Measurement of EMF exposure around small cell base station sites

With the ever-increasing demand for data on mobile devices, network operators are looking at a range of options to increase their network capacity. One of these options is through the use of ‘small cell’ sites, an umbrella term for operator-controlled, low-powered radio access nodes.

While the radio-frequency exposure from small cells is equivalent to other low-powered equipment, there has been interest in a practical study of the devices in real world settings. For this reason, the MWF and the Small Cell Forum commissioned in 2017 a measurement program, the results of which were published in a peer-reviewed scientific journal.

The Importance of Quality Control Measures in Scientific Studies

In a paper by Vijayalaxmia and Prihodab TJ, the authors looked at the influence of four quality control measures ideally associated with studies of exposure to radio-frequency (RF) energy. In this particular analysis, they assessed 225 published papers from the period 1990-2017, involving 110 animal studies and 115 studies of human cells exposed in vitro and in vivo to RF energy (involving 2,160 actual test results) for the inclusion of four specific quality control measures. The bottom line is that the inclusion of any, some or all quality measures saw fewer reported effects – or no effects at all - associated with exposure to RF energy, highlighting the importance of these measures in quality studies and publications in this area. Our Viewpoint provides a summary of the study and details the quality control measures and their importance in  studies in this area.
