5G DAS 有线频移与单缆 MIMO5G DAS Frequency Shifting and Single-cable MIMO

该技术用于既有室分系统升级:通过频移复用原有同轴线缆,减少重新布线,让传统 DAS 更快进入 5G MIMO 覆盖。This technology upgrades existing DAS through frequency shifting over legacy coaxial cable, reducing rewiring work and accelerating 5G MIMO coverage.

方案逻辑Solution Logic

5G DAS wired frequency shifting 会将 5G 高频信号转换成较低中频,通过既有同轴线缆传输后,在远端恢复为 5G 信号。它支持单缆 MIMO、DPD、AGC、低噪声和高线性设计,可减少楼宇改造中的施工复杂度。The frequency-shifting solution converts high-frequency 5G signals into a lower IF signal, transmits them over existing coaxial cable, and restores the 5G signal at the remote side. It supports single-cable MIMO, DPD, AGC, low noise, and high linearity.
