RFI sources and solutions

Changing technology means that the sources of interference are continuously changing, and this will often mean adopting new technology and techniques. Nevertheless, well-established methodology that is systematically employed will normally serve practitioners well.

Although best practice in installation and maintenance is essential to preventing and minimising Radio Frequency Interference (RFI), this guide doesn't address such aspects.

Regulations

Regulatory measures are in place to prevent unacceptable levels of RFI pollution to the New Zealand radio spectrum resource.
