On: DSP Inside TI Radar Puts AI on Edge

They are adequately shielded, but also have 1 kW resonating inside. They have enough to meet the OSHA standard of 1 mW/cm^2.

The chip in question only emits 20 mW, and coupled into a 10 dB gain antenna, the EIRP is still only a few 100 mW. Now spread that over a few 1000 cm^2, and it’s not much at all.

For a fun experiment, put your phone in a microwave. Notice the WiFi bars go to zero, but the cellular bars don’t change (much).

As long as you don't turn on the oven. Then the phone goes "bzzzzt-POP!" and lets the magic smoke out. :)
