Environmental factors have a strong impact on the satisfaction of mobile users. Thus, estimating context session is key to evaluating end-user experience in network management. Such mainly defined by user location. In most cases, location derived from measurements absence handset measurements. Unfortunately, current geolocation techniques do not enough accuracy detect if was indoor or outdoor. this paper, data-driven statistical model proposed cellular connection originated an based traffic...
With the arrival of 5G, Fixed Wireless Access, which aims at providing households with broadband internet access using mobile technology, has become a relevant use case. Current greenfield design techniques are not optimal since they target optimizing radiofrequency configuration for whole household, sometimes expense other households. However, only spot where to install antenna customer premises equipment is enough Access networks. This letter presents an enhancement automatic methodology...
For network planning and optimization purposes, mobile operators make use of Key Performance Indicators (KPIs), computed from Measurements (PMs), to determine whether performance needs be improved. In current networks, PMs, therefore KPIs, suffer lack precision due an insufficient temporal and/or spatial granularity. this work, automatic method, based on data traces, is proposed improve the accuracy radio utilization measurements collected in a Long-Term Evolution (LTE) network. The method’s...
Small cell systems are a cost-effective solution to provide adequate coverage inside buildings. Nonetheless, the addition of any indoor site requires evaluating trade-off between and capacity gain provided by new its monetary cost. In this paper, automatic selection algorithm based on clustering techniques is presented. The calculates number antennas, radio heads, baseband units needed for area under study. Then, groups several heads different buildings in single pooled unit, reducing...
In cellular networks, spectral efficiency is a key parameter when designing network infrastructure. Despite the existence of theoretical model for this parameter, experience shows that real influenced by multiple factors greatly vary in space and time are difficult to characterize. paper, an automatic method deriving curves Long Term Evolution (LTE) system on per-cell basis proposed. The based trace processing tool makes most detailed performance measurements collected base stations....
