5G Infrastructure Cabling: Huawei’s High-Frequency Harness Design
Introduction
The deployment of 5G networks is one of the most infrastructure-intensive projects in telecommunications history. One of the lesser-discussed but mission-critical elements is high-frequency cabling¡ªespecially wire harnesses used in base stations, massive MIMO antennas, and fiber/coax hybrid links. Huawei, a global leader in 5G technology, has developed proprietary harness systems capable of operating reliably at frequencies up to 39 GHz. This article explores how Huawei engineered these systems to balance bandwidth, power, and durability.
5G Cabling Requirements
High frequency: >6 GHz (mmWave and FR2 bands)
Minimal signal loss: Insertion loss <1 dB>
