Voice services has been for a very long time the primary source of income for mobile network operators. Even with the increasing importance of the data traffic, voice services will keep playing a key role and will not disappear with the transition to a networking model based on the IP protocol. Moreover, the key industry players diagnosed years ago that mobile subscribers wouldn't accept a significant...
This paper describes PerformNetworks, which is an enhanced test and research facility for cutting edge mobile communications managed by the MORSE group in the University of Malaga. This facility is an evolution, containing key improvements introduced on top of the work presented in NOMS 2012 [1]. The test environment has been extended to support new features available in LTE-Advanced networks, power...
Smartphones have not only become pervasive, but they will continue evolving in the future. Mobile communications will thus continue to be an area of tremendous research activity, where well-trained professionals will have to address the challenges of such a demanding market. With a background of more than ten years in mobile communications, and based on the insights gained from the Fed4FIRE PerformLTE...
The characterization of traffic performance in cellular networks from the user viewpoint is a costly process involving a large range of protocols and parameters with complex dependencies. Dealing with this challenge requires cross-layer measurements and correlated analysis. The characterization methodology proposed here supports the collection of key information for troubleshooting IP communications...
Railway transportation uses specific technologies such as GSM-R for traffic signaling purposes, but commercial networks could also provide added value services to passengers and transport companies such as CCTV or telemetry. Furthermore mobile users increasingly want to be always connected even when they are traveling. Although current deployed technologies such as 3G provide wide coverage in general,...
