Informal World-Wide Survey of APs May 2006 Informal World-Wide Survey of APs Most APs are on chs. 1, 6 and 11. However roughly 25% are located on “other” channels. Jason Trachewsky, Matthew Fischer (Broadcom)

Minimum Channel Separations May 2006 doc.: IEEE 802.11-06/0xxxr0 May 2006 Minimum Channel Separations The distribution of minimum channel separations between APs in each location shows that “individuals” (those not using 1, 6, or 11) are scattered widely across locations. One is likely to encounter usage of the “other” channels. Jason Trachewsky, Matthew Fischer (Broadcom) Jason Trachewsky, Matthew Fischer (Broadcom)

May 2006 Concluding Remarks 25 MHz separation between the control and extension channels does not solve the 20-40 MHz coexistence problem. For the CCA using frame detect (CS) to properly work, both control and extension channels have to overlap with channels used in the 2.4 GHz band. Overlap is not guaranteed based on the survey results presented here. Energy Detect (ED) CCA on the extension channel seems to be a reasonable solution. Jason Trachewsky, Matthew Fischer (Broadcom)
