New Zealand's RSM report that recent investigations of interference to the MetService weather radars, causing apparently permanent rain belts to show on the display, indicate most problems are arising from wireless networking service equipment in the 5.6GHz band.
The Radiocommunications Regulations (General User Radio Licence for Short Range Devices) Notice provides for use of wireless networking in the 5.470GHz to 5.725GHz band (which includes the C-band radar systems) with special conditions required to minimise the possibility of interference to radar services.
Interference investigations and auditing shows that some equipment users are not paying attention to those conditions and not ensuring compliance.
As radar services in this band provide important information in regard to weather and atmospheric conditions (including wind shear at airports) it is essential that they can operate without interference. Users of non-compliant wireless networking equipment may expect attention from RSM Radio Inspectors.
