ı In future there will be more 802.11ax networks with spatial and frequency reuse ı One “network” consisting of access point (AP) and one or multiple Stations is a basic service set

(BSS)ı AP service areas can overlap (e.g. apartment buildings)ı STA2 is distorted by traffic in OBSS (overlapping BSS) => less access to the channel

ı CSMA/CA (carrier sense multiple access/collision avoidance): Station checks if channel is free

ı 802.11ax changes: Each AP assigns a “color bit” in the preamble STA reads color bit If STA detects frame from OBSS => raise CSMA

detection threshold => ignore OBSS frames
