Radio Throughput
Below is a table showing the maximum TCP/IP throughput based on channel selection and receiver signal level.
There are five channel bandwidths (20, 10, 5, 2.5, & 1.25MHz). These throughput estimations are based on perfect radio conditions, i.e., little to no outside radio interference present while data is being passed

Throughput and Repeaters
It should also be noted that if using repeaters to extend the range there will be a reduction in throughput for each repeater hop. The following table shows the drop in throughput for each hop and for each of the channel widths.
