A wireless transmitter uses almost no power and at first glance appears to violate the laws of physics. It’s actually a clever use of physics that could one day transmit data from tiny remote sensors.
As the wireless telecommunications companies ramp up their 5G rollouts, they are beginning to pull the plug on their 3G networks. 2022 is the end of the line for the venerable cellphone service.
The FAA raised concerns that new, full-speed 5G cellphone services near airports could interfere with aircraft operations.
