Reliance Jio Fiber upload speeds are 10% of your plan speed

[varkey]

What % of their user base would really care about the upload speed?

If they can fit more users by allocating more bandwidth for downstream, then that's a win for them. The number of users who'd opt for another ISP cause of the low upload speed is way way less as compared to the savings they'd get by allocating more capacity for downstream and having more users on the same shared fiber medium. So they'd gladly tell the users looking for symmetric speeds to opt for another ISP. They simply don't want that kind of user base.

So from what I understood after reading the link (not 100% sure) is that it works like this.
E.g. Take a fiber which is rated for 1gbit full duplex communication. You can split it is 90:10 by allocating 1.8 gbit for down and 0.2 gbit up.
On this ratio you can put atleast 18: 100 down 10 up users (assuming contention of 1:1). Whereas on a 1gig up and down line. You can only put 10 people with 100 down and 10 up connection before it chokes up (again assuming 1:1 contention)

Hence you will end up saving lots of money on laying cables.

I would suggest you to first understand how fiber internet works. A single strand of fiber can carry multiple wavelength and each wavelength is cable of carrying several hundred gigabit of data simultaneously.

Yes the example was just a really toned down version. You can scale it up to multi gigabit fibers also.

Will still read up more on it.

 

[mikrotik]

It doesn't make sense. Study how they have distributed their fiber. National fiber - > city fiber - >area fiber-> individual homes. Most of the traffic that is routed through their cached servers goes on separate wavelength.
I would still say capacity is not an issue. It is the idiot decision making and high head headedness. I have tried complaining at the top most level through govt but since govt is blind towards any wrong doings of Jio they are pulling it off. Their TnC doesn't mention this upload speed.

I think this is applicable only on cable internet eg.Docsis when there are only fixed number of channels available eg. 512, so providers usually bond more channels for downstream than upstream.

Whereas in fiber, the transceiver uses different wavelength for downstream and upstream. So the capacity of the fiber may not be the bottleneck in this case.

Also a 1Gigabit port can send and receive 1Gbps on both directions. But it can't send more than 1Gbps on a single direction.

@mikrotik that's exactly my question is. It doesn't make any sense to cap upload speeds like that, why do they even do it is beyond me. till now, the only explanation that sounds reasonable is that they don't want it used for commercial use, even that isn't too convincing honestly.

if they were gaining anything by doing this, I'm sure atleast some ISP would've tried it before, especially the local ones. but at the same time, it's hard to believe Reliance will do this stupid thing if it didn't benefit them in some way.

 

[mikrotik]

They are using cg-nat to render this not usable for commercial use. And on top of that poor routing.

 

[royalroy]

@achaudhary997 that doesn’t make any sense. Yes, the second argument is more likely, they don’t want people to be hosting servers and such, and want to protect their enterprise broadband business.

They have already blocked all ports and used CG-NAT to break all possibilities of hosting a server. So, that is not the reason actually.

 

[philip]

Well if it was coming from a local isp we can understand the capping but since its coming jio thats the thing not conivncing since they have lots of backend bandwidth and fiber backbone ,international gateways and what not. If it was 100:50 it still good but 100:10 is the one thats just stupid.

 

[Gaurav15]

@philip Exactly. 50% is fine, 10% is too damn low.
