Zyxel’s Active Distributed Antenna System (Active DAS) solution uses Ethernet or optical fiber cabling, with a system architecture similar to WiFi. With simplified system planning and deployment, installation is fast and efficient, significantly reducing labor and construction costs.
What is Active DAS?
Active DAS (Distributed Antenna System) leverages active components—such as a Base Unit(BU) at the head-end—to capture RF signals and distribute them to Remote Units(RU) with built-in antennas throughout the building via Ethernet cables or fiber optics. If more coverage is needed, an optional Expander can be added to increase the number of Remote Units.
Since all components in an Active DAS are active devices equipped with signal amplification or conversion capabilities, the system can effectively compensate for signal loss during transmission. This results in negligible signal attenuation across the network. Furthermore, the output power of each Remote Unit can be precisely configured up to its maximum limit, making system planning more straightforward, intuitive, and efficient.
Why active DAS?
In today’s building environments, where data-intensive and real-time communication needs are rapidly increasing, legacy passive DAS can no longer meet user expectations. Active DAS (Active Distributed Antenna System) offers a flexible, scalable, and high-performance indoor wireless communication solution, ideal for middle to large office buildings, healthcare facilities, campuses, hotels, and commercial centers.

WiFi-Like System Planning
Ultra-Simple System Architecture!
With Zyxel Active DAS Solutions, designing a DAS system is as simple as planning a WiFi network. The Base Unit (BU) functions like a WiFi Controller, the Expander acts as an Ethernet Switch, and the Remote Unit (RU) operates like a WiFi Access Point (AP).
Unlike traditional passive DAS, which requires complex and time-consuming signal attenuation calculations, Zyxel Active DAS Solutions eliminate this hassle—just install RUs where coverage is needed, just like placing WiFi APs.
Each RU features a built-in active omni-directional antenna, ensuring seamless indoor coverage:
n78 band: Covers up to 30m × 30m (900m²).
Other RF bands: Covers up to 50m × 50m (2,500m²).
The intuitive, scalable design makes deployment quick and future expansions effortless.
Flexible Modular System for Up to 4 or 8 Bands
Zyxel Active DAS solutions support 1 to 4 RF band modules, or up to 8 modules (ZoneDAS Two Plus only). Our system allows you to configure a combination of frequency bands based on your needs, creating a customized DAS solution with up to 4 or 8 bands. With a selection of RF modules covering different bands, the modular design provides exceptional flexibility, ensuring you only invest in the components you need. If future modifications or upgrades to the band configuration are required, simply swap out the RF band modules for a seamless upgrade—no unnecessary costs or complex adjustments. (Note: Supported bands and bandwidth may vary by model.)
4G+5G All-in-One
No matter if it’s FDD Band 1, Band 3, Band 8, Band 28 for 4G or 5G, or even TDD bands like n78 and n41 specifically for 5G, you can select and combine these RF band modules for a single system to create a 4G or 5G DAS, or a system for both. Supporting 256QAM with low signal latency, our solutions seamlessly relay signals of different generations of mobile communication technologies. Whether it is GSM, UMTS, WCDMA, LTE, HSPA, NR, or NB-IoT, all signals transmitted within the supported frequency range can be supported simultaneously.
Multi-Carrier Support
Each BU’s RF band module (RF POI module) features either 1 or 4 SMA signal input ports, allowing the system to accept 1 or 4 sub-channel signal sources. Within the supported bandwidth, the system can integrate signals from 1 or multiple mobile operators. It automatically equalizes the signal strength of up to four inputs from different operators before combining and distributing them, ensuring seamless signal relay.
Flexible Signal Source
No longer solely dependent on MNO-provided base station signals, Zyxel Active DAS Solutions offer flexible sourcing options for DAS deployment.
In addition to direct connections with telecom base stations (Macro, Micro, Small Cell, ORAN-RU), the system can also receive over-the-air signals via outdoor antennas. These signals can be amplified using low-power cellular repeaters (brand-agnostic) before being fed into the system. This flexibility empowers even general IT-based system integrators to independently deploy DAS projects with ease.
Highly Scalable
Each system supports up to 8 optional Expander Units, accommodating a maximum of 64 or 128 Remote Units (RU). Each RU features a built-in antenna for every RF band module, ensuring a hassle-free installation—simply place an RU where coverage is needed, and the setup is complete.
Even in ultra-large buildings covering up to 160,000m², a single system can provide seamless and reliable coverage.
Need to expand coverage in the future? No problem! Just add more RUs as needed—without affecting the coverage of the existing system.
Ethernet or Optical Fiber Cabling
Say Goodbye to Coaxial Cables! Our active DAS solutions utilize Ethernet or optical fiber cabling, enabling faster deployment, simpler installation, and significantly reduced material, equipment (e.g., cranes), and labor costs.
All-Ethernet Architecture (ZoneDAS & ZoneDAS One)
With optional Expander & Line Extenders, the maximum cabling distance from BU to RU can reach up to 400 meters.All-Fiber Architecture (ZoneDAS Two & ZoneDAS Two Plus)
With optional Expander Units, the system provides higher total relay bandwidth and supports distances up to 5 kilometers from BU to RU.
Connecting to External Antennas
Deploying an RU in every small room may seem excessive—but no worries!
Zyxel ZoneDAS Series offers a hybrid DAS option with RU4C (RU with 4 connectors). Unlike standard RUs, RU4C does not have a built-in antenna. Instead, it combines all RF bands and outputs the signal through 4 SMA ports.
These SMA ports can be connected via coaxial cables, splitters, and couplers to multiple external indoor antennas (omnidirectional, directional, panel antennas, etc.), offering a cost-effective solution to extend coverage into multiple compact spaces.
This setup effectively mitigates signal loss caused by walls and doors, ensuring seamless connectivity even in dense, partitioned environments.
Intuitive Management & Remote Monitoring
Simply connect the BU to a computer, and you can effortlessly manage all system components—including all Remote Units, Expanders, Line Extenders, and RF band modules—through an intuitive Web GUI (Graphical User Interface).
With VPN access, remote system management, monitoring, and configuration are easily achievable. Additionally, the system supports SNMP and syslog messaging, ensuring seamless integration with third-party network management software.
