Upstream channel bonding: Any plans to bond more than 2?
Are there any plans for more than 2 upstream channels to be bonded? Reason I ask is that I've noticed there are 4 upstream channels available in this area, although only 2x16QAM being bonded at any given time. These being:
25.8 MHz 32.6 MHz 39.4 MHz 46.2 MHz I'm guessing that it's not going to be needed until upload speeds go higher? Although I think I remember 3 upstream channels being bonded when the WiFi sharing was originally released. Is that happening with the re-release of the WiFi sharing? |

With how bad Virgins upload speeds are I doubt they have any need.

About 18 months ago, some people did get a 3rd channel bonded (And possibly a few with 4?), around the time of the "first" Wi-fi rollout before they packed it in. However, it reverted back to just 2 when the rollout was cancelled.

there were two things going on at the time. They were rolling out a third channel for the public wifi sharing and at the same time there were working on the modulation to try and squeeze more bandwidth out of each channel as they were also in the process of rolling out some new tiers with higher upstream speeds. Although we all went back down to 2 channels afaik everyone should have been on QAM64 (and nit 16) shortly afterwards (which makes it a long time ago).

As in you can get 250 with 30 in America and I know in some other country's the upload is far higher for what you get is my point.

I got some weird modulation for my upstream channels.

Re: Upstream channel bonding: Any plans to bond more than 2?
They should both be 64QAM, 32QAM is a fallback. The system will try to get the best modulation it can but if it encounters noise, it drops back - more reliable, but less bandwidth.
64QAM > 32QAM > 16QAM -> QPSK I imagine if you reboot, it'll probably fix itself - but if you're not getting any errors, don't fret over it. |

I thought everyone had been on qam64 for a long time. For a while i was on one qam64 and one qam16 but like i said, i am sure both of mine have been 64 for the best part of a year. You wouldnt think so when i post screen dumps to help people out because i repost ones i made about 3 years ago which is why i did anew one for this thread.
I am hoping that in November they'll announce 500mbits on docsis3.1 to start rolling out next year. |

it is a shame Igni isn't around to provide more info, I haven't seen him in ages.

I've been on 4 upstream channels for nearly a year. 3 are on 64QAM and one still on 16QAM. VM were intending that customers should have upstream at 10% of downstream. To do that, they would need to add upstream capacity, hence 4 channels. But I'm still on 200/12 so I don't know where VM are with that.
Incidentally, if one channel is on 16QAM then that will drag the overall upstream capacity down. 16QAM has 4 bits per symbol & 64QAM has 6 bits per symbol. But because a data packet is split across all the upstream channels, it can only be reassembled at the bit density rate of the slowest channel. |
