Large-format retail warehouse
CEL-FI QUATRA 4000e active DAS
Three-carrier in-building coverage for a high-bay warehouse store, from rooftop donor antennas to coverage units on the roof structure.
A large steel-framed building with high open ceilings and long cable runs, requiring coverage for all three carriers across the trading floor.
Scope delivered
- Three rooftop parabolic grid donor antennas, one for each carrier: Telstra, Optus and Vodafone
- Weather-sealed roof penetrations for the donor cabling
- CEL-FI QUATRA 4000e Network Unit with carrier combining, wall-mounted in the communications area
- Coverage Units mounted on high-level cable tray, feeding SISO panel antennas suspended from the roof structure
- RF exposure (EME) field-strength checks at the donor antennas
- Post-installation monitoring of signal quality for each carrier
- Post-installation signal survey: all nine test areas for each carrier better than Proeye's −95 dBm coverage target (the survey report's own acceptance criterion was −105 dBm)
How the project unfolded
-
Design
Coverage designed around a CEL-FI QUATRA 4000e upgrade, with a predicted coverage drawing for the sales floor.
-
Survey
Donor signal measured on the roof and inside the store before the upgrade.
-
Installation
Old repeater and antennas removed; QUATRA Network Unit, Coverage Units, panel antennas and new donor antennas installed.
-
Testing
Signal survey of nine test areas for Optus, Telstra and Vodafone. Every area passed the report's −105 dBm criterion and Proeye's −95 dBm target.
-
As-built report
Handover report with the installation summary, equipment records and photographs of every coverage antenna.
-
Monitoring
24-hour signal quality monitoring reviewed for each carrier.
Stages and dates come from the project's photographs and documents. Only work shown in the record is described.
