What is an interference impact certificate (IIC)?
The IIC is not defined in the Act nor in any subordinate legislation, which only refers to a certificate under s.145 (3). However, through common usage the term IIC has come to mean a specific kind of certification on the R070 (Application for Device Registration Form) to the effect that the device complies with the device boundary calculation set out in the s.145 (4) determination. This means that (assuming the device also complies with all other licence conditions) the device is deemed not to cause unacceptable interference. An IIC is submitted by an accredited person on behalf of a licensee with an application to register a device under a spectrum licence. Devices can be registered without an IIC only if the accredited person warrants that sufficient internal guard space has been allocated to mitigate potential interference to neighbours, or if the adjacent licensee agrees to accept interference (usually in return for payment of a commercial fee) in accordance with advisory guidelin
