The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
The risks depend considerably on what kind of Wi-Fi network you’re using. Public Wi-Fi networks—found in airports, coffee shops, and other public spaces where you should never use public Wi ...
Network eavesdropping, also known as eavesdropping attack, sniffing attack, or snooping attack, is a method that retrieves user information through the internet.This attack happens on electronic devices like computers and smartphones.
The band is essentially undeveloped and available for use in a broad range of new products and services, including high-speed, point-to-point wireless local area networks and broadband Internet access. WirelessHD is another recent technology that operates near the 60 GHz range. Highly directional, "pencil-beam" signal characteristics permit ...
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.
As with its infrared and ultraviolet radiation dangers, welding creates an intense brightness in the visible light spectrum, which may cause temporary flash blindness. Some sources state that there is no minimum safe distance for exposure to these radiation emissions without adequate eye protection.

Firstenberg has argued in numerous publications that wireless technology is dangerous. In 1997, the Cellular Phone Taskforce was the lead petitioner in a challenge to the Federal Communications Commission's RF radiation exposure limits, which was joined by dozens of other parties including the Ad Hoc Association of Parties Concerned About the Federal Communications Commission Radio Frequency ...
