Optimization of the link involves trying different settings of channel sizes and power:
- Long links: For links over 10 miles / 22km: Smaller channel size 20MHz is almost certainly going to work best on a link of this distance. You should try 20MHz and then compare to 40MHz to compare the throughput with each size.
- Short links can use a wider channel size: 40 to 80 MHz, to get more throughput (as long as there is not too much interference). Experiment with the channel size and see which one gives you the most throughput.
- Power level: Adjust the power to see if you get more throughput by adjusting up and down
Alignment: Optimize the alignment by making very small changes right and left, up and down and watching the reaction of the throughput.Author: George Hardesty
