475081A ( AHPCDB) A Triple-band Remote Radio Head (RRH) Designed For Macro Cellular Sites

The 475081A (AHPCDB) is a high‐performance, triple-band macro remote radio head from Nokia’s AirScale portfolio. It’s designed to support coverage and capacity across three key cellular bands (B5/B8/B28) in a 2T4R configuration with ~240 W output, thereby enabling operators to deploy multi-band LTE (and potentially 5G) sites with fewer modules, less footprint, and operational simplicity. It’s especially suited for macro base station sites where multi-band coverage is needed, and where uplink/receive performance and future evolution are important considerations.

• The 475081A (also referenced by the internal code AHPCDB) is a triple-band remote radio head (RRH) designed for macro cellular sites. 

• Its full designation in the product list is “AirScale Tri RRH 2T4R B5/B8/B28 (n5/n8/n28) 240 W" — meaning it supports three frequency blocks (Bands 5, 8, 28 including their 5G “n" equivalents) in a 2Tx / 4Rx configuration with ~240 W output power. 

• It belongs to Nokia’s “AirScale Radio" family targeted at modern LTE and 5G deployments, including macro-coverage scenarios. 

Here are the major features and what they mean:

• Triple-band support (B5 / B8 / B28, and corresponding n5/n8/n28)
  This allows a single RRH unit to handle three different frequency bands. That leads to reduced site hardware (fewer separate radios), simplified installation, and easier multi-band coverage.

• 2T4R configuration
  “2T4R" means two transmit antennas (or chains) and four receive chains. This configuration boosts receive diversity/quality (via 4R) while keeping a moderate transmit side (2T). It’s well suited for macro sites where coverage and uplink sensitivity matter.

• ~240 W total RF output (in the triple-band scenario)
  While exact per-band output may vary, the product listing indicates a 240 W class device. 

• AirScale platform compatibility
  As part of the AirScale portfolio, this RRH supports features such as LTE + 5G readiness (depending on software/hardware version), multiple carriers, high‐order modulation (e.g., 256QAM), and modern interface support. 

• Optimized for macro deployment
  The product is designed for outdoor macro-cell base stations (on towers, rooftops) where multi‐band coverage, high power, and efficient site footprint are required. For example, Nokia’s macro RRH page mentions “extended coverage with high performance" and “compact form factor enables flexible deployment". 

• Upgrading a legacy macro cell site (e.g., replacing older single-band radios) to handle three bands simultaneously, thereby reducing the number of installed radios and cabling.

• Locations where coverage in multiple bands (low band, mid band) is required for both capacity and coverage (for example B28 for good propagation, B5/B8 for urban/mid‐density).

• Operators looking to roll out LTE and/or 5G on existing sites with an RRH that can support multiple bands from day one (or with minimal upgrades).

• Site conditions where it’s advantageous to have 4Rx for better uplink sensitivity or receive diversity (important for coverage, edge users, uplink heavy applications).
