Note: a GI of 800 ns results in slightly higher data rates (up to about 10% higher).

The average throughput per station is directly proportional to both an aggregate BSS throughput and an area throughput. A fifth percentile measure of the per station throughput, that is, a measure of the throughput achieved by 95% of the stations, may be used to determine that a desired distribution of throughput among a number of stations in an area is satisfied. Since the values of the metrics will depend on the scenario, the IEEE 802.11ax amendment focused on a relative improvement of the metrics compared to previous IEEE 802.11 revisions (e.g. IEEE Std 802.11‐2012 in a 2.4 GHz band and IEEE 802.11ac in a 5 GHz band). The amendment includes a capability to handle multiple simultaneous communications in both spatial and frequency domains, in both UL and DL directions [2]. Design goals include robustness in outdoor channels, higher indoor efficiency, and the use of OFDMA. Chapter 5 will expand on these concepts.
