Description
The Cel-Fi QUATRA 4000e Network Unit (NU) forms the central component of Nextivity's flagship hybrid DAS solution. QUATRA 4000e is an enterprise-grade multi-operator digital repeater system used to resolve poor in-building 4G-5G mobile coverage in medium-sized buildings.
QUATRA 4000e uses ordinary Cat5e/Cat6 ethernet cables to interconnect up to six Coverage Units (CU) placed around the building, and an additional six CU when using the Fibre Hub (purchased separately). The Network Unit establishes a strong interconnection to the network operator, either through a donor antenna or Small Cell input, and each Coverage Unit then outputs this signal at full strength (+16 dBm per channel).
As a hybrid-digital solution that uses ordinary ethernet cabling, installation of the system is quick and simple.
The Network Unit supports up to four Mobile Network Operators, allowing coverage from all networks to be improved simultaneously. This includes support of Private LTE/5G networks, allowing the combination of both public and private networks inside the building.
Q4000e NU supports the commonly utilised mid-bands, B1 (2100 MHz), B3 (1800 MHz), B7 (2600 MHz), TDD B40 (2300 MHz) along with B8 and B20 low-bands common in Europe.
The Q4000e NU supplies power to each CU using Power over Ethernet (PoE). The maximum distance of each CU from the NU depends on the cable type. Most Cat5e cables support a distance of up to 100 metres (200 metres with the QRE), Cat6 cables support a distance of up to 150 metres (300 metres with the QRE). The Fibre Range Extender (QFRE) allows CU to be placed up to 2 kilometres away.
The QUATRA Fibre Hub expands the NU capacity by supporting an additional six CU. The Fibre Hub connects via the NU's SFP port and can be placed up to 2 km away.
