we’ve got a great deal of 320 hardware and for the most part it works well, but it needs a lot of work, I just get the feeling that they’ve lost interest in the wimax as a whole 
I was hoping for some 16m spec hardware, but after a phone conversation the other day, I was told that there isn’t a market for it??? 16m spec has some amazing speeds, (by definition almost 5x 16e speeds) and features in the spec and I’d love to see that happen,
and whats up with the 2 unused antenna interfaces in the basestations??? anyone play with them to see if they are live 
?
It looks like a lot of vendors have lost their interest in wimax and go lte. I am not sure its due to technic or its simple a hype. Cambium seem to concentrate on their 450. I see very slow progress with the 320 at the moment while it would need a lot work to be done.
This 16m speeds are like lte speeds. As modulation rates are not improved the gain comes from additional spectrum. I think uplink mimo and 20MHz channels are already defined in wimax 1.6.
There is no 802.16m cpe available and I’ve not seen any vendor claiming to make one.
The only vendor with a showcase of 16m is Samsung.
DesignArts does not announce its chips are 16m capable/upgradable. Not heard this from Gemtek, too.
Some vendors sell wimax equipment they claim to be lte upgradable. None of them claims to be 16m upgradable.
So maybe cambium does not see future in wimax and sell its equipment as it is as long it is sellable?
Ya i’ve seen the same info…
use little guys are SOL for the time being i guess, atleast with standardized technologies.
I’d love to see a FDD radio for us, but thats probably never going to happen since we get 1 lightly liscence band to work with, and the big carries get both the 700 and 800 bands.
It would be nice to get some real spectrum to work with and get to use a FDD system like LTE, until then we are SOL i guess
I was really hoping to see M happen from moto, we’ve been holding back funds to ether go passisive optics or change over to M so we can add video to our service.
the optics of course is much faster, but installing and leasing poles is extreamly costly, but in town were it would make the most since, there is already a CATV provider. I know E can carry video, but there isn’t enough bandwidth to really do it well.
I hope to see an LTE, or Wimax M product for us little guys as some point… granted i know some of us have a few thousand subs, it doesn’t compair to the millions of users on the big networks.
Hi,
Somebody known when cambium release new firmware 3.0 ??

Talking to suppliers I hear: "802.16m wont happen". But I expect getting some improvements
for 16e. E.g. I see some CPE do 2tx. I see Basestations which do 2x10MHz on one sector.
I see Basestations announced which do 3 Sectors Mimo each with 10MHz.
As prices go down and products mature may be we'll happier staying with 16e.

Don't know about "3.0", but the newest was released in the past 48 hours, 2.2.2 for AP and 8.1.4 for CPE. First versions with Cambium branding, only minor bugfixes and changes per docs, but I noticed a new (undocumented) TR-069 ACS config panel under 'Management' in the CPE...

after talking to our sales rep, 3.0 is due out end of april
also she talked to us about 3x3 mimo being possible down the road if the 320 line contiues to sell well. the basestations we have do have 2 unused antenna ports on the PCB, so the hardware is already here, just need the software… I really hope this happens! the pentration improvements would be wounderful and hopefully for the LOS customers even higher basestation capacitiy. unfortunatly this is only a maybe

Sales roadmaps have their own rules. Look at roadmaps from motorola and alvarion regarding wimax
which are 1-2 years old. Both are vaporware now. WYSIWYG.
There is not a single cpe with 3 Antennas. The 320cpe does only downlink-mimo.
You can increase coverage with beamforming or higher order rx at the basestation but you cant increase
capacity due to the limits of the cpes. First step would be to get 2x2.
SW-Development seized. We still run without security enabled as cpes get hangups. Now this bug is in the list of known
bugs but the promised fix is still not there. We're waiting for month's now to get a feature working which is promised since
the beginning. It's a joke when a sales rep promises advanced RF-Features facing this basic homework which have to be
done.
UBNT claims it's new product is developed by ex-motorola engineers. Dont know how much of these experts exist ...
320 already has 2x2 mimo, the base stations transmit on vertical and horizontal planes, and for now the CPEs are SISO, the 3.0 patch unlocks 2x2 mimo in the CPE
You do not have to have 3x3 on both ends to enjoy the penetration benefits of 3x3. Granted it will run better in that method. And since it was mentioned down the road, I would imagine that gives plenty of time to come up with a new CPE that would support 3x3
I’m with you on the frustration over some of these features not being fixed yet, and I will reiterate that the mention of 3x3 mimo was DOWN THE ROAD. The 3.0 patch from what I have been told from my sales rep will have a wizard for qos for those that have trouble understanding QoS, Ethernet stats similar to the classic canopy, a click thru proxy to get to CPEs like the classic 100 series, additional AAA support, and a memory leak problem solved (the root cause of your security problem I would assume) as well as additional bug fixes and performance improvements. The 3.0 patch is due out middle to end of april.
Wimax as a whole by all of the big manufactures has pretty we gotten sort changed, bottom line the small providers like us, who want to provide quality service for a reasonable population has suffered as the end result. I more than understand the drive to get the 450 product out the door as quickly as possible. I would love to see wimax M realized, however it doesn’t look like that’s going to happen. The mechanisms that handle the 802.16 protocols, from a programming point of view is ridiculously complicated, and largely untested. Canopy propriety mac, and alvarions version are tried and true, both are solid, both are predictable performance both have their advantages over the other. In my opinion the ubnt products will never be an honesty player in the larger networks until they have gotten away from using the cheapest atheros chips and get a chipset with quality error correction and timing control. The only reason so many startups run to them (and ultimately fail or change to another company) is the $$$s. again from the areas we serve we used to have 5 others whisps and its down to us and 1 other company. The 3 that are now dead were all ubnt providers that poor quality of network and poor customer service allowed us to buy their subscribers for next to nothing, fix up the ubnt network somewhat and replace most with canopy.
UNBT will claim anything to try and throw crap wifi against moto and alverion. It really disheartens me to see the horrible experience so many network subscribers have been put through by small wisp trying match penetration and dependability of the better wisps use quality hardware to power their networks.
We have dealt with an unbelievable amount of skepticism in new markets simply due to a different come and go operation has damaged the reputation of “wireless” network.
Unbt has its place in very light customer densities on relatively short range shots, private use and what not. In order to get to max modulation you need 35db SNR, how realistic is that??? And a relatively realist SnR for 2.4 (15 db) the best link that I have personally measured got a whopping 6.7 mbps one way.
Unbt doesn’t even support meshing protocols that employ a means of quality control over a network, any real load on the network causes ridicules packet collisions, they claim 150mb thru put, maybe signaling rate. The last little guy we bought out had some of the new GPS hardware and it was a joke, still needed guard bands to keep each other clean, didn’t do crap about CPE control, alls it did was reduce some of the nature of an over saturated cheep wifi network. In Jperf the “PTP” could only handle 15k PPS under multisession load, and was only able to support 31.6mbps one way before it began to fall apart. What ISP realistically is going to demand there tall claim of “ 150mbps” with a couple of users on the other end?

Is the cpe hw-capable doing this? As I've learned this are gemtek cpes with adapted firmware.
The menu structure looks very much the same but the adapted firmware introduced the problem
that using harq limits the cpe to <10MBit/s which should not be there in the original firmware.
I get an original gemtek soon to verify this. As I heard the original firmware does only uplink siso, too...

Every additional chain gives some additional gain. But this would need some hw/sw development.
Much more effort than fixing the bugs ...

This is out of scope. PMP320 and CPE base on foreign hw. CPE much more than AP. Doing a 3x3 wimax cpe
is something the whole wimax market is not willing to do. Seeing this from cambium would be a very big surprise.

Yes. Very far down the road. If you said 4x2 or 6x2 it would be possible as it is something that can be done
with DAN2400. But x3 is not doable with any cpe-hw I have seen so far. It would need a chipset vendor like
sequans to do this as it would need a complete new development fork for cambium going this direction.
So the sales rep which took this into his mouth is "very optimistic".

I hope this helps. As said I had a promise that "my" bug is fixed in the march release.
And at moto times I had a roadmap from sales rep which promised a lot more stuff...
So I am not only frustrated. I am annoyed.
Wireless gear is the base of my business and if someone sells me gear which does not
work as promised he does harm to me.

I only added UBNT to the discussion as they claim to have hired away some of the moto engineers
and I have the feeling there are missing some engineers at cambium to drive the PMP320 platform
further.
I do not use any UBNT stuff as testing their gear and following their mailinglists I do not want to
work with them. There is a very big difference between there promises and their gear. I followed their
GPS-Sync and 3.5GHz stuff and I see they did not get it working to a point where I would like to use
it but they are selling it for a while now.
I look at companies like moto/cambium to work with where there is true engineering done to make things
reliable working. But with PMP320 they are far away from the quality level I see with e.g. ptp600. And I
see behavior which goes in the direction of UBNT. It is sold, has basic bugs and fixes are promised for
the future. And there are sales rep which talks the next features.
Hi ste,
You have completely right !! I have problem cpe resetitself but no one help me
