Nokia AirScale Remote Radio Head model 473966A (AHCA), a macro-site radio unit designed for LTE (and potentially 5G evolution) deployments.
Model code: 473966A, marketed as “AHCA” (AirScale RRH 4T4R B5 160W)
Key configuration: 4 Tx & 4 Rx (4T4R) for Band 5 (850 MHz) FDD-LTE.
Typical output power: 160 W class for this 4T4R B5 unit.
Connector type: 4 × 4.3-10 RF connectors (typical for Nokia macro RRHs) in referenced tables.
Here are major functional/radio performance characteristics:
| Parameter | Value / Notes |
|---|---|
| Band supported | LTE Band 5 (≈ 850 MHz) — presumably for DL/UL ranges typical of 3GPP Band 5. |
| Output power / TX chains | 4 transmit chains; spec “4×40 W” is quoted in a table for this model (i.e., 4 Tx chains each 40 W) = 160 W nominal. |
| Receive chains | 4 receive chains (4R) per the “4T4R” designation. |
| Optical/Fronthaul interface | 2×9.8 Gb/s CPRI (or equivalent) interface is cited in the roadmap table for similar units. |
| Environmental / mechanical | IP65 (or similar outdoor protection) and typical temperature range of –40 °C to +55 °C for macro RRHs in this class. “5G ready HW” target. |
| Connectors / mounting | 4.3-10 RF connectors; mounting options include wall, pole, book-mount, horizontal orientation with fan according to similar spec tables. |
Because it supports Band 5 (850 MHz) with a 4T4R configuration, this radio is well suited for macro-cell coverage in low/mid frequency bands — good propagation, better building penetration, wide area coverage.
The 4T4R (rather than 2T) supports higher capacity and better MIMO performance / diversity than simpler 2T2R units.
The “160W” class implies a higher output power capability for this band, aiding coverage.
Being part of Nokia’s AirScale family, the HW is likely “5G-ready” or upgradeable (depending on software/hardware revision) — enabling evolution from LTE to 5G NR.
Modular and standardized design (connectors, interfaces) makes it easier to deploy in macro sites with existing infrastructure.
