Cable plants are generally weak on upstream bandwidth. Around here, there's only 4x 6mhz channels allocated for upstream, meaning about 100 megabits is shared across an entire node, which is 100's of homes. Downstream, on the other hand, is 32+ channels, plus a DOCSIS 3.1 OFDM channel, providing over a gigabit of bandwidth (shared.)
DOCSIS 3.1 was supposed to also improve the upstream situation, but OFDM upstream is no where to be found yet, as supposedly they have to upgrade all the amplifiers to support more bandwidth in that direction. Most people don't care. They're not uploading tons of files.
I'm hoping to get fiber someday.
- naveen99 5y agoWhy can’t they just allocate more channels to upload. charge more, allocate more. But no, you can’t pay them to give you more upload.
- icedchai 5y agoThey can do it but it requires physical upgrades, swapping out every amplifier in a node, for example. It’s a slow process. Some cable systems have gone to 8 upstream channels. I don’t know of anyone who has a 3.1 OFDM upstream. Does anyone here have that?
