These organisations include the National Radiological Protection Board (NRPB) in the UK and the International Committee on Non-Ionising Radiation Protection (ICNIRP) world-wide. The results confirmed that Airwave base stations comply with health and safety guidelines: the measured power levels were only a small fraction of the guidelines in areas accessible to the public. Some experiments conducted in the 1970s and 80s suggested that modulated radiation could have an effect on calcium exchanges in tissues of the body, particularly for amplitude modulation around 16 Hz. The contract was signed in February 2000 and the roll out of the infrastructure was completed in May 2005.
