How Passive DAS Solves Indoor Coverage Challenges in the 5G Era

Structural Advantages of Passive DAS

Passive DAS consists of passive components such as antennas, feeder cables, power splitters, and directional couplers. Its simple structure requires no additional power supply. In the 5G era, indoor environments are complex and diverse. Passive DAS, with its flexible deployment capabilities, can quickly adapt to different scenarios. It avoids electromagnetic interference caused by active equipment, ensuring the pure transmission of 5G signals and effectively addressing indoor coverage challenges. Additionally, the installation and maintenance costs of passive DAS are low, making it suitable for large-scale indoor 5G signal expansion.

Working Principle of Passive DAS

Passive DAS uses power splitters and couplers to transmit signals from external sources to various antenna nodes through fiber optic or coaxial cables. These nodes then evenly distribute the signals indoors. Unlike active systems, passive DAS does not require additional power support, thereby reducing maintenance costs and improving system stability. Especially in areas requiring large-scale signal coverage such as high-rise buildings and subway stations, passive DAS can effectively solve 5G indoor coverage challenges.

Signal Transmission of Passive DAS

Passive DAS introduces macro base station signals indoors through feeder cables and uses devices like power splitters and directional couplers to reasonably distribute the signals, achieving comprehensive indoor coverage. In enclosed spaces or weak signal areas, passive DAS can capture and forward 5G signals through multi-directional combinations, ensuring stable signal reception in every corner. This efficient signal transmission mechanism makes passive DAS an ideal choice for 5G indoor coverage.
