Home Network Simulation Scenario with OBSS Month Year doc.: IEEE 802.11-yy/xxxxr0 September 2009 Home Network Simulation Scenario with OBSS Date: 2009-9-22 Authors: Yasushi Takatori (NTT) John Doe, Some Company

September 2009 Introduction Inclusion of additional simulation scenario for OBSS in home network is agreed by Strawpoll as follows[1]. Do you agree that home network scenario with OBSS should be included in the Functional Requirements and Evaluation Methodology document? Yes: 22 No: 1 Abstain: 15 This document explains simulation scenario addition to FR&EM document. Slide 2 Yasushi Takatori (NTT)

Home Network Evaluation Scenario September 2009 Home Network Evaluation Scenario To simplify OBSS scenario, the following effects are focused on. Overlapping with 11ac Overlapping with 11n Effect of hidden terminals in OBSS Throughput degradation from isolated Home Entertainment scenario Evaluation model BSS A: In-Home entertainment application BSS B: 11ac with 3 STAs BSS C: 11n with 3 STAs Room walls are inserted to evaluate effect of hidden terminals Slide 3 Yasushi Takatori (NTT)

AP and STA locations Attenuation factors of room wall and outside wall are TBD. 11n In-home entertainment application 11ac

Channel Assignment BSS C BSS A,B Case 1 Frequency 80MHz BSS C BSS A,B BSS A is identical to the BSS in TGac scenario #3 BSS B is an 11ac BSS BSS C is a lower 40MHz 802.11n BSS Both 11ac have the same bandwidth (40MHz or 80MHz) Frequency 80MHz BSS A,B BSS C Case 1 Frequency 80MHz BSS A,B BSS C Case 2

Traffic flow at overlapping BSS B Flow number 1 and 12 in simulation scenario #3 are considered. Flow No. STAs (Source/Sink) Source Location (meters) Sink Location Channel Model Application (Forward Traffice / Backward Traffic) Application Load (Mbps) (Forward / Backward) Rate Distribution MSDU Size (B) Max. Delay (ms) Max. PLR 1 AP / STA1 (0,0) (0,5) C LC Video / VoD control channel 150.00 / 0.06 Constant, UDP / Constant UDP 1500 / 64 10 / 100  10^-7 / 10^-2 12 STA4 / STA10  (-7,7)  (10,10) Local file transfer Max. 1Gbps TCP 300 Inf.  N/A

Traffic flow at overlapping BSS C Flow No.1 in BSS B is changed to Flow No.1 of 802.11n scenario #1. Flow No. STAs (Source/Sink) Source Location (meters) Sink Location Channel Model Application (Forward Traffice / Backward Traffic) Application Load (Mbps) (Forward / Backward) Rate Distribution MSDU Size (B) Max. Delay (ms) Max. PLR 1 AP / STA1 (0,0) (0,5) C HDTV(Video / Audio) / VoD control channel 19.2 / 0.06 Constant, UDP / Constant UDP 1500 / 64 200 / 100  10^-7 / 10^-2 12 STA4 / STA10  (-7,7)  (10,10) Local file transfer Max. 1Gbps TCP 300 Inf.  N/A
