* Aether Systems of Owings Mills, Md., said U.S. Xpress Enterprises, the fifth-largest publicly owned truckload carrier in the country, signed a multiyear contract to buy wireless and asset-tracking services. U.S. Xpress will replace its existing satellite-based tracking system on 5,500 of its trucks with Aether's MobileMax product.

Installation will be completed on most U.S. Xpress trucks next year. Aether spokesman Greg S. Abel declined to comment on financial details of the contract but said this deal makes U.S. Xpress one of Aether's largest clients.
