Frequency Planning

From IPS_FAQ

Jump to: navigation, search

Frequency Planning is a highly complex subject with many interrelated variables. Getting a collection of radio based Radio Microphones, Talkback and IEM all working together in the same location without mutual interference can be a nightmare. It is far more complex than just picking different random frequencies within a band for each transmitter.

There is software available to aid frequency planning but for a job involving more than a few frequencies it is probably best to utilise the planning expertise of groups like JFMG whom you will probably have to contact anyway for licenses.
