Hi, as I understand it - that's just in the Beta software. Once the firmware is release, it'll have (AFAIK) all the modes we are used to on the other products. And it will also be a client which can connect to ePMP1000/2000 Access Points, as well as the yet to be finished 3000 Access Point. So - not to worry, I think this was just the first mode completed and people (like me) were asking to get them so we could start testing/using them as backhauls. :)
When the first ePMP radios came out there was no ePTP mode... it actually took awhile for this mode to be developed and operates on a completely different method of communication then the other modes. For various reasons I can see this mode being developed later because it's less used then other modes, like TDD or TDD-PTP, both of which support GPS sync and need to support backwards compatibility. The 300 (and the AC series in general) uses a completely different wifi chipset and I'm guessing that they'll have to do some serious work at a very low level to impliment ePTP. It's not just as simple as copying firmware over as ePTP relies on some low level chip magic.
Yes, Eric is correct. It’s not a straight port of the code for ePTP mode from the 11n chip to the 11ac chip. However this time around it should be quicker as we know the general idea/design to implement it successfully. Therefore we anticipate it to not take as long as the first ePMP radios. We are fully aware that ePTP mode is attractive and much sought after for PTP links for it’s low latency. We hope to roll in some of the missing features as soon as we complete development of the base functionality on the 11ac devices.
Yes, there are some features still missing - but we're using a Force300 backhaul link with pretty impressive results, even with incomplete software. We're pretty pleased with their performance and stability and spectral efficiency.
