One big reason why 5G will be DOA

[Mr. Sheep]

Two words: Rain. Fade. Most of the frequencies 5G is using are above 6 GHz, which is when rain fade occurs. If you don't know what rain fade is, basically any signal over 6 GHz loses signal strength in the rain. This is very common in satellite services. 5G is trying to be pushed as mobile and home internet. Because it's going to have rain fade I simply can't see it being used. At the very least, I think 5G home internet won't catch on. I haven't seen many people talk about rain fade in 5G so it appears that the carriers are trying to keep info about it in the bag to try and attract more customers. In my opinion, rain fade will make 5G impractical and not worth it.

Hummm, it's hard to imagine anyone wanting to spend that kind of money developing something like that to have THAT kind of problem with it?? Not saying you're wrong mind you, just that there's a lot of smart people in this world and I'd bet that they have figured some way around it before they spent a bunch of money deploying it.

Just saying.....................

Distance matters...5g will be very close to homes..installed on telephone poles

Yeah but then those local antennas will have to go to some tower far away so it will still be affected by rain fade either way

Cell site will be local..its called fixed 5g..on a telephone pole..5g phones will still use cell towers

If most of their frequency is above 6 Ghz then why are the trying to get 100 Mhz of the lower C Band range?

 

[mdram]

you forgot about lack of penetration
much of the spectrum used cant get through trees, let alone walls

maybe exterior antenna can fix part of that, so add in a a truck roll

Thats the plan..exterior antenna

[Mr. Sheep]

That's only 100 MHz though, and majority of the frequencies they're using are still above 6 GHz

Even then, the antennas still have to go somewhere so they need to go to a cell tower or some kind of central area so it will be affected by rain fade and walls, trees and the like.

What makes you so sure that 5G is supposed to be a mesh network?

I would expect that many, if not all of the antennas would be fibered leaving only the "last mile" to wireless.

I think you're reasoning using two things you know a little about and coming up with something that is science fiction.

People could put an antenna in a window for reception. No truck roll needed. Also wouldn’t they offer 5G at 600 MHz which would be better than if it wasn’t 5G?

I was told they're meshed and I just thought having wired antennas everywhere doesn't seem practical so that's why I assumed that.

Where did you learn this (links would help support your argument)?

Mesh can certainly exist, but to suggest that it must be meshed is folly.

Yup, I've got a smartphone setup as a hot spot and fastened to my bedroom window with velcro because that's where it picks up the best signal from the cell tower it's connecting to.

Actually cell phone towers tap into the same network your regular phone uses..and it also taps into the same internet network that landline uses

My workplace uses T-mobile so I'm intimately familiar with cellular hot spots that use an Internet connection -- it is the only way we can get service inside the offices.

I thought I heard a while back that the future was people’s ota antennas would not only receive but transmit signal (mesh) to get other people signals that couldn’t reach the towers directly. I’m surprised that this isn’t implemented into more devices for a company to use to have service available in many more locations.

That may have been someone's fantasy, but I suspect that it has little to no basis in reality. I reason that OTA reception antennas make for lousy transmission antennas. Further, any of them that has a conventional amp or pre-amp on them literally can't carry a signal backwards to the input side of the amp.
