Outdoor Antennas on the Flat Roof
Directional donor antennas, mast-mounted and aligned to the target cells. Includes lightning and surge protection; weatherproof design for long-term performance.
Office Building Reference Installation – Zyxel ZoneDAS & Nextivity Quatra
Roof Cabinet: Quatra NUs & Remote Management
Ventilated, weather-protected cabinet with 2× Quatra NU (Telekom & Vodafone) and an LTE router for remote administration. Quatra (pre-amplifier) and ZoneDAS can be remotely managed separately. Protection concept: lightning/surge protection at the entry point.
Quatra CUs → Combiners → ZoneDAS Base
2× Quatra CU receive the signals and pass them via external antenna outputs to combiners that separate B1 (2100 MHz) and B3 (1800 MHz) per operator. The four signals are then fed into the ZoneDAS Base.
Distribution via Cat7 & Line Extenders
The ZoneDAS Base distributes Telekom B1/B3 and Vodafone B1/B3 via Cat7 to Buildings 1–3, partly using line extenders. The total Cat7 run from the Quatra NU to the Zyxel RU can be up to 600 m.
Extender Units in the Buildings
In each of the three buildings, two extender units are installed on different floors in tenant server rooms – acting as local distribution nodes, in some cases with additional line extenders.
Remote Units Throughout the Building
Per floor, typically two RUs are mounted centrally in the corridors under suspended ceilings. In total, 46 remote units provide near-blanket coverage for Telekom & Vodafone (B1/B3).
