The ACMA has published a guide to small cells which are already delivering 4G mobile services and are expected to play a key role in providing 5G services, particularly in highly populated areas.
The guide explains that the public can expect to see small cells on light, power and even tram poles, as well as at bus stops, railway stations and on advertising panels.
Small cells are low powered base stations that emit lower levels of emissions. Because small cells are closer to your mobile they can use lower levels of power to communicate. Also, small cells will not always run at their maximum output - shutting down when there are no active mobile users nearby, so that power output levels and EME emissions from small cells are lower than the macro cells we are used to seeing in use for 3G/4G.
