Newmont Mining Powers 24/7 Gold Mining Operation with Exalt Microwave Backhaul Systems

200-Megabit Ethernet Microwave Radio Links Support Fault-Tolerant Dispatch and Control System for Global Gold Producer

CAMPBELL, Calif., January 19, 2010 – Exalt Communications, the company that is reinventing microwave backhaul, today announced that Newmont Mining Corporation (NYSE: NEM), one of the world’s leading gold producers, has deployed Exalt microwave radio systems to support round-the-clock operations at its open pit gold mine near Carlin, Nevada. This deployment follows other purchases of Exalt radio systems for deployment at Newmont Mining operations in Australia, Ghana and Indonesia.

In this deployment, Newmont Mining worked with radio systems consultant KNS Communications of Denver, Colorado, to plan and install Exalt split-mount and indoor microwave radio systems. The Exalt systems provide a 200 megabit-per-second Ethernet backbone that delivers computer-aided dispatch, traffic management and inventory tracking information to 2.4 GHz radio systems on board each of the 150+ trucks, drills, shovels, loaders and other equipment at the mine, which stretches across 24 miles of the Carlin Trend.

“We run our operations 24 hours a day, 365 days a year, and our ability to minimize downtime depends on making sure all of our equipment is being used productively at all times,” said Boyd Burden, senior communications technician at Newmont Mining. “Exalt radio systems give us totally reliable operation, and that helps us keep all of our equipment running at peak efficiency.”

Exalt split-mount radio systems configured to use the 11 GHz frequency bandare used to further reduce the potential for interference in an area adjacent to another mine’s radio network. For the other links, the company opted for Exalt indoor radio systems configured to use the 5.4 GHz frequency band. The radio hops reach from 7 to 10 miles each.

“Exalt microwave radio systems allow operators like Newmont Mining to support mission-critical communications and information transport with complete confidence,” said Amir Zoufonoun, president and CEO of Exalt Communications. “Our exclusive performance and reliability features allow customers to use high-speed wireless connectivity without the reliability and performance issues associated with legacy microwave systems. Plus, our broad product portfolio provides customers with the ultimate in flexibility to design and deploy a network that meets their specific performance and TCO requirements.”

All Exalt radio systems are carrier-class systems offering guaranteed link availability, guaranteed throughput and low, constant latency. Systems are available in frequencies from 2 to 40 GHz and in capacities from 10 Mbps to more than 700 Mbps per channel, providing a range of options to fit countless network applications. Designed to enable a smooth transition to IP, they offer native support for both TDM and Ethernet, and are fully software configurable and upgradeable. For easy and secure management using third-party network management systems, Exalt systems support SNMP v1, v2c and v3. Data security is provided by available FIPS 197-compliant AES 128-bit and 256-bit encryption that adds zero latency to the transmission. To simplify installation and maintenance, all Exalt systems feature an embedded manual and most include a built-in spectrum analyzer.
