Previous Business Updates have mentioned problems arising from WiFi installations affecting the NZ Meteorological Service rain radar. A recent investigation of issues affecting the Wellington radar showed that the problems are not restricted to land-based WiFi systems. In this instance the source was determined to be equipment operating on a vessel voyaging in the Cook Strait.
Installations of marine-based WiFi services are becoming more common (and more complex). Installers and users should be aware that the requirements applying to land-based services also apply to vessels in New Zealand waters, and should take care to prevent interference.
