Operators of critical radio services reminded

Recent work by Radio Spectrum Management has shown a need for good radio frequency engineering practices to be employed at ports following an investigation of interference on container-loader driver’s radio systems.

RSM traced the interference to newly-installed high-power transmitters that were causing front-end overload of the port’s radio equipment. The movement of containers is critical for efficient and safe port operations. Some ports use a wireless location system for containers using Short Range Devices authorised by a General User Radio Licence. In making the choice to use such a system, operators must take into account the shared nature of the licence and that no regulatory protection is given from the interfering effects of other radio services.
