WhereNet Corp., a vendor of wireless systems for tracking and managing transportation equipment, has released version 4.0 of the WhereNet Marine Terminal Solution (MTS).

The single, integrated wireless system includes WhereNet's Visibility Software Server (VSS) middleware; container tracking application-specific software (MTS); a hardware infrastructure consisting of WhereLAN locating access points, and the new WhereTrack controller. The last integrates a WhereTag active RFID transmitter, GPS receiver, and Wi-Fi modem into a single ruggedized device for container-handling equipment tracking.
