World over the mobile phone use is increasing with each passing day. According to the ITU there are over 6 billion mobile phone connections all over the world and the number of users is more than 3 billion. There is little doubt that in coming years these numbers are going to increase. As newer technologies like 4G are introduced and as the world prepares itself for 5G even more mobile sites and devices will be introduced since the IoT (Internet of Things) will require more connections with each device talking to another. More devices, more coverage, more services and this will ultimately mean more radio signals in the air. A much misunderstood issue related to the growth of mobile phones is that of radio signals and their effects on human health.
