Current Max Channel Size on 6GHz 450v 4x4 SM?

Can anyone tell me what the current maximum size of 6GHz channel I could be able to set in current firmware with a 450v 4x4 Subscriber Module in PTP mode?

Link Planner doesn’t seem to have this option available for modeling(although the ePMP 4625 is), so I’m wondering what the maximum attainable capacity on a symmetrical point-to-point link would look like.

Can anyone help?

PtP mode is currently not available on PMP450v. This feature is scheduled for an upcoming firmware release. Current maximum channel width in PtMP mode is 40MHz.

What’s the roadmap look like for larger channel sizes on the AP, or PTP mode for the SM? Do you know if there is a timeline or release date set?
I’d really like to start investing in the 6GHz (preferrable not ePMP), but the wait for these features to appear is taking a painfully long time.

I’ve seen roadmaps showing the PtP feature coming in September but this will probably be pushed out another month or two.

Channel widths up to 100MHz are planned, but it will require the deep VC queue to be optimized first. The deep VC queue optimization is also supposed to come in September, but again, I think this will be pushed out. Once deep VC queue is optimized, this will provide the foundation for them to start working on larger channel widths. I believe 80MHz will come first, followed up by 100MHz. To give you an idea of the development pace, earlier road maps showed 80MHz was supposed to be delivered in R24.2 in August of this year… well, that obviously didn’t happen. Firmware release R24.1 is still currently in beta… but I think it’s close to being released.

If your goal is to just use 6GHz for PtP use, then I think ePMP will work quite well depending on your goals. The PtP mode of the e4k radio is quite mature at this point and many operators are using it with success. Being able to use SFP+ ports and connectorized radios w/RFE ultradishes is very handy. We have a short e4k 6GHz PtP link that’s able to achieve 4096QAM and use a 160MHz channel width that can achieve just over 2gbps of TCP throughput.

What antenna was your go to?

Like I said, RFE ultradishes

Oh my word, I am blind, thank you… for your 6ghz ptmp do you use cambium or RFE sector antenna?

For the 4600 4x4 we use Cambium’s OEM antenna. For the 4600L, we use RFE horns.

Awesome, appreciate it.

What is the links distance?

242 meters LOS in an urban environment bridging two buildings.
