Project: Weipa Alumina Mine
Industry: Mining
Location: Cape York Peninsula, Queensland

The Client

Rio Tinto is an Anglo-Australian multinational and one of the world’s largest metals and mining corporations. Although primarily focused on extraction of minerals, Rio Tinto also has significant operations in refining, particularly for refining bauxite and iron ore.

The Challenge

Rio Tinto’s Alumina Mine at Weipa, in far north Queensland was operating an ageing analogue VHF radio system. CSE Crosscom was engaged to upgrade the existing analogue radio network and associated infrastructure to a Motorola Digital DIMETRA (TETRA) radio system. This required additional towers (to expand coverage), providing and installing communications huts, upgrading underground tunnel communications and microwave links. In addition, CSE Crosscom were required to design the new network to be LTE ready for future wireless data requirements.

The Solution

CSE Crosscom were contracted to provide detailed design, supply, installation and commissioning of the following communications facilities:

• DIMETRA Digital Radio Network
• Communications Huts
• Multiple Towers (50 metres)
• Facility Radio Systems
• Structured Cabling System
• Voice Recording Systems
• Tunnel Communications
• Microwave Design
