Assessing Electromagnetic Radiation in our Environment

A variety of wireless networks have surrounded us for the provision of ubiquitous communication services. While the earliest communication infrastructure used wires for data exchange, wireless communication networks have become more popular over the years. Wireless communication provides freedom from wires and allows a device to communicate over a network regardless of its location. All wireless networks employ antennas that broadcast data into our environment as electromagnetic signals. With an increasing number of wireless networks, the number of elements that radiate in our ambient environment has also risen significantly. While each antenna element may broadcast at a relatively smaller transmit power, a large number of such antennas may emit considerable amount of electromagnetic energy into the environment.
