Wireless Safety and Health Risks (White Paper)
With outdoor wireless backhaul people get concerned because we are dealing with higher frequencies ( e.g. 5GHz, 11GHz, 18GHz, 23GHz, 60GHz, etc ) and they see wireless antennas ranging from 1ft to 8ft on a tower. People assume that higher the frequency and larger the antenna the greater the health risk. This is just not true. For example at 60GHz (used for gigabit wireless backhaul) the signal at 1 Watt cannot even penetrate the human skin. Again, outdoor wireless backahul, regulated by the FCC, typically operate at extremely low levels of output power ( <1W ).
