Product Overview

The Ericsson AIR 3227 B42 KRD901188/11 is an Antenna Integrated Radio designed for high-capacity TDD LTE and 5G NR deployments in the 3400–3600MHz Band 42 spectrum.

It combines radio and active antenna functions in a single outdoor unit and uses a 32T32R Massive MIMO architecture with adaptive beamforming to improve network capacity, coverage and spectral efficiency. Public technical references list the AIR 3227 B42 with 200W maximum RF output, 128 antenna elements, and 2 × 25Gbps eCPRI interfaces.

The unit is designed for macro-site deployment and is especially suitable for mid-band 5G network expansion, capacity upgrades and modernization projects.

Linkworld Telecom supplies Ericsson AIR 3227 B42 units in new, used or refurbished condition, depending on current stock availability.

Technical Specifications

The dimensions, weight, 32T32R configuration, 200W output and 25G eCPRI interfaces are listed in public AIR 3227 B42 technical references.

Massive MIMO & Beamforming

The Ericsson AIR 3227 B42 uses 32T32R Massive MIMO to improve both coverage and network capacity.

Its integrated active antenna architecture supports:

• Digital beamforming

• MU-MIMO

• Dynamic beam steering

• Improved spectral efficiency

• Better user throughput

• Higher capacity in dense urban networks

This makes the AIR 3227 B42 particularly suitable for mid-band 5G deployments where operators need both coverage and high traffic capacity.

LTE & 5G NR Support

Public technical references describe the AIR 3227 B42 as supporting:

• LTE TDD

• 5G NR

• LTE / NR mixed deployments

One public equipment reference lists support for up to 4 LTE carriers, up to 2 NR carriers, and mixed-mode combinations depending on network configuration and software.

Actual carrier capacity depends on:

• Software release

• Baseband configuration

• Network architecture

• Licensing

• Deployment mode

25G eCPRI Connectivity

AIR 3227 B42 is designed for newer Ericsson baseband architectures and uses high-speed eCPRI instead of older CPRI-only connectivity.

Public specifications list:

• 2 × 25Gbps eCPRI interfaces

This makes the radio suitable for high-capacity Massive MIMO and 5G base station deployments.
