No, you're moving the goal post. A company like Comcast offering a symmetrical service is huge, regardless of what the underlying technology is capable of. They could have been offering 200 megs symmetrical with Docsis 3.0, but they didn't. They restricted customers to 11mbit uploads. This is a big deal
Except they literally couldn’t? Official documentation for 3.0 is 100 up and 1G down in a lab setting. As someone who’s actually tested that with an ISP it doesn’t work in the real world. 500/50 was what was achievable in most cases. Then 3.1 pushed the download with OFDM splits, but practical applications still couldn’t hit the 1G they got in lab environments. 3.0 was never advertised to hit 200 up and 3.1 hasn’t actually hit it in real world. 4.0 will get us closer to symmetrical max.
I will say that Comcast being the biggest ISP does likely mean they’ll reach true d4 first but to my knowledge they haven’t achieved it yet.
