In August, Motorola announced it could still be the world's first genuine 5G phone – the exclusive version of Verizon's Moto Z3 with 5G Moto Mod. This is a snap-on module that the company promises to give you a madly fast 5Gbps cellular connection faster than most phone lines these days. But buyers of the Moto Z3 had to take the word for the company because the 5G Mod would not be available until "early 2019" when Verizon's 5G NR network was to be released in the US.
Well, 5G Moto Modd just crossed the FCC today and came in surprise ̵
And one of these details will surely surprise you. some people, even if this is not necessarily something that someone has to worry about. Namely, the 5G Moto Mod will include proximity sensors that turn off any of its 4mm 5G antennas if your fingers get too close.
Here is part of the Motorola description: proximity sensors are used to deactivate the transmission from a given antenna array mm when the user can be located in the immediate vicinity of the module and in the direction the module can transmit. The control mechanism is simple in which if the proximity sensors indicate the potential presence of the user within a rough cone area in front of the module where the power density may reach the MPE limit, this module is disconnected from the modem. This stops and prevents the transmission from the module in question until the condition is cleared
Before you respond to this, a few things you need to know:
- Millimeter wave propagation is considered non-ionizing – not enough
- Probably already you have experienced radiation with millimeter waves if you have passed an airport scanner. The FDA says that this type of dose has no "known harmful effects on health".
- The FCC already has exposure limits in millimeter waves, and that's what the Motorola system meets.
- Motorola continues to say that proximity sensors are not the only way to disable these antennas – Mod also automatically selects an antenna with better signal strength if your fingers block others.
But it is quite interesting that Motorola feels the need to include such a system, and I'm curious if other 5G devices will also have one.
Previously, we learned that the 5G Moto Mod contains virtually all high-end internal smartphones, including its own Snapdragon 855 processor, X50 5G modem, 10 antennas and its own 2000 mAh battery. You need to drain your connected phone, but the FCC submission also reveals a less exciting specification: The mod looks 7 mm thick at its thickest point, which means it will double the thickness of your 6.75 mm Moto Z3 phone.
