5G requires more towers, closer to their end users. To quote the article:

> 5G will require cell antennas every 100 to 200 meters, exposing many people to millimeter wave radiation. 5G also employs new technologies (e.g., active antennas capable of beam-forming; phased arrays; massive inputs and outputs, known as MIMO) which pose unique challenges for measuring exposures.

Haha, it’s not massive inputs and outputs. It’s multiple input/output antenna arrays.

No it wont require, it will be able to work on the same frequencies as 4G does.

It can use more towers at higher frequencies in really really crowded areas or industrial setups, but those work at lower power outputs, and penetrate the body less (due to higher frequencies).

Isn't more cell antennas equivalent with much lower transmission power? Especially the phone needs to use way less power, so total amount of EM for humans nearby is going to be significantly lower.

Now compare to AM/FM transmitters that cover a huge geographic area. Those can be scary. FCC allows up to 50000 W transmission power. It's required because the antennas are spaced so far apart.

Isn't the amount of radiation you receive from the towers tiny in comparison to the radiation of your phone?

My City has them or they are under permitting for "towers" (of 30 feet or so) on nearly every block. Some right next to residences, daycares, schools, offices, etc.
