A Voltage Standing Wave Ratio (VSWR) of 1:1

An impedance mismatch between components in the RF system

Cross-polarization of the RF signal as it passes through the RF system

The use of cables longer than one meter in the RF system

High output power at the transmitter and use of a low-gain antenna

Transmitting station’s power source

Receiving station’s radio sensitivity

Free Space Path Loss

MAC layer encryption

Transmitting station’s output power

Temperature in the Fresnel zone

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
