Zyxel Dual Band Symm Repeater

High-performance dual-symmetric cellular repeater for stable 2G/3G/4G/5G coverage in buildings. Ideal for offices, hotels, industrial sites, retail spaces, underground garages and basement areas.

Highlights

Dual-band support – targeted amplification of two frequency bands (e.g. B1/B20, B3/B8, etc.), depending on variant and network.

Dual-symmetric architecture – active amplification on both donor and service paths for high stability and range.

Automatic gain control – auto-gain and protection functions reduce overdrive and feedback.

Large indoor coverage – depending on configuration, up to more than 2,500 m² possible.

Rugged design – donor unit weather-resistant (IP65), service unit for indoor use.

Fast installation – easy planning, flexible antenna topologies.

Technical Data Applications

Short Description

The Zyxel Dual Band Symm Repeater improves in-building mobile coverage by capturing, processing and redistributing the outdoor (donor) signal efficiently indoors (service). With its symmetric signal routing and finely adjustable gain, the system provides reliable voice quality and stable data rates even in challenging environments.

What does “dual-symmetric” mean?

Both the path from the roof (donor) to the building and the indoor distribution (service) are actively amplified. This minimizes cable losses and ensures consistent levels across long distances.

Specifications may vary by model or region. For a specific project, please specify the desired band combination and performance variant.

Applications

Underground garages, basements, production halls
Retail areas, office buildings, hotels & hospitals
Educational and administrative buildings
Buildings with heavily attenuated outdoor signals

Planning & Installation Notes

Band selection: choose bands according to local network coverage and provider.
Antenna planning: donor antenna with clear line of sight; distribute indoor antennas evenly.
Cable routing: minimize losses using high-quality 50 Ω coaxial cables and short runs.
Avoid feedback: ensure sufficient antenna spacing & correct level adjustment (use auto-gain).
Documentation: record measurements and levels after commissioning.
