4 doc.: IEEE 802.11-10/1305r0 Submission Similarities with 802.11 Same bit-to-symbol mapping Same convolutional encoder (1/2 rate, constraint length K=7, generator polynomial g0=133 and g1 = 171) Same puncturer for ¾ rate coding Same interleaver Option 2 has the same number of active tones (52) and same number of pilot tones (4) Similar STF, LTF, Header, Tail and Pad structure 4 Emmanuel Monnerie (Landis+Gyr), John Buffington (Itron) November 2010

5 doc.: IEEE 802.11-10/1305r0 Submission Differences with 802.11 802.11 OFDM narrow band options are based on operating clock shrink: tone spacing reduction, guard interval increase 802.15.4g options are based on different FFT sizes: constant tone spacing and cyclic prefix 5 Active Tones Tone SpacingGuard Interval142652104 312.5 kHz0.8 us 802.11 20MHz 54Mbps 156.25 kHz1.6 us 802.11 10MHz 27Mbps 78.125 kHz3.2 us 802.11 5MHz 13.5Mbps 39.0625 kHz6.4 us 802.11 2.5MHz 6.75Mbps 10.41667 kHz24 us 802.15.4g 200kHz 300kbps 802.15.4g 300kHz 600kbps 802.15.4g 600kHz 800kbps 802.15.4g 1.2MHz 800kbps 802.11ah ?

6 doc.: IEEE 802.11-10/1305r0 Submission Next steps to work on… Analyze and resolve potential issues around 802.11 MAC and TG4g PHY interface (CRC, PHY settings, etc.) Explore some new options with data rates between 800kbps and 6.75Mbpses? Further scaling down of 802.11 and/or scaling up TG4g options with data rates above 800kbps. Slide 6Emmanuel Monnerie (Landis+Gyr), John Buffington (Itron) November 2010
