Uninterrupted data transmission over GSM and application to health services

This paper seeks to evaluate the sufficiency of the GSM radio functionality in supporting the case of patient's data transmission from a moving ambulance. Employing the TCP/IP and the UDP/IP protocol duos, repeated transmissions of a file are carried out. The reliability of the data coding used by the GSM is examined whilst the stability of the connections realized in the GSM air environment is investigated. Finally, suggestions are made and solutions are proposed in order that disconnections, due to radio link blackouts, to be avoided.
