Main Status Screen - Client Unit - Solectek skyway User Manual

Tx Streams – This indicates whether the unit is being operated with 1 stream or 2 streams of date
over the RF channel. The ACM operation is indicated by the designation of an 'A' in parenthesis.
Fixed operation is indicated by an 'F.'
Local Statistics – These are values experienced by the client unit. Receive Column details values at
the client unit receiver and Transmit Column details values at the client unit transmitter.
Throughput – Please note that the throughput value displayed here do not refer to the radio link
capacity. Rather, it refers to the instantaneous throughput over a short time period measured by the
unit. The value here is meaningful for estimating the traffic amount if such traffic can be sustained
over some time period. Due to framing overhead, actual IP throughput will be less.
Total Frames: Total number of aggregated RF data frames received and sent by the unit. Note:
this number should not be expected to match the Ethernet frames count. Packet framing,
aggregation and QoS operations will all affect the manner in which data is transported from Ethernet
to RF port.
Data Packets: Total number of data packets prior to aggregation, on the transmit side, and
following de-aggregation, on the receive side.
Receive Errors: Total number of Errored Frames received by the local unit.
Tip: When diagnosing link problems, it's useful to clear the RF statistics and allow 5-20 minutes of
new data to accumulate. This will provide an accurate picture of the current link conditions. On
occasion, it may be useful to sample a longer time period, up to 24 hours in some cases, as the
influence of external interference sources can vary across time due to usage patterns.
Note: RF Frames which are significantly damaged can not be accurately attributed to a paired radio
and will not affect this count.
Transmit Errors: Total number of frames transmitted by the local radio that were not successfully
acknowledged by the remote radio.
Errors of this type can be attributed to two causes: (a) Data packet not received by remote radio, or
(b) Acknowledgement packet from remote radio not received by local radio.
Tip: Because the SkyWay Access radio is a TDD system and uses the same frequency for both
transmit and receive, it is often instructive to compare RX and TX error counts on both sides of the
link so that RF impairments can be isolated to the appropriate link direction and radio.
For example, if Radio A has a large number of TX errors and Radio B has a large number of RX
errors, one could conclude that the RF link from A => B was impaired. Sources of potential
interference at Radio B could then been investigated.

The basic status of a client unit can be viewed in the Main Status screen and is slightly different from
that of the base station, as shown below:
