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: No: 1 Abstain: 15
This document explains simulation scenario addition to FR&EM document.

3. 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

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

5. 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 n BSS
Both 11ac have the same bandwidth (40MHz or 80MHz)
