Interference analysisJDA has the ability to analyse interference caused by a number of different RF sources originating from anywhere in New Zealand. By applying CCIR recommendations and appropriate protection ratios we can indicate areas where interference will cause problems to other services. If a new service is being introduced, we can predict its impact on similar, existing services, and predict its coverage in the presence of these.

Combined with a population analysis we can indicate the number of people likely to be affected by interference. 

Often, a detailed interference analysis can be a vital part of a successful license application for spectrum.
JDA has vast experience in this area as we were major contributors to the VHF channel plan and entirely responsible for the TV4 (C4) channel plan
