abra base metals

Licensed Microwave Data Network

 The Abra Base Metals Project (Abra or the Project) is a globally significant lead-silver project located in the Gascoyne region of Western Australia (between the towns of Newman and Meekatharra, approximately 110 kilometres from Sandfire’s DeGrussa Project).

Project Summary

To provide a secure and robust high-speed microwave network from the local Telstra network to the Abra mine site.

The network must:

  • Seamlessly interface into the Telstra network

  • Be rated for the environment

  • Be designed for 99.995% reliability

  • Operate in all conditions

  • Have remote monitoring capability, by client or provider

  • Be cost effective and modular for change or growt

Project Overview

Air Communications supplied a licensed microwave data network linking the Telstra network carrier site (Doolgunna) to the Abra mine site.

To link Doolgunna RT to the Abra site, network repeater sites were installed at Facey, Dunns Range and on the Abra mine site. Miscellaneous lease arrangements were granted.

Mast structures and solar power systems were installed at each remote location and a 50M mast structure was installed at the Abra site which house the microwave links plus accommodate other site RF requirements.

A 3600Mhz broadcast data radio system was installed on the Abra mine mast which allow network connections over the site for SCADA and other remote locations including the airport, village, remote pumps and offices.
