Motorola’s 5G Moto Mod will have proximity shutoff sensors to limit exposure to millimeter waves

#News(General) [ via IoTForIndiaGroup ]

Last August, Motorola announced what might still wind up being the world’s first true 5G phone — the Verizon-exclusive Moto Z3 with an optional 5G Moto Mod. It’s a snap-on module that the company promised would give you an insanely fast 5Gbps cellular connection, faster than most landlines these days. But Moto Z3 buyers had to take the company’s word for that, because the 5G Mod wouldn’t be available until “early 2019,” when Verizon’s 5G NR network is due to launch in the United States.

Well, the 5G Moto Mod just crossed the FCC today, and it came with a surprise in tow — a document that has more details about how it’ll work than I thought the company would ever publicly reveal.
And one of those details is sure to surprise some people, even if it’s not necessarily something anyone should actually worry about. Namely, the 5G Moto Mod will feature proximity sensors that shut off any of its four millimeter wave 5G antennas if your fingers get too close.

Before you react to that, a few things you should know:
• Millimeter wave radiation is considered non-ionizing — it doesn’t have enough energy to tear apart living tissue.
• You’ve probably already encountered millimeter wave radiation if you’ve gone through an airport body scanner. The FDA says there are “no known adverse health effects” from that kind of dose.
• The FCC has millimeter wave exposure limits already, and that’s what Motorola’s system is complying with.
