Keeping a Construction Project on the Fast Track

The Challenge
Theft and vandalism are problems on constructions sites all over the world. People don’t just walk away with building materials; they’ll even siphon the fuel out of construction machinery after it has been parked for the night. Installing security equipment like IP cameras can cut losses dramatically.

But construction sites don’t always have access to wired Internet infrastructure. When a European construction company went to work on a new high speed rail link in western France, the construction site kept moving as the project progressed, and wired Ethernet connections were rarely available along the new right of way. They needed a mobile, wireless solution that could support real time security applications. Because of the locations involved, they required a solution with wide temperature range, remote management capability, secure VPN tunneling, and the able to provide Internet access virtually anywhere.

The Solution
A European M2M wireless communications company went to work on the problem. They equipped the construction vehicle gas caps with RFID motion sensors, which automatically send out an alert if a movement in the sensor or the gas cap exceeds specified parameters. The RFID sensors report to an RFID reader that is connected to a B+B cellular router, which can provide cellular Internet connections for both local area networks and individual devices. With multiple built-in hardware interfaces, the cellular routers are able to aggregate disparate protocols and technologies that include Wi-Fi, Ethernet, RS232/422/485 and even Modbus. Connecting to the RFID readers was not a problem.

The wireless communications company connected the remote video cameras to the B+B cellular router as well. When alerts are received at the central security office they are accompanied by a live video feed, and security personnel can take appropriate action.
