Description

The Cel-Fi Quatra is an enterprise 4G repeater system designed to provide in-building coverage to large facilities and small-medium sized multi-storey buildings.

Quatra is a hybrid repeater design which follows a hub-and-spoke design. The system breaks apart the functionality of an inline amplifier by separating downlink and uplink boost functions between the hub, called the Network Unit (NU), and spokes, called Coverage Units (CU). Specification listed on this page are for the Network Unit only.

The system requires one Network Unit and between one and four Coverage Units which are interconnected by ordinary Ethernet cables. A typical system design would use one CU per floor on a multi-storey building, or one CU per warehouse in an industrial facility. Each CU is powered via PoE from the NU.

Ethernet cables are used to transmit a digital signal between NU and CU, allowing lossless connectivity up to 100 metres and up to 200 metres with a compatible range extender. This unique implementation allows Quatra to solve ordinarily complex 4G coverage problems with ease.

The Quatra repeater can relay up to four bands simultaneously, with several bands supporting 2x2 MIMO for high speed data applications.

Quatra must be carefully designed and configured in order to correctly function. As a hybrid DAS unit, mobile network operators require Powertec to conduct extensive RF design, which must be submitted to the operator in order to obtain approval for use.

Q34 (Q1000) has been made End-of-Life by the manufacturer.
