If the V-Perf Throughput Threshold is enabled from the
Setup
menu (see
), the dial and bar graph
will take on a green or red color to indicate Pass or Fail statuses.
Green
: Indicates that the throughput rate is higher than the threshold setting, therefore the test passes.
Red
: Indicates that the throughput rate is lower than the threshold setting, therefore the test fails.
Blue
: Indicates that no Pass/Fail throughput threshold is configured. V-Perf Throughput Threshold is disabled from the
Setup
menu.

11.2.2 Data Rate vs. Phy Rate
When comparing achieved TCP or UDP data rates to the WiFi Physical Layer rate, the following considerations should be taken
into account:
Achieved Data rate vs. Max Phy rate
The Maximum Phy Rate advertised by the Access Point is the
theoretical maximum
physical layer rate supported. For
example, an 802.11ac 4x4:4 AP configured with 80 MHz channel width can achieve up to 1733 Mbps Phy rate. WiFi clients
often have lower physical layer rate capabilities; they are often limited to 1 or 2 antennas or do not support the latest
802.11ac standard.
The MIMO (Multiple Input Multiple Output) technology (802.11n, 802.11ac) allows multiple parallel data streams.
The number of MIMO streams depends on the number of device antennas (AP and Client).
The WiFi channel width depends on AP/Client capabilities and configuration.
