NEW ORLEANS--If you passed it on the freeway, you might think this was an ordinary Verizon Wireless truck on its way to maintain equipment. Look a little closer, however, and you'll see this is a different kind of vehicle. Known as a COLT (cell on light truck), it's actually a fully contained cell site that can be driven to almost anywhere in the country in a matter of hours. Verizon can deploy one of its 100 COLTs to a disaster-stricken area to boost the carrier's network for residents and emergency workers. On either side of the cab are antennas that can reach 60 feet tall.
