Xfinity UPLOAD SPEEDS

Why does Xfinity have such terrible upload speeds?  Their download speeds are great but why are their upload speeds so far off?  The 400 mbps triple play package only has 10-12 mbps upload speed.. why ?  I don't want to pay 300 dollars a month to get a decent upload ...

It is DOCSIS limitations through the upstream spectrum. But don't worry, Full Duplex DOCSIS is on the way, but don't know how long for implementation.

At 10 Mbps it not a physical DOCSIS limitation thing. It's a corporate choice.

 

A current single 64 QAM modulated, 6.4MHz-wide, 5.120 MSym/sec upstream channel supports a raw data rate of approximately 30.72 Mbps and a real world throughput of approximately 27 Mbps.

Was referring to upload in DOCSIS in general.
