Hi all, looking for advice on everyones experience with what is stated in the subject line.  Been trying both but nothing solid using either... wondering if software is the real issue....

Thanks

If you wish to use bonding (which is the killer feature for the 550) then unfortunately you can't use ePTP mode at the same time. In order to bond, the radios need to have synchronized transmit and receive frames... and ePTP is "flexible" - so therefor it's an either/or... and not both situation.

So, if you wish to use ePTP, you are restricted to a single radio.
And if you wish to use dual radio bonding, then you are restricted to TDD.

That being said, we have some existing 550 links in place, and we are running 4.5.4 RC and we are finding performance and stability ok in TDD mode. For us, it's not bad enough to pull them out, so we will leave them in place for now. But it's also not fantastic either, and we have other PTP550's sitting in the box that I doubt we're going to deploy.

Thanks ninedd.... so are we looking at the ptp 550 tanking or hoping for next software update to rectify some things?

As mentioned, we are reasonably pleased with the performance, on our existing links. They are working pretty good, and I don't have any plans to remove or replace them. Unfortunately, when I bought the ePTP550 (and all of the 3000/300 line of AC gear) I didn't realize that there wasn't going to be an ePTP equivalent of what the ePMP1000 & 2000 have.  For me - the ePMP 2000 in ePTP mode is freaking awesome (except it's just 'N').  But ePTP mode on the AC line is a totally different (and even incompatible) animal.

Anyway - I don't think the PTP550 is ''tanking'' - the links we have up perform reasonably well in TDD mode.  But I also don't think future software updates will resolve any of the issues, and so I don't see there being a reason for us to deploy any more. Cambium and us seem to be on different wavelengths as for what is needed in a WISP, so I don't see it just as a firmware issue.
