I wonder if smaller devices or implants will be used? Example, Sweden. They’re looking at being the first cashless society, via a microchip.

When this becomes widespread it's a wrap

Lowkey almost pointless for smartphones.

It'll make a huge difference in IoT though.

IoT? What’s that

Internet of Things

That's about every object around you, from the door or the street lights, up to the car or the infrastructure inside an hospital, being connected to the internet.

The main thing about 5G is that it can bring the lag between input and output down to few milliseconds, so technically in the future we could see a surgeon in Japan performing surgery in real time in the US or a commercial truck going through Spain but actually being controlled by a driver in Sweden (just a couple of stupid examples).

This will also bring a huge bunch of security and privacy issues, as I'm sure having every object in your house, street, city, being connected to the internet could easily be abused by tech companies (privacy) or by hackers (security)

crying

Whaaat????

it'll be big for people who live in high density areas

my 4G chokes hard in downtown areas (baltimore area)

True, didn't think about this. I live in a big city as well and sometimes the 4G signal is embarrassingly bad.

5G spectrum has some struggles to overcome though. From what I understand some frequencies (mmWaves) aren't the best at passing through objects such as walls, trees etc, so the solution will be to build some main cell towers (as with LTE) but then they will have to install a bunch of smaller cells around the urban area in strategical places, such as poles, manhole covers (Vodafone was testing that in the UK), to beam the 4G/5G signal.

I wouldn't be surprised to see some carriers doing a s***ty job at covering some areas, as that will require big investments, probably bigger than what 4G required imo.
