In-Building Coverage

The Need for IBS

We rely on being connected through our cell phones. Yet 80% of all mobile traffic are generated indoors, notwithstanding Wi-Fi. Today, having cellular signal indoors is more important than ever.
Today, millions of buildings around the world need to bring cellular signals inside. Midsized buildings, in particular, have been massively underserved. All this is growing the IBS market—fast.

IBS Coverage

IBS has long since saturated highly visible public venues like airports and stadia. There is also an endless selection of IBS products for the home. However, a highly functional, easily installable and affordable solution for the middle market has never appeared—until now, with Zyxel.



Zyxel’s DAS solutions combine simple yet highly capable units through special use of CAT5 technology. Simplifying previous designs, each system uses one ZoneDAS or SlimDAS Base Unit (BU) to control and power multiple Remote Units (RU) for coverage. Optional Extenders double RU deployment range and multiply supported RUs. Each system supports multiple independent 20 MHz-wide channels / bands / operators, multiple coverage zones (each up to 2,500m2), and a complete set of real-time software control.
ZoneDAS Base Unit
  • Supports up to 4 channels / bands / operators
  • Connects up to 8 Remote Units and / or Extenders
  • Great for hotels / hospitals / high-rises / shopping malls
SlimDAS Base Unit
  • Supports up to 2 channels / bands / operators
  • Connects up to 4 Remote Units and / or Extenders
  • Great for motels / wineries / mid-rises / factories
  • Adds connectivity (including power) for up to 8 more RUs
  • Multiple Extenders enable up to 32 RUs for SlimDAS and 64 RUs for ZoneDAS
  • Doubles RU deployment distance (to 200 meters)
  • Directly controlled by the host BU
Remote Unit
  • Provides up to 2500m2 of cellular coverage
  • Software switchable dual-mode antennas (external-antenna versions also available)
  • Powered by host BU/Extender through PoE
  • Easy CAT deployment, up to 100m from host Extender/BU

CAT5 DAS Scenarios

ZoneDAS + LineExtender

10,000 ~ 20,000 m2 floor space

For SMB/residential buildings that require 5 to 8 signal coverage areas, optionally with off-air signal sources.


20,000 ~ 160,000 m2 floor space

For commercial/industrial buildings that require more than 8 signal coverage areas.


5,000 ~ 10,000 m2 floor space

For SMB/residential buildings that require 2 to 4 signal coverage areas, optionally with off-air signal sources.


10,000 ~ 80,000 m2 floor space

For residential/commercial buildings that require more than 4 signal coverage areas.

MagicOffice Repeater

MagicOffice repeater is a quad-band repeater and supports coverage space up to 900 square meter. It is the best solution to extend mobile signal into small offices, café, bars, restaurants or shops. MagicOffice repeater has intuitive LED signal indicator that enables worry-free rapid installation with soft coaxial cables for system integrators, meanwhile guarantees outstanding voice and data quality for business venue owners.


Zyxel’s SymmRepeater is a revolutionary RF repeater that offers previously unattainable features and advantages through its innovative dual-device design. Notable among these is its amazing 400m zero-loss amplification range, world-leading 100 dB gain, automatic isolation detection, and patented echo-avoidance technology. And it does these at full 4G or 5G FDD speeds, with excellent signal quality, web interface, and remote management/monitoring.
Indoor Housing
  • Comes in Donor or Service configurations
  • Svelte, inconspicuous design
  • Great for ceiling or wall installation
  • Available bi-pole antennas
IP65 Housing
  • Comes in Donor or Service configurations
  • IP65 water/dust resistant sealed design
  • Great for pole or wall installation
  • Available bi-pole or patch antennas

SymmRepeater Scenarios


2,500 m2 floor space

SymmRepeaterPRO is built for mini Passive DAS design for professional IBS system integrators. It is a perfect solution for high-rise building floor, elevator or tunnel scenarios that are very far from the signal source. Or camping grounds, towns/villages at mountains wish to improve signal coverage.


> 3,600 m2 floor space

Built-in panel antenna for donor unit and signal extension through MultiSite Repeater, SymmRepeaterENTERPRISE is installer-friendly for IT-based system integrators. It is an ideal solution for elevators, tunnels, or residential buildings that require off-air signal coverage reaching into higher floors, lower basements, or inner areas.

SymmRepeaterENTERPRISE + MultiSite

3,600 m2 x 7 floor space

For multi-floor scenarios, SymmRepeaterENTERPRISE repeater features with 2 bands support and built-in 2 expansion ports on the service unit capable of cascading up to 6 MultiSites, ideal for multi-floor deployment where outdoor signal is 1 bar only, e.g. country side residential buildings, rural multi-floors offices/basements, hospitalities and warehouses.

CAT5 DAS + SymmRepeaterPRO

5,000 ~ 20,000 m2 floor space

Repeaters are often good enough alone. But for SMB/residential buildings that are large scale at suburban areas, or too far for an operator to care, by using Zyxel SymmRepeater and CAT5 DAS altogether the family enables multi-zone off-air signal coverage.
