Wireless Networks

Mobile and wireless communications networks use radio signals to provide a range of voice, video and other data services to subscribers. The radio signals are transmitted between the fixed radio transmitters and mobile devices.

As both the radio transmitters and mobile devices are low powered and the available frequencies limited, a network of antenna sites is used to provide service in a geographic area. As subscribers increase, as well as for services at higher data rates and at higher radio transmitter frequencies, additional antenna sites are required and the area serviced by the antennas becomes smaller.

Some people are concerned about possible health risks of long-term exposure to these low-level radio signals.

Wireless networks are designed to comply with international safety guidelines, which the WHO states provide protection against all known health hazards.
