Performance analysis of the S-MIM messaging protocol over satellite

In this paper we present experimental results of the ETSI S-MIM (S-band Mobile Interactive Multimedia) protocol, tested for the first time over a real GEO satellite (EUTELSAT 10A) and through a fully compliant ground platform. In particular, the employed radio interface implements the Part 3 of the standard, i.e. the asynchronous access protocol, especially conceived for the interactive messaging services. The performance assessment done by satellite validates the theoretical results and opens the way for the exploitation of low-power mobile and fixed terminals, thus allowing the proliferation of satellite mass market applications.
