Comcast XFINITY → Next Gen upload speeds - Any idea when this will come to NJ?

Regarding the Xfinity 'Next Gen' (Mid Split?) network (»www.xfinity.com/network) with higher upload speeds:

1) It seems like Xfinity now supports COAM (customer owned modems) for next gen upload speeds? Let me know if am wrong? »assets.xfinity.com/asset ··· ices.pdf

2) Does anyone have an approximate idea when these speeds will be available in NJ?

PS: I believe DOCSIS 4.0 modems are still far away, so the best option for right now might be one the DOCSIS 3.1 modems which supports the higher upload speeds?

That said, if it will be a while before NJ gets the higher upload speeds, I may as well wait before buying a new modem...

(Unfortunately my current workhorse Arris S33 does not support the higher upload speeds).

Your S33 doesnt support higher upload speeds? I can get 100Mbit upload on mine fine and I THINK it can do a few hundred mbit upload without the midsplit requirement
S33 should also support mid-split fine if they would push the update out for it, the device is capable of it.. they have been "testing" it for a year now with the S33

100Mbps is about the useable capacity of 4 QAM upstream channels between 5-45Mhz. For higher capacity, they have to switch it to OFDMA or use spectrum above 45Mhz.They have been field testing the S33 with LLD.

does docsis (LLD) have anything to do with the higher upload speeds that people are waiting for their modem or is it different?

it’s different.
Follow the link I posted, that explains it.

Different, but indirectly related, as LLD with Comcast is only available where DAA/OFDMA is implemented, which is where the mid-split higher upload speeds are also available (or at least *may* be available).

there's also mid split tests for the S33

Mid split is Only available in small parts of NJ to my knowledge, it's expanding but slowly. The main spot I knew about, was certain neighborhoods in Mount Laurel, now it also looks certain Neighborhoods in Deptford and Lindenwold now too.

Thanks. Yes, the S33 supports it as you noted. Hard to believe they support it on the Hitron Coda 56 but not the S33, which many of us bought, at the time (a few years ago), to prepare us for next gen speeds.

So they really are testing it? Some replied in another thread, that they doubt the S33 will be supported (seems they want you to have to buy an S34 - the poster mentioned the S34).
I am debating getting a Hitron Coda 56, but if Xfinity will support next gen speeds on the S33 I will hold off on switching to the Hitron.

Thanks for the helpful reply. Where did you get the info (from posts here?). Just wondering where I can check.
Wish I knew approximately how long it will take for mid-split to be deployed / implemented.

Comcast has internal estimates for most locations, but they do not share to the public as those dates are highly likely to get shifted as time goes on (especially as the dates are further out the likelihood of meeting that date goes down dramatically (everyone knows that experience), and Comcast does not want the bad press of offering a date and then missing it).

One thing to be aware of is that due to the specifics of the location one can end up being an island in deployment (early, or late). If you look at the FCC maps in locations of mixed availability you will occasionally see a red area in the middle of a sea of green (or green in the middle of red). There is no way to know if you are on one of those future islands, nor what color you will be.

Comcast still states a target of 50% mid-split deployments will be complete by the end of 2024, and mostly complete by end of 2025.

For everyone still waiting, all one can do is continue to wait, and hope to soon receive one of those extended outage notifications that mention outages in the middle of the day (while not all the needed upgrades seem to happen in the middle of the day, that seems to be a common thing to happen, as there needs to be a coordination between many parts of the Comcast organization).

Thanks a lot!
As of now Status shows "Not Served".

Thanks! Appreciate all the info.
Yes, will have to just wait (patiently, hopefully).

Keep in mind, the FCC map is an after the fact compilation of data submitted by the ISP's.

It is a good reference to note progress or lack thereof in specific areas.
