Cambium Networks PTP 820G C000082M004A access point

SKU CH-HX62-B4C1B MPN C000082M004A

Licensed microwave backhaul radio supporting 6 to 42 GHz with dual modem and Ethernet-only connectivity

  • Licensed microwave backhaul across 6 to 42 GHz spectrum
  • Dual modem architecture enables 1+1 hot-standby redundancy
  • Split-mount and all-indoor deployment flexibility
  • Line-of-sight MIMO with 2048QAM modulation for spectral efficiency
  • High-density multi-technology nodes integrate radio and networking functions

Licensed microwave backhaul platform

The Cambium Networks PTP 820G is a point-to-point licensed microwave radio built for carrier-grade backhaul and enterprise transport. It supports licensed frequency bands from 6 to 42 GHz and integrates advanced microwave technology with high-density multi-technology nodes. The platform offers all-indoor, split-mount and all-outdoor configuration flexibility for diverse deployment scenarios. Line-of-sight MIMO and modulation up to 2048QAM deliver industry-leading throughput and spectral efficiency.

Frequency and redundancy constraints

Licensed spectrum from 6 to 42 GHz requires regulatory approval and clear line-of-sight between endpoints. The radio supports 1+0, 1+1 HSB, 2+0 and east-west configurations with 1+1 unit redundancy for high availability. Throughput scales with channel bandwidth and modulation, peaking at 2048QAM under optimal conditions. Ethernet-only interfaces limit direct legacy TDM connectivity without external adaptation.

Upgrade from single-modem or lower-band systems

Operators moving from single-modem radios or lower-frequency bands gain doubled modem capacity and access to wider 6-42 GHz spectrum. The jump is worth it when spectral efficiency must increase without new site acquisition or when 1+1 hitless protection is required for critical links. It does not suit deployments needing integrated TDM ports or unlicensed-band operation.

Questions about this item

Should I choose the single-modem or dual-modem version of the PTP 820G?

The C000082M004A is the dual-modem model, providing two radio carriers in one chassis for higher aggregate capacity and link redundancy options.

What does the 2048QAM figure mean for actual throughput on a deployed link?

2048QAM increases bits per symbol, boosting spectral efficiency so the radio delivers industry-leading throughput within the licensed channel bandwidth you select.

Which frequency bands does the 6–42 GHz range cover and what limits the usable spectrum in practice?

The platform supports licensed bands from 6 to 42 GHz; the exact band and channel width are set by your regulatory licence and the RFU you pair with the unit.
