473966A(AHCA) A Nokia AirScale Remote Radio Unit

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:

• 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.
