion 1MHz channels better fit for use case 1a, Smart Grid application –Low coverage cost –Higher aggregate throughput –Overlapping networks Jan, 2012 Slide 9Itron

10 doc.: IEEE 802.11-12/108r0 Submission Straw Poll: US Channelization (902 – 928MHz) Slide 10 Yes: No: Abstain: Jan 2012 902 MHz 928 MHz 2 MHz 4 MHz 8 MHz 16 MHz 1 MHz
