While using electric power lines in a building as the cabling for an office LAN is not a common occurrence, a power-line networking project undertaken by the Transportation Security Administration (TSA) could represent an emerging trend. The TSA is implementing a pilot project that will use power-line technology at several airports, beginning in late January 2007. The agency will utilize products provided from Telkonet to speed up the network communications, some of which are still dialup connections, between field operatives at airports and the TSA's Washington, D.C. headquarters. Ultimately, the TSA will wire airport passengers and other screening systems, cameras at ticket counters, and passport readers for Internet access via the power-line technology. The project will initially be used at only a few airports, but it could spread to as many as 380 airports as the TSA begins its $100 million project to wire all airports internally for broadband access. There are two different kinds of power line systems available. One provides Internet access through external power lines, and the other acts like a LAN by using the internal electrical wiring of a building for network transmission. The second type is what the TSA will use. Broadband over power lines is a carrier-operated technology, while in-building systems are set up by end users. While there are advantages to using the power-line method, speed and security represent continuing concerns. Additionally, wireless technology represents a viable alternative.
