DATAMOVIL: a practical implementation of TRADAMO mobile data transmission protocol

The DATAMOVIL system has been developed for use by security forces, computer-aided dispatchers, and wherever an application requires highly reliable voice and data communications for a mobile fleet. A protocol called TRADAMO has been implemented as a key part of this system. This mobile data transmission protocol is presented along with the ASIC (application-specific integrated circuit) that implements part of it. The system allows a large reduction in the mean air time required for a mobile user by channeling part of the voice traffic as status message traffic, and also allows transparent data transmission between mobiles and host computers, even in the field.<
