Two main draft standards were submitted in October 2009 as candidate technologies for IMT-Advanced, namely IEEE 802.16m and 3GPP LTE-Advanced. However, several details on their functionalities are still open and the research community is racing towards the complete definition of the revolutionary next fourth generation mobile, 4G. In this framework the European Celtic project WINNER+ is bridging together...
The introduction of high speed downlink packet access (HSDPA) implies an enormous challenge for all mobile industry agents. All network operators must ensure complete availability of services by diligently planning and tuning their networks. Drive-test and call-tracing tools significantly help to assess the user plane performance but they can be also useful for troubleshooting potential problems in...
This paper presents SPHERE, a Simulation Platform for HEterogeneous wiREIess systems, and describes its motivation, methodology and implementation approach. This advanced system level simulation platform emulates simultaneously the transmission of GPRS, EDGE Multi-slot, HSDPA and WLAN at the packet level, which allows conducting novel investigations on common radio resource management for beyond 3G...
