== Mitigating the Effects of Distant Interferers ==

One of the key challenges in running over-the-air experiments is accounting for uncontrolled external interference. While there is no single method for keeping unintended interference from polluting research results, there are a number of techniques that help mitigate harmful effects.

1. The [wiki:HardwareUsersGuides/WARPv3/RF MAX2829 transceiver] can be tuned to a variety of different center frequencies in the 2.4GHz and 5GHz bands. Before constructing your over-the-air experiment, it is a good idea to scan for Wi-Fi networks around your setup. There are many freely available tools for determining which channels are being used and how powerful the networks using those channels.

The above figure shows an example of what you might see after this scan. Given the occupied channels and their relative powers, we can see that 2.4GHz Channel 1 might be a good selection for a channel to run an experiment in.
