VoIP plays role in $800 million construction project

Tools

A unified WiFi-VoIP communications system was employed in the construction of a massive dam in remote Mexico. The $800 million hydroelectric El Cajon dam project took four years to complete and relied on an $8 million Cisco-based telecom system. The network was used to transmit 3D architectural models, news and even payroll information. The system was also credited in part for the unprecedented safety record of the project. As many as 10,000 people worked on the site with no fatalities.

When the dam was completed earlier this year, the IT and communications infrastructure was packed up and stored in a warehouse. El Cajon could represent a new business model for temporary infrastructure deployments, and for an open access spectrum license.
