3.5.1 Wi-Fi Details > Devices table
The Devices table presents a list of devices currently communicating with the same access point on the
connected channel. It is a “best-effort” estimation based on periodic samplings of Wi-Fi packets on the
network. Because the unit cannot monitor all packets continuously, the results are only accurate for the
time periods that it observes. It is possible that connected devices may not appear in the list at all if their
traffic occurs outside of the sampling periods.
All numeric results represent the most recent sampling period only; that is, the unit does not average
previous results. However, a detected device always remains in the table for at least 30 seconds, even if
it is not detected in future samples. When a listed device has no representation in the most recent
sample, all numeric results display as zero (0) because the unit has no data for calculations. Note that
sampling periods correspond with the regular refresh periods of the main Details screen, as all data for
both screens is collected during these times.
The Devices table includes the following columns:
Phy Rate Bit rate of the physical layer bitstream, in Mbps. This value is related to the basic
number of bits that can be transported by the QAM modulation of the analog
waveforms. A stronger signal typically means that QAM symbols can carry more
bits and thus the transport layer data throughput may be higher. Therefore, this
value may provide some indication how well the link can carry digital data.
RF Util
RF Intf
Percentages of time that the channel is occupied with usable wireless packet data
and unusable interference. While measuring, the unit performs a cursory analysis
of all activity on the channel, above a set noise threshold. The utilization rate
represents the percentage of total measurement time that the channel showed
any activity. The interference rate represents a subset of the utilization rate, during
which the channel was occupied with activity that could not be decoded as valid
Wi-Fi traffic (in other words, excessive noise.)
Note that the utilization rate applies to the entire channel and all connected
devices, not just traffic that involves the unit. On any given channel, all devices
must share time using CSMA technology to avoid collisions.

Estimated total number of hosts connected to the current access point, including
the unit. This count is generated by the same process that populates the Devices
screen and may not be precise. For more information, see Wi-Fi Details > Devices
table on page 3-15.
