5G telecommunication networks will employ low-(0.6 GHz - 3.7 GHz), mid-(3.7 – 24 GHz), and high-band frequencies (24 GHz and higher). The “high-band” frequencies largely consist of millimeter waves, a type of electromagnetic radiation with wavelengths within 1- 10 millimeters and frequencies ranging from 30 to 300 GHz. For comparison, the 2G, 3G and 4G mobile services employ much lower frequencies between 0.8 GHz and 2.6 GHz.
There is a massive push by governments and telecommunication companies to fast track the rollout of fifth generation technology. Unlike 4G, the new technology promises superfast downloads and greater accessibilty, a fully interconnected world promising a better standard of life, driverless cars, the Internet of Things (IoT) mass data gathering and Smart Cities. There are also almost unprecedented levels of profit to be made but how do we know that this new technology is safe?
