See "Mobile data: The only way is uplink" - here.
I am not sure I follow the logic, as we need to know first whether people are generally use mobile data services to upload (or do it more from their home fixed connection), and if the ratio of download:upload is less than 2:1, meaning an average of less than 2 views to each video byte uploaded. Note that other applications, totaling to 40% of the capacity (according to Bytemobile itself - here), are also generating primarily download traffic.
Back to the article - "You can't double your capacity by tossing raw bandwidth at it .. For a large operator with a subscriber base of 100 million it would cost $4 billion to add 40% capacity to the network through adding bandwidth alone, Alternatively, the same operator could spend $2 billion to add 20% capacity then put optimisation on top of that, which would leave it with a total capacity increase of 60%. The cost of optimisation would be up to $10 million"
It is not clear how Bytemobile type optimization can help carriers on the uplink, as optimization is placed on the packet core and would not help uploads. I guess Ronny means that with optimization, carriers will be able to set the capacity to a different ratio. Sounds complicated.
