Pager Power are undertaking an increasing number of TETRA radio impact assessments. 

TETRA is a digital radio system normally used for communications to emergency service vehicles and personnel. In the UK the system is called Airwave. Wind Turbines reflect and block radio signals which can adversely affect the performance of radio systems. 

System operators can raise objections in situations where analysis shows that there is unlikely to be radio coverage, or where there is coverage from alternative transmitters which the wind farm will not affect. 

Pager Power has custom software that predicts areas of wind farm interference.
