📡 Ericsson AIR 6449 B42 — 5G NR Radio, Mid-Band (64T/64R)

Product Overview

The Ericsson AIR 6449 B42 (part number KRD 901 119/11) is a high-capacity, mid-band 5G New Radio (NR) unit offering 64T/64R configuration. It is designed to support high-throughput, dense traffic environments and is part of Ericsson’s Antenna Integrated Radio (AIR) family. 

Key Features

• Mid-band Support: Operates in n42 / B42 frequency range, ideal for 5G deployment in regions using 3.4–3.6 GHz or corresponding bands. 

• Massive MIMO 64T/64R: Delivers large spatial multiplexing and high spectral efficiency, enabling high capacity and superior user experience. 

• 320 W Output Power: Typical radio power reaching 320 W for dual-mode (n42 / B42) operation. 

• Antenna Integrated Design (AIR): Combines radio and antenna into a compact integrated unit, reducing cabling, losses, and site complexity. 

• Beamforming & MU-MIMO: Support for beamforming and multi-user MIMO to improve coverage, capacity, and quality under high-load conditions. 

• Mixed Mode (NR + LTE): Can be deployed in pure NR mode or in mixed mode with LTE fallback or coexistence. 

• Outdoor Robustness: Built for outdoor deployment with weatherproof design. 

• Size & Weight: Dimensions around 99 cm × 74 cm × 35 cm; gross weight ~ 42 kg.

Typical Technical Specifications

Applications & Use Cases

• Dense Urban & Suburban 5G Deployment: The 64×64 MIMO makes it ideal for high-demand areas needing high throughput and capacity.

• Mid-Band 5G Coverage: B42/n42 support ensures a balance between coverage and capacity.

• Small Cell / Macro Hybrid Sites: As an AIR unit, it's suitable where integrated radio + antenna helps reduce site complexity and cabling losses.

• Network Densification: Useful for filling coverage gaps and boosting capacity in existing 5G networks.
