Symmetrical Internet Speeds?

I have 1GB download , but only 20 Meg upload. This upload speed is unacceptable in today's modern connected home. A home security system with 5 cameras gets choked out by such a low upload speeds. I don't need 1GB upload, but 20 is sad...

When is Comcast going to increase their upload speeds?

The current upstream / return path bandwidth spectrum allocation on DOCSIS is physically limited. It's the current nature of the beast. This is why there isn't as much flexibility in offering faster upload speeds compared to the download. 


Here  are informative articles about the future of the upstream bandwidth capability for DOCSIS based systems;

They do offer a 3 gigabit (with symmetrical speeds) FTTH (Fiber To The Home) service in some areas. It's named "Gigabit Pro".

What is the fastest upload available over their normal coax? Residential of course. 

Also, thank you for explaining.

Currently it's 35 Mbps upload (around 42 with their 20% speed overprovisioning) with the Gigabit speed tier.
