The website 5GWiFi, set up by Irvine-based Broadcom, offers a “primer” on the new IEEE 802.11 ac or “5G” Wi Fi chip. Scroll down to the “technical details” to read about the RF spectrum and “beamforming.” Note: Be prepared when reading industry ads to be transported “kidlike” back to Superman watching days: This chip will allow people to be “on the move,” taking their devices wherever they please to form “ad-hoc” work groups. It will improve, they say, “connectivity,” opening up a whole new “freeway” with lots of driving room (“wide lanes”) for one’s data and an ability with the “beamforming” capacity to avoid “potholes,” and penetrate surfaces heretofore impermeable to Wi-Fi such as concrete:
“Many factors affect the coverage area of a network—most notably, the way a structure is built. Concrete walls, ceramic bathroom tile, and metal appliances are more difficult for Wi-Fi signals to penetrate, in contrast to wooden walls with gypsum board, which are easier to penetrate. But signals from IEEE 802.11ac networks, with beamforming and other innovations, do a much better job in penetrating all forms of building materials than do the signals from its predecessor networks. In fact, the ability of IEEE 802.11ac signals to transmit through some concrete walls is expected to help homes in India and China, where concrete is used extensively as a construction material.”
One can get so swept away reading industry ads, that it may only occur later, when one is scrubbing the kitchen sink, the window slider open even though it is a gray day and they are predicting rain, that the ability of these new chips to penetrate concrete, ceramic and metal means that along with all the “exciting” new features the new 5G WiFi chip is “offering,” it will also be disrespecting our boundaries and invading our personal spaces: the walls of our homes, the skin which separates our bodies from the air around us; and, as the IARC WHO “Working Group” wrote in its discussion of EMF’s in The Lancet Oncology , it will, in fact, “couple” with our bodies “resulting in induced electric and magnetic fields and associated currents inside tissues”; and people who want to shield from this radiation will have a lot more difficulty.
