This Article is doing the rounds, and technically, most of it is wrong. Somehow it's still a bit right!
- TDMA is very much still a thing; your 4G/5G phone is not emitting a continuous stream of signal, but very much bursts. But these bursts are less uniform, and at different rates, than in GSM time.
- it's not about shielding at all. It's about *susceptibility*. You don't have to shield audio (< 20 kHz) amplifers so they don't react to cellular RF (>> 1000× audio freq);
