Wireless Watch: Ceragon builds highways in the sky, and likely profits

Ever wonder how data flies through the air from smartphone to smartphone or laptop to laptop at ever-increasing speeds? That's enabled by wireless technology, from companies like Tel Aviv–based Ceragon Networks (CRNT). Ceragon, which struggled through 2008 and had a difficult start to 2009, now seems to have great opportunities ahead, due in part to a deal in India and rapidly developing third-generation networks around the world.

Ceragon's job building highways in the sky can be difficult to visualize. To put it simply, the company's equipment connects wireless base stations to a mobile operator's main network, where traffic flows. This transmission technology is critically important to carriers as demand rises for data services and smartphones.
