SAMU project: tests and improvement of UMTS for users in a car

This paper gives an overview of the French collaborative project SAMU, Advanced Services by Mastering UMTS, dedicated to developing enhanced services for users in a car. For that purpose, complementary research domains have been investigated such as radio resource management, IP over UMTS and the use of software agents. While field trials were planned in the project to validate the outputs of the abovementioned research areas over a UMTS experimental network, the general delay encountered by UMTS manufacturers led the project to investigate alternative experimentation. Hence, a UMTS-TDD software radio platform has been built to show IP based telematics applications over UMTS.
