We present our investigation into the potential of the general packet radio service (GPRS) and enhanced GPRS (EGPRS) with respect to video streaming. Taking real video sequences as the basis for a video streaming load generator, the simulation tool GPRSim that comprises a prototypical implementation of the standardized GPRS/EDGE protocols has been extended. Results have been obtained for simulations of actual as well as future scenarios. Both fixed and on-demand packet data channel (PDCH) allocation techniques have been considered to carry the generated traffic which contains video streaming as part of a traffic mix additionally comprising e-mail and World Wide Web (WWW) traffic. The analysis of the traffic performance measurements shows the limited capacities of GPRS networks to carry real-time data. However, the simulation results also indicate that EGPRS, as the enhanced system, is able to be a bearer, on a limited scale, for real-time traffic.
