This paper presents verifications for UMTS coverage and capacity in a live network using planning and performance tools applied to a real-world operational UMTS network. Case study results are presented and followed by comparisons between coverage predictions, capacity simulations, field measurements and system statistics. Tuned propagation models based on(More)
The benefits of horizontal beamforming in cellular networks are well unterstood, and the technology is already used in commercial products. Recently, vertical beamforming (basically a user specific downtilt (DT)) receives a lot of attention as well. However, available channel models do not allow for an accurate simulation of this transmission scheme. This(More)
It is assumed that stability and maintainability are relating to each other. We attempt to verify and validate this assumption in object-oriented paradigm. Two candidate metrics were chosen, one for stability and one for maintainability. CSM is used in stability due to its high accuracy and wide coverage. MI was chosen for maintainability due to its(More)
and hosti es.2013.0 Abstract In oil reservoirs about 40% of the original oil in place is produced and the rest remains as residual oil after primary and secondary oil recovery due to geological and physical factors. Additional oil can be mobilized by applying some improved oil recovery methods. However, there is no universal IOR method to be implemented in(More)
Empirical validation of software metrics suites to predict fault proneness in object-oriented (OO) components is essential to ensure their accuracy in practical industrial. In this paper, we empirically validate the Chidamber and Kemerer (CK) metrics suite metrics for their ability to predict software quality in terms of fault-proneness: we explore the(More)
Coordinated Multi-Point (CoMP) Multiple Input Multiple Output (MIMO) transmission improves user's coverage and data throughput particularly on the cell edges. To make full advantage of CoMP, radio planning tools need very accurate models that fully capture the MIMO channels characteristics. This paper presents detailed modeling and analysis of an uplink(More)
