Throughput and Repeaters
It should be noted that if you are using repeaters to extend the range, there will be a reduction in throughput for
each repeater hop. The 40-MHz Turbo channels rarely provide better throughput than the 20-MHz in the real world
because they occupy a larger portion of the 2.4-GHz band and are more prone to interference. For RSSI, see
“4.1 Connectivity.” For information on checking interference or noise, see “4.2 Channel Survey (Utilization).”
The following table shows the drop in throughput for each hop and for each of the channel widths.

4.5 Statistics
The Statistics webpage is used for advanced debugging of 245U-E. This webpage details the state of the 245U-E
and performance information. This page is useful to ELPRO technical support in diagnosing problems with the
module.
