Low-power repeaters excel in small projects but struggle with medium and large buildings due to signal loss and distribution inefficiencies. High-power repeaters or telecom signal sources are often impractical due to cost, regulations, and complexity. Alternatives like combining systems or repeated amplification risk noise, oscillation, and compliance issues. Zyxel’s ZoneDAS Active DAS system offers a game-changing solution, leveraging low-power repeaters to deliver efficient, scalable, and cost-effective coverage for larger projects, ensuring flexibility, future upgrades, and support for 5G applications.
Helpless for Medium and Large Buildings?
Your company sells low-power boosters or repeaters, even those operator-specific ones. You even use these repeaters to provide indoor mobile signal coverage system integration projects to your customers. However, due to its low output power, generally speaking, you only provide services to households, small retail stores, and small and medium-sized businesses. For larger buildings, you are helpless? When encountering such needs, can you only let these potential business opportunities pass by? Not necessarily! Below we will explore the challenges of signal coverage system engineering in medium and large buildings, possible solutions, and how to power up your low-power repeater as Popeye eating spinach, Super Mario eating mushrooms, or even Clark Kent who can transform into Superman showing his invincible "superpowers".
Low-power Is Ideal for Small Projects
As the name given, low-power repeaters or boosters amplify and output low-power signals, and their architecture relies on coaxial cables to distribute the signals via splitters, couplers, and ultimately arrive at multiple indoor antennas. However, these passive components naturally cannot avoid the physical attenuation of signal power throughout this whole structure. When the available signal strength that can be used for distribution after amplification is not high enough, naturally you cannot connect too long a coaxial cable, nor too many splitters or couplers to a large number of indoor antennas. In this way, each indoor antenna only gets subtle signal energy (EiRP), and the antenna cannot cover the space where it should be responsible for. Therefore, low-power signal repeaters of course cannot be directly applied to medium and large indoor signal coverage projects. So how should we deal with large-scale cases?
Active DAS: Unlocking the Full Potential of Low-Power Repeaters
You’ve tried every method to acquire more usable signal strength for distribution, but none seem effective. Perhaps it’s time to think if there is a system architecture that eliminates the signal loss caused by coaxial cables and splitters while enabling large-scale signal distribution with low-power signal sources. Yes, that’s exactly the features of an Active DAS.
The concept is simple: feed the signal source into the active system’s master unit, replace coaxial cables with Ethernet or fiber optic cables, substitute splitters and couplers with hub-like devices, and use Remote Units as indoor antennas. Since these are active devices, the power output ......
