what is carrear aggregation

 Carrier aggregation is probably the most important thing that's happening in mobile right now.

And the way to think about carrier aggregation is this. 

 If, let's say this tower serving 

you is like a beer tap, right, and the glass 

is a smartphone and beer being poured into 

a smartphone is a movie that you're trying 

to download, okay. 

If I, you know, fill the glass from the beer 

tap, then it will take a certain amount of time .

But if I were to fill it from two beer 

taps simultaneously, then I, you know, the 

beer would, you know, fill the glass in half

the time.

And that's basically what we're doing. Instead

of providing the phone with just one LTE connection,

the tower actually connects to the phone using

two LTE connections or even three LTE connections

at the same time.

Carrier aggregation is kind of the latest

way that we have figured out how to really

boost the capacity of the network, and once

we do that, you know, then the users can experience

much higher speeds.

So could you be doubling your speed or even

tripling your speed. And that's amazing.

Let's say I have a big file that's stored

in cloud storage, right, that I need to download

to my phone, well now I can download it in

literally a fraction of the time, right, in

half the time or a third of the time.

Download speeds that are faster, upload speeds

that are faster, you know, high resolution

videos that can stream without buffering,

etc.

So solving for capacity is kind of like the

quest, the ultimate quest for everything that

we do with mobile networks.

Honestly, the best way to describe how it

works, if you dive deep into it, it's black

magic.

I mean it's amazing that we can take two connections

that exist in physical space completely separately

and combine them in the phone in such a way

that they can be treated as one much bigger,

much faster connection, and that's exactly

what carrier aggregation does.
