Diagnostics/RF Throughput
The RF Throughput utility enables the direct testing of link performance between an Access Point and
a remote End Point. The test can be initiated from either side of the link.
Enter the Device ID for the radio on the opposing end of the link.
Set the test for:
• Transmit Only; i.e. from the local radio to the remote radio only.
•
Receive Only; i.e. from the remote radio to the local radio only.
•
Bi-directional; i.e. from local to remote and remote to local.
Enter a Test Duration in seconds and press the Test button.
Note
When using this utility on a cnReach N500 radio, it is necessary to select which Source Radio (RF Module) to use for the
test.
Once initiated the link will be saturated with test packets at the RF protocol level. The link will be
temporarily unavailable to normal Ethernet traffic during the test.
Each successful test will report Transmit and Receive throughput, in kbps, for both the local and remote
radios at opposing ends of the link. Faster modulations and larger packet sizes produce more
throughput.
Note
RF throughput will be less than the RF Data Rate due to RF protocol overhead, but higher than TCP throughput due to
TCP protocol overhead.
Dropped Packets may indicate elevated noise levels at one or both sites. In a noisy environment,
reducing the packet size (Max Payload Bytes) and using a faster modulation can help the Radio get on
and off channels quicker, increasing effective throughput.
