The challenge
The ANZ Centre, formerly known as the Robert Jones Tower and the Coopers & Lybrand Tower, has been one of Auckland’s premier office spaces since its completion in 1991. At the time of construction, mobile technology was in its infancy – 4G and 5G were still decades away. Fast forward to today, and mobile connectivity is an essential part of doing business.
The 42 floor building, 32 tenanted floors and a public carpark, faced significant connectivity challenges:
- Inconsistent 4G and 5G coverage throughout office levels, making calls and data unreliable.
- No coverage in the carpark, posing potential health & safety risks for tenants and visitors.
- Fragmented solutions – while some tenants had installed their own small-scale systems, coverage across other floors was patchy at best.
The solution
ANZ Centre’s property manager, CBRE, knew that tenants needed seamless, building-wide coverage to stay connected, safe, and productive.
With extensive experience working alongside New Zealand’s major mobile network operators, Kordia was enlisted by CBRE to design and deliver a bespoke Distributed Antenna System (DAS) that could bring reliable 4G and 5G connectivity to every corner of the building.
The solution included:
- A hybrid DAS, using a combination of fibre and coaxial cabling, enabling seamless coverage across all 32 tenanted floors and the carpark levels.
- Passive antennas, strategically placed to ensure consistent mobile coverage across office spaces and into traditionally challenging areas like the lfits and underground carparks.
- A collaborative design and approval process with all major telcos, ensuring the system delivered full multi-carrier coverage.
- A complex nine-month retrofit installation carried out within a live, fully tenanted building – carefully planned to minimise disruption.
