"Tait developed a complete turnkey solution for Cerrejón, providing the infrastructure, installation and integration of the RF equipment and power sites. This, and the reliability of the RF equipment, gave Tait a huge competitive advantage."

Mario Javier Granados

Situation


Cerrejón needed robust, reliable communications for about 1,500 staff spread over its range of operations operations spanning 93 miles. The company was communicating through conventional radio networks before implementing a Tait solution, and was experiencing high congestion levels on the networks.

Efficient communications between Cerrejón Coal’s widespread operations is critical to productivity. The 90 teams working at different levels of the operation were sharing conventional radio channels, and users often had to wait for a conversation to finish before the channel was free to make a call. Also, users could hear other’s conversations, which meant security was compromised.

Response


The company chose a seven-site, 48-channel TaitNet TN3100 MPT 1327 trunked system for communications at the mining operation. The greater channel availability of the trunked radio network means users at Cerrejón Coal can communicate when they need to, without having to wait for a channel to become free.

The system provides for some 1,500 users, from the truck drivers transporting coal from the mine to the trains, to the port terminal staff and maintenance staff. Two TaitNet 1541 Node Controllers have been implemented at Cerrejón, a main node and a standby node, and three Line-connected Dispatcher Terminals are used so dispatch staff can efficiently manage all radio system users.

The trunked system is also interfaced with Cerrejón’s PABX network and PSTN lines, providing integrated communications across all sites.

Outcomes


Cerrejón staff now have robust and reliable communications at all times. Group calling has provided greater efficiency, and private, secure conversations are now possible.
