Cambium Networks support for the Cambium Networks PTP 850S ended Nov 2025 — unsupported units need a plan. Full lifecycle dates by part number: https://eosl.ai/system/cambium-ptp-850s/.
Is there a per-part-number replacement mapping for the PTP 850S?

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 PTP 850S 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.
