Use of larger frame sizes results in greater throughput in low interference environments.

BSS support for 65 KB A-MPDUs will increase the maximum data rate available to client devices.

In 802.11ac, changing the security mechanism from WPA2-Personal to WPA2-Enterprise will enable the VHT MCS rates.

Compared to an Independent BSS, an Infrastructure BSS can provide almost twice the throughput between wireless nodes.

Use of short guard intervals improves reliability and throughput in high multipath environments
