Experimental Analysis of a Node B Coverage Based on the CPICH and Ec/Io Values

This paper presents experimental results of a coverage analysis in a WCDMA network using the 850 MHz band; an urban electromagnetic propagation environment is considered. Obtained coverage estimation maps are based on Krige statistical method of interpolation. Key performance parameters used in this work are the CPICH and Ec. The results could be used to identify problems and help to optimize cell coverage and capacity in a given service area.

Krige Method Application for the Coverage Analysis of a Node-B in a WCDMA Network

This paper shows the procedure and application of the Krige Method (or Kriging) for the analysis of the power level radiated by a Base Station (also called Node B), through a group of samples of this power level, measured at different positions and distances. These samples were obtained using an spectrum analyzer, which will allow to have georeferenced measurements, to implement the interpolation process and generate coverage maps, making possible to know the power level distribution and therefore understand the behavior and performance of the Node B.

A Geographic Information System Applied to Coverage Maps of 3G Cellular Communications Networks

This paper shows the procedure to obtain a continuous coverage map based on a collection of power meas- urements using a Geographic Information System, through satellite photographs of the Professional Unit Adolfo Lopez Mateos, and a group of punctual samples of the power of the Common Pilot Channel (CPICH); which is used to estimate the radio communications channel conditions, taken at different positions and dis- tances. These samples were taken using specialized equipment to obtain georeferenced measurements, and by a technique of statistical prediction, as the Krige Method, generate continuous coverage maps, making it possible to know the distribution of power, and therefore understanding the behavior and configuration of a Base Station, which in third generation cellular systems is also called Node B.

Performance Characterization Parameters on Voice and Data Transmission in Mobile Terminals to Cellular Networks

This work presents the experimental results related to performance measurements in GSM and GPRS cellular data networks. Two Mobile Terminals were used, in order to take place the scenario. Power Level, Power vs. Time, Modulation Analysis, Modulation Spectrum, (BER) Bit Error Rate and Throughput were considered in this analysis.
