MIMO

You watch the interview.

Look, did Mimo just ...

He did that on ...

Who? He did it on your channel?

Oh, shit, Yella.

Mimo just did that about me on your shit.

Come on, man.

Yeah.

That's not in this specific report, but at the Qualcomm thing, they were doing 7 gigahertz and 13.

And the goal is to basically have these massive MIMO.

I want them to call it supermassive MIMO.

Qualcomm calls it giga MIMO.

Somebody else calls it, I think we talked about it, different MIMO.

kind of type of extra ultra MIMO.

The more MIMO antennas they can get, so they can beam form better and perform in C band like coverage.

So they don't have to densify the networks.

i don't know it's like a newer netgear a newer ubiquity something like that and put that in place of your like your home wi-fi router um if you have or your isps rather if you have to use your isp literally i did this back in my house when i was in georgia like at t required us to use at t router which by the way like gave them access to my house i would literally like get notifications when my internet went down they're like oh yeah we had a hard time getting into your router to do maintenance and i'm like i don't like that at all so you can do is put a router behind it and some kind of firewalling where you can basically block all the traffic that the IP address of the outer router has from going into your house for sure.

There's still the question of RF, right? If you're really nitty-gritty, you can take that bitch apart and, like, ground the antennas, right? Or, like, at least put some kind of, like, metal shielding around it so, like, at least the MIMO, the RF protocol or, I guess, like, spec that they use to do this gets interfered with.

There are ways to get around this.

My large complaint is that, like...

Section 10

talks about cell-free massive MIMO.

MIMO, it's an acronym that means multiple input, multiple

output.

See if I got the album.

User-centric.

Access points.

Network MIMO.

bands but you pay for that um generally six gigahertz um in the mid-range consumer market is a compromise and the problem with it is although it does support higher speeds in general it has visibly worse penetration and so you'll you'll only get good speeds if you're in the same room or maybe one room away from the router um and otherwise it will the performance will drop off very sharply and you're actually better off normally on a five gigahertz network So I'm not I'm not digging it for not having six gigahertz, especially because now this is the interesting thing.

It's got most Wi-Fi seven routers either use two by two MIMO or four by four MIMO.

MIMO, of course, meaning multiple in multiple outs, which is where you have MIMO.

a pair of multiple antennae and transmitters and receivers, which connect at once and do parallel data streams to multiply up the amount of information that can be exchanged between the router and the clients.

If you have a 4x4 router, then...

And you still get a benefit from a 4x4 router, even if you're connecting from a 2x2 client.

What this router does, which I've never seen before, is it actually adds a fifth radio chain as well.

It doesn't implement 5x5 MIMO, though it could, but it just has that extra transmitter and antenna assembly, which gives it an improved ability to... to kind of to shore up the signal, to do even better, you know, parallelism, error correction, stuff like that.

Like New York City or Boston or San Francisco or LA, uh, or Dallas.

Those are the cities that have massive MIMO primarily-

Yeah

... which is where you want, you're going to want to deploy this.

Yeah

...

in that massive MIMO only constitutes roughly 20 to 25% of the total network over there.

So the rest of it is just macro radios where you may not necessarily need to deploy, uh, unless you're doing it for energy, in which case you care about every site because it all adds up for you as operational expenses as an operator.

Um, but again, like all of these things, how to spec it is so dependent on what the client experience is going to be.

Um, and then it starts getting into other things such as, like, are they, like the MIMO that we discussed previously, which is-

Mm-hmm

...

the, the number of spatial streams.

Do you want two by two? Do you want three by three? Do you want four by four? And this is important based on the density of the deployment, i.e., how many clients are going to be c- be connecting to a single access point at, at, at the same time, so concurrent connections.

And so if I've got a higher MIMO count, like, uh, like four by four-

Yeah
