AI0010: The Radios Don't Know Cambium is Shutting Down - TelePost.ai

One story this week, and it's a big one. Cambium Networks Limited filed a Notice of Intention to appoint an administrator on 10 September, and the Nasdaq delisting appeal is finished. Drew walks through what's actually documented, how a company built out of Motorola Canopy and Orthogon ended up here, and what it means for anyone with Cambium gear in the air right now.

There's a history lesson in here about GPS sync and grid dishes, a hard look at where the point-to-multipoint bench got so thin, and a practical pass through the alternatives -- plus the one question Drew thinks you should be asking every vendor you talk to from now on.

Cambium files a Notice of Intention to appoint an administrator, and the Nasdaq appeal ends. From Motorola Canopy and Orthogon to Cambium: how the crown jewel aged out. Where to go Monday morning on CBRS, point-to-point, sixty gigahertz and enterprise Wi-Fi.

Everything in this episode, in full:

• Cambium's radios will outlive the company: The last great thing they can do is open up the hardware & software.

When Equipment Outlives The Company

SPEAKER_00 0:30

Somewhere right now there's a sector on a tower doing exactly what it did yesterday. There's a backhaul link holding it five nines through weather that should have dropped it. None of that hardware knows what's going on with the company that built it. That gap between equipment that works fine and a vendor that doesn't exist anymore is the whole story this week.

Why This One Story Matters

SPEAKER_00 0:58

I'm Drew Lentz, and this is the Waves Weekly Rundown. One story this week, and it deserves the whole episode. Cambium Networks filed a notice of intention to appoint an administrator, and I want to go through what's actually documented, how a company built on Motorola Canopy and Orthagon ended up here, and what you do Monday morning if you've got their radios in the air.

What’s Documented About Administration

SPEAKER_00 1:18

Let's be precise about what we know because there's a lot of rumor flying. On tenant September 2026, Cambium Networks Limited, the England registered entity the group operates under, filed a notice of intention to appoint an administrator. IS Preview confirmed the filing independently. Once a company enters administration, it's generally shielded from creditor action, while the administrators figure out what can be sold, salvaged, or wound down. That follows a rough 18 months. Trading in the ordinary shares was suspended at the open on March 27, 2026, after the NASDAQ Hearings panel determined to delist. Cambium appealed, got current on its SEC filings in May, and on August 25th, the NASDAQ Listing and Hearing Review Council affirmed the delisting. The appeal is finished. There's chatter about pieces of the fixed wireless and point-to-multi-point business going to another group. Treat that as rumor until someone puts a name on it, and nobody has said anything at all about enterprise Wi-Fi, the controller, or the switching

From Motorola Canopy To Cambium

SPEAKER_00 2:12

line. I've spent close to 30 years in this industry, and I've put a lot of cambium in the air, so let me tell you how we got here. For anyone who built wireless internet in the early 2000s, Motorola Canopy was the moment the field became a profession. Before it, you cobbled networks together out of whatever transmitted. Surplus radios, 24-inch grid dishes, Cisco Aeronet 350s, Proxim Gear, Orinoco PCMCIA cards run through tiny pigtails into enormous antennas. You mixed and matched until a signal held, then drove back out when it didn't. Canopy arrived as one coherent program, hardware management, a repeatable install. It cost more than people were used to, and operators grumbled plenty, but almost nobody grumbled about what it did. GPS sync meant you could stack sectors on a tower or sit next to another operator without tearing each other apart. That was the unlock. That's what made point to multi-point a business instead of an experiment. The reflector dish, though, confused customers endlessly. I can't count how many times someone called convince we'd mounted their satellite dish upside down. Then 2006 brought orthogonals and point-to-point links that shouldn't have worked but did. The PTP 300, 400, 500, and 600 families promised five nines through non-line of sight, over water, across open terrain, in a market where 95% was considered respectable. You'd light a link through obstruction and multipath and not quite believe the numbers coming back. By 2011, Motorola Solutions was done. Vector Capital bought Canopy and Orthogon, and on October 27 of that year, Cambium Networks existed. Canopy became PMP, Orthogon became PTP, and the new company inherited something it hadn't created: ubiquity, cheap radios, no licensing, no recurring support fees. Cambium never solved that. It wasn't a Cambium era failure, it was the founding

The Squeeze From 5G And New Rivals

condition. What followed was a long search for higher ground. Enterprise Wi-Fi was the big bet, with Xeris coming over from Riverbed in July 2019, the same year the company went public and raised $70 million. Wispa members voted the Manufacturer of the Year for straight times. From the outside, it looked like a company arriving. And they built something genuinely ahead of the field. Cien Maestro gave operators free cloud management with no license. Nobody else at that price point was close. It was revolutionary when it shipped, and it's still doing real work today. But Enterprise never landed at scale, and the squeeze came from both directions. From below, private LTE and private 5G took the use cases that needed mobility, the handhelds, the tablets, anything that moves. Cambium's answer still meant a fixed outdoor install with a fixed antenna. From above came Tirana going straight at the installed base with throughput capacity and latency that made the comparison uncomfortable, and without the line of sight discipline everyone had accepted as the cost of doing business. Wisps, who'd run Cambium for a decade, started swapping. The quiet tragedy is in the roadmap. The strongest thing this company ever built was point-to-point, and the PTP 650 was the one. Wideband 4.9 to 6.05 GHz, 450 megabits per second, aggregate in a 45 megahertz channel, sold with a money-back guarantee that it would meet expectations. That kind of confidence gets earned, not marketed. It's end of life now, and so is its successor, the 670. Meanwhile, the investment went sideways into 60 GHz multipoint, chasing ground Toronto was already taking. TerraGraph wasn't bad technology. It was late and aimed at a problem someone else was solving faster. The crown jewel aged out while the company built the future

Monday Morning Options For WISPs

SPEAKER_00 5:40

somewhere else. So where do you go Monday morning? Here's the honest landscape. CBRS and point to multipoint is the hard one, and I won't pretend otherwise because the bench is thin. Tirana is the performance leader with the G1, and the G2 coming looks strong. After that, it gets uncomfortable. Bakesells makes good equipment at a good price, but Chinese manufacturing has drawn enough scrutiny that a lot of operators won't go near it regardless of the specs, especially anyone touching government or critical infrastructure. Telrad and back technologies are real, and BEC has customer premises equipment, but neither has much North American footprint, which means few peers who've already solved your problem. So in CBRS, you're not really choosing between alternatives, you're choosing Tirana or you're reconsidering the architecture, and reconsidering might be the actual answer. If the bench is this thin, maybe the forced upgrade is the moment to stop replacing one fixed PMP radio with another and look hard at private LTE and private 5G. Same spectrum. Standards-based gear from multiple vendors, a real ecosystem and devices that aren't bolted to a rooftop. That's an architecture with a future rather than a like-for-like swap into your next single vendor dependency.

PTP And Wi-Fi Migration Reality Check

SPEAKER_00 6:48

On point to point, consolidation had already thinned that field before any of this. Look at Saragon, which now includes Ciclu along with Aviat and Radwin. You'll pay more than you did for a 650 and you'll miss it. On 60 GHz and Teragraph, you're in better shape than you think. Radwin ships a 60 GHzmmeter wave mesh. Edgecore does Teragraph alongside Open Wi-Fi and OpenLand switching. AltaWov is out there doing something similar, though propriety. Enterprise Wi-Fi is the easy migration because Wi-Fi moves between vendors better than anything else on this list. Matching Cambium's feature per dollar is the hard part. You'll feel that in the

Lock In Risk Belongs On The Scorecard

SPEAKER_00 7:22

quote. And then there's the second question. Whatever you're evaluating, ask one more thing. What happens to me if you're next? 18 months ago that would have been dismissed as paranoid. It isn't anymore. Lock-in risk belongs on the scorecard now, right next to throughput and price. Which brings me to what I actually think should happen. Those radios are going to outlive the company. The last great thing Cambium can do is open up the hardware and the software and let the gear that's still holding 5.9s keep doing it. Here's what sticks with me. The equipment is fine, the links are up, the sectors are sweeping, the clients have no idea anything happened. It's everything behind the equipment that went away, and that's a solvable problem if the right people make one decision in the next few months.

Field Reports Wanted And Sign Off

SPEAKER_00 8:03

If you're running Cambium and you're working through this, reply and tell me what you're finding. I want to know what the real replacements look like out in the field, not on a spec sheet. I'm Drew Linz. Keep the links up.
