Cambium Network Rescue · Ownership Map
Updated 2026-10-11 · Every row is dated and sourced.
Cambium Networks did not sell as one company. Airspan bought the fixed-wireless and defense lines on 2026-09-22. ePMP, enterprise Wi-Fi, cnMatrix and NSE stayed with Cambium Networks Ltd, which is in UK administration, and a bid for those remaining assets has not closed. PTP 820/850 licensed microwave has no new owner yet. This page is the product-by-product map: who owns it, what its status is, and who to call about support.
Ambio Edge Networks is an independent network engineering firm. We are not affiliated with, authorized by, or a partner of Cambium Networks, Airspan Networks, Univastu or the administrators (RSM UK). Product names are trademarks of their owners, used only to identify the equipment we work on.

The product map
“Owner” means who holds the product line on 2026-10-11 according to the filings and the Airspan FAQ. Your own warranty or support contract may say something narrower, so check it.

Running a mix? Airspan’s FAQ says that for an account holding both Airspan and ePMP or Enterprise devices it “can only commit to supporting the products that have been acquired by Airspan.” Cambium’s migration guidance (thread 108849) recommends moving only Enterprise devices to an on-premises server, and putting Fixed Wireless devices on a separate one if you move them too. Our cnMaestro Cloud after October 31 options guide walks through the choices.
The deals, sourced
Cambium Networks Ltd (in administration), the administrators and Airspan Communications Limited signed a Business Sale Agreement on 2026-09-22 for “the defense business and certain fixed broadband product lines.” Cambium Networks, Inc. transferred the related US assets at the same time. The sale completed on signing, with no closing conditions (8-K filed 2026-09-28).
US$27.5M in cash, plus 50% of net collections on the transferred receivables, capped at US$7.5M, less agreed costs (8-K). More than 135 staff moved to Airspan, and integration is expected to take about six months (Light Reading, 2026-09-22).
Cambium kept the cnMaestro software and granted Airspan a licence to it, alongside a transitional services agreement (8-K). Airspan’s product list names “cnMaestroX – FWB” under software and services.
The 8-K says the proceeds go to repaying Cambium’s secured credit facility with Bank of America, which is larger than the sale price, and that no proceeds are expected for unsecured creditors or shareholders. Questions about claims go to the administrators at [email protected]; we don’t give creditor advice.
The remaining assets
Univastu India Ltd told the National Stock Exchange of India on 2026-09-30 that its board approved acquiring assets of Cambium Networks Ltd (in administration) through a new subsidiary, Univastu UK Ltd (in formation). The stated cost is US$5.1M. Univastu entered an exclusivity agreement with the joint administrators and authorized a US$300,000 non-refundable deposit.
No asset list has been published. An email from the administrators, posted by an operator in Cambium Community thread 108849 (2026-10-06), describes “a period of strict exclusivity” for “a sale of the remaining assets” and names no products. Until a sale completes, ePMP, Wi-Fi, cnMatrix and NSE belong to a company in administration.
Before the collapse
Cambium’s published lifecycle policy promised at least 180 days’ notice of the last order date for fixed-wireless products and 90 days for enterprise products (90 days for both when a comparable replacement exists). Technical support was to run at least 4 years after end of sale for fixed wireless and 5 years for enterprise. Standard hardware warranty is 1 year from first end-user purchase, not transferable, and extendable to 5 years.
| Model | End of sale | End of support |
|---|---|---|
| ePMP 1000 5 GHz connectorized radio | 2020-02-05 | 2025-02-05 (passed) |
| ePMP 2000 5 GHz AP and AP Lite | 2022-05-13 | 2026-09-30 (passed) |
| cnMatrix EX1010, EX2010, EX2052, TX2028RF-P | 2025-12-31 | 2030-12-31 |
Source: cambiumnetworks.com/support/product-lifecycle/ and /support/warranty/, read 2026-10-11. These are promises made by a company now in administration. Whether Cambium, the administrators or any buyer will honour end-of-support dates that run past 2026 is unknown. Plan as if they might not.
What to expect next
Airspan says it moves its lines to a new support system by the end of October, with details by mid-October. The LINKPlanner profile service may shut down as early as 2026-10-31. Cambium’s cnMaestro Cloud commitment runs “through at least October 2026”; nothing has been promised past that for Enterprise devices.
UK administrators must send their proposals within 8 weeks of appointment, which puts the statutory deadline around 2026-11-09 for an appointment on 2026-09-14. The court or creditors can extend it. Filings appear on Companies House under company 07752773.
If the Univastu sale completes, the owner column for ePMP, Wi-Fi, cnMatrix and NSE changes. If it does not, those lines stay with a company the 8-K says is expected to move from administration into liquidation.
Airspan says it will announce the outcome of its talks with the OEM supplier when there is one. Until then, PTP 820/850 owners have best-effort support only.
We update this page when one of these changes. The day-by-day record lives on the Cambium Networks administration timeline.
Where we fit
Most estates sit in two or three rows at once. A Network Risk Assessment, from $3,500 (one site, up to three switch groups (a stack counts as one), 100 connected devices and 6 access points; larger estates and WISP networks priced by size on our assessment pricing page), sorts your inventory by owner and support path and gives you a written plan per product line. Our work is network-side: controllers, configuration, VLANs, routing, DHCP, SNMP, firewalls and Wi-Fi. We don’t do RF path planning, tower work, licences, RMAs or warranty claims.

FAQ
Nobody bought the whole company. On 2026-09-22 Airspan bought the defense business and certain fixed broadband lines: PMP 450, PTP 670/450i/450V, PTP 700, cnWave 60 and 28 GHz, cnReach, LINKPlanner and cnHeat, plus a licence to the cnMaestro software, which Cambium kept. The remaining assets are in exclusivity with Univastu since 2026-09-30, and that deal has not closed.
No. Airspan’s FAQ says ePMP and the Enterprise products (Wi-Fi, cnMatrix) “were not acquired by Airspan” and tells owners to contact Cambium Networks.
Univastu India’s board approved a US$5.1M acquisition of assets of Cambium Networks Ltd (in administration) through Univastu UK Ltd (in formation), entered exclusivity with the administrators and authorized a US$300,000 non-refundable deposit (NSE filing, 2026-09-30). No asset list has been published, and the sale has not closed as of 2026-10-11.
Older models are. Cambium’s lifecycle page shows the ePMP 1000 5 GHz radios end-of-sale 2020-02-05 and the ePMP 2000 APs end-of-sale 2022-05-13 with support ending 2026-09-30. For current ePMP, there is no buyer and no published roadmap. Installed radios keep passing traffic; what is uncertain is support, firmware and management.
For the lines Airspan bought, its FAQ says they stay supported in cnMaestro cloud and on-premises, X and Essentials, and “there is no plan to discontinue cnMaestro.” Cambium kept the software and licensed it to Airspan. For Wi-Fi, cnMatrix and NSE, Cambium says the cloud “may not support Enterprise devices post the end of October, 2026.” If one account holds both, Airspan says it can only commit to its own products.
Nobody has taken them on yet. Airspan says the PTP 820/850 products are not on its transfer list, that it is in discussions with the OEM supplier, and that it gives best-effort support through the existing channels until that is resolved.
cnMatrix was not acquired by Airspan, so support stays with Cambium Networks while it is in administration. Before the collapse, Cambium published end-of-support 2030-12-31 for the EX1010, EX2010, EX2052 and TX2028RF-P. Whether any buyer honours those dates is unknown.
