Yeah, they did develop a custom chip (ASIC, if I remember correctly) for the 
LTU radios. The airfiber 5xHD PTP radio was the first product using it. They're 
decent radios, but never quite lived up to the hype. I think they original 
airfiber 5x would have performed better in most cases, except that the HD 
supported up to 100mhz channels instead of only 50mhz. I never used the PtMP 
version, but it seemed pretty mediocre from what I saw. As far as I know, 
they're still in production, but they don't really seem to be doing any 
development anymore. 


I'm not sure how involved the old Canopy team was with that project, or if they 
were even still there at that point.

Didn’t Ubiquiti go the route of developing a custom chip at the Chicago R&D 
center (the old Canopy crew) for the later airFiber models? And was this same 
silicon used for their LTU line of PMP radios? I never used LTU, is it still an 
active product? Sounds like it’s being phased out. 



It would seem that’s the tradeoff for cost reducing something like PMP450, 
turning the FPGA into customer silicon. But you lose the ability to change that 
part of the design, you can still change the firmware. 



I feel like the companies like Analog Devices and Altera have continued to 
advance the functionality in their programmable chips aimed at the Software 
Defined Radio market. Probably driven by SDR applications like 5G cellular and 
maybe satellite and military. I think when I glanced at an FCC report for a 
Tarana radio they were using silicon like that, but they may also have their 
own custom chips for some functions. And I feel like today’s 450i, 450m and 
450b radios have much more capable programmable silicon than Canopy or the 
original 430 and 450 radios.

At the time, it probably wasn't possible to hit the price point they needed to 
with 450. I'm sure the FPGA and whatever else needs to go into a 450 costs a 
lot more than the SOC in an ePMP. 



At this point, from my perspective anyway, ePMP seems positioned a lot better 
for the future than 450.

I never understood why they invented the ePMP in the first place. If they 
wanted a lower cost product just spin a lower cost version of the 450.

If true (and probably is), I don’t understand why buy the PMP450 business and 
not also pick up ePMP if it can be done for $4-$5 million. 



ePMP does not strike me as low margin product that loses money. And if someone 
else buys it, that could be a competitor and you could regret it. Better to buy 
it and figure out how to migrate the customers to 450 if you want to shut it 
down. You could also avoid some complexity selling off cloud based systems like 
cnMaestro that support both products. 



I figured if the buyer is Airspan they might consider ePMP redundant with 
Mimosa, but it looks like they no longer own Mimosa? I had low confidence in 
the EVO plan, but even if you give up on the converged platform, for that 
little money some companies would buy ePMP just to shut it down and eliminate a 
competitor. (Larry Ellison would do it. Google or Amazon would do it.) Maybe do 
the shutdown gracefully so as not to piss off PMP450 customers any more than 
has already been done. Because some WISPs use both products. Mine is basically 
a PMP450 shop but I’ve got some Force 300 at customer prem and Force 425 
backhauls. 



Maybe it’s something crazy like when Airspan sold Mimosa they agreed not to 
have any future WiFi chip based products and therefore they are legally 
prohibited from buying ePMP. That’s pretty far fetched. 



Or maybe they don’t want the products or the customers, they want the design 
team for new projects. I find it interesting to peruse LinkedIn and try to 
figure out where Tarana hired all their R&D people. Or look at what Ubiquiti 
did when they hired most of the Canopy engineers to staff their airFiber design 
center. They managed to do it without buying the company though.

I have no direct knowledge of any of this, but I have now had several people 
openly tell me the following: 

The PMP 450 product line is supposedly being purchased by Airspan, which itself 
previously went through bankruptcy and later became a privately held company. 

I have also heard that the ePMP business was being shopped for somewhere in the 
$4-$5 million range. 

None of this really makes sense to me. Cambium was still doing roughly $35-$45 
million in sales per quarter. It seems like deeper workforce reductions and the 
discontinuation of underperforming product lines should have happened much 
earlier rather than allowing the situation to deteriorate to this point. 

There is a lot of head-scratching over the whole situation because, from the 
outside, U.S. sales still appear to be largely intact. While the stock itself 
is delisted and on the non-filer expert market, it is still trading though 
worthless.

It’s a challenge trying to decipher the communication and activity or lack 
thereof from Cambium. Like they just did an ePMP firmware release, although 
maybe just to move it from RC to release status. Support is still available and 
guidance is being issued on transitioning to cnMaestro onprem. Very quiet 
regarding PMP. 



If I had to take a guess, I’d say all this indicates (1) they have a buyer 
lined up for PMP, (2) they are trying to find a buyer for ePMP and have some 
hopes that can be accomplished, and (3) the Enterprise stuff is being flushed. 
(anybody remember “getting flushed” from Men In Black?) If that’s true, it 
would be the exact reverse of what I would have expected, I would have expected 
the new switching and WiFi stuff to be hot, ePMP to be warm, and legacy 450 to 
get flushed. 



I echo what Dev says about the people there. Obviously at the top levels, 
mistakes were made (to quote Ronald Reagan). Somebody dropped the ball either 
on financial or M&A management or both. Chuck will recognize the acronym CFIT. 



But all the individuals we deal with are as Dev said, solid folks. My network 
is 450 with a smattering of ePMP and licensed PTP, so I mostly know people on 
the PMP side. The head of PMP Product Management is Matt Mangriotis, and I hope 
he stays or if not that he lands somewhere good. Maybe because I spent 20 years 
around 1980-2000 in telecom equipment engineering management, so I might have 
an old fashioned concept of what a Product Manager does, but Matt is very 
professional and well qualified, and has always responded quickly and rolled up 
his sleeves to solve problems. I’ve talked to him at trade shows, and never 
felt I was getting hype or spin. Yes, 450 had some questionable product 
direction decision over the years that didn’t work out so well or that I 
disagreed with, not sure who to blame for those. But Matt as well as all the 
support people I’ve dealt with are indeed solid folks. 



Unfortunately there’s no way this adventure doesn’t negatively impact whatever 
remains of Cambium, or that some good people don’t end up leaving because of 
the uncertainty. It’s always the best people who can easily find a job 
elsewhere. Customers and distributors may also avoid them, even under new 
ownership. I don’t know about creditors especially supply chain companies, I’m 
guessing they get burned by bankruptcies all the time.

I’m sure the remaining employees at Cambium are also waiting for a resolution 
anxiously. I’ve always had good relations with them as individuals and they 
seem like solid folks. We should wish them well and assume they’re trying to 
help. 



The corporate dynamics very likely have hard constraints placed upon them by 
other parties that they have to sort though, which will take time. I’m sure 
that they want to retain maximum value through this (regardless of where things 
land), which involves engaging customers and others as soon as they possibly 
can. This will take time, like days and weeks, not hours.
