3GPP Release 5 HSDPA Measurements

This paper presents measurement results for 3GPP Release 5 high speed downlink packet access (HSDPA). The results have been obtained in the laboratory and in the field measurements during 2005. The measurements include peak throughput, link adaptation performance, latency, multiuser capacity, mobility and drive test throughput measurements. The results show good agreement with the simulations. The median throughput beyond 1 Mbps and latency below 100 ms have been achieved with the first phase HSDPA equipment in the field

Big Data Analytics for 4.9G and 5G Mobile Network Optimization

Smartphones and other devices connected to a mobile network typically create billions of measurement samples every day. Those measurements are currently used for instantaneous resource allocation and link adaptation. There is much room for using the measurements also for network optimization with big data analytics. The measurements give valuable insight into the service quality experienced by devices in their locations. This paper illustrates how machine learning algorithms can be applied to identify main interference issues in mobile networks. Subsequent optimization can then lead to lower interference levels, enhanced user throughputs and improved success rates.
