Identifying an interfering signal means you’re half way to solving your network problem, however the hard part may yet remain – finding the source. This can be particularly tricky in an urban environment, where congestion, large buildings, and multiple networks reside. Using the proper direction finding methods can help you locate the interference cause faster and more efficiently.
In cities, the main propagation paths that the signal follows will probably be multiple bounces off buildings. In this scenario, a good method is to walk to an intersection and point your antenna (either a Yagi beam, log-periodic, or flat panel directional antenna) attached to an Anritsu Spectrum Master™ down each road. To find the best direction to the emitter, follow the strongest signal until it there is a radical change in the direction in which the strongest signal arrives.
