Replacement guidance on this page is quoted from Cambium Networks's official end-of-life bulletin (linked above). EOSL.ai sells no hardware and lists no paid placements — this is the manufacturer's stated path, and third-party maintenance past the cutoff is also an option.

Migration questions

What is the replacement for the Cambium Networks N500?

Cambium Networks's end-of-life bulletin names N550 as the recommended migration path for the Cambium Networks N500. The exact wording and any per-part-number mapping are in the linked bulletin.

Is the Cambium Networks N500 end of life?

Cambium Networks support for the Cambium Networks N500 ended Sep 2025 — unsupported units need a plan. Full lifecycle dates by part number: https://eosl.ai/system/cambium-n500/.

Is there a per-part-number replacement mapping for the N500?

Yes — the bulletin maps replacements at the part-number level for 47 SKUs (for example NB-N500910B-US → N550). The full table is on this page.

Do I have to buy the Cambium Networks-recommended replacement?

No. The bulletin's named successor is Cambium Networks's suggested path, not an obligation. Teams also keep N500 units running under third-party maintenance after the support cutoff, migrate to a different vendor, or run low-criticality units to failure with the risk documented. See the support-options guide for the trade-offs.
