Location-aided planning in mobile networks: Trial results

Location-Aided Planning (LAP) technique provides possibility to use mobile phone measurements for monitoring network performance and traffic conditions. It enables detection of problem areas in the network, creation of alternative network plans for various traffic conditions as well as tuning and validation of propagation models with measurement data retrieved from the network. The paper reports results of a trial validating the LAP concept performed in standard GSM 1800 network in the frame of the EU IST project Cellular Network Optimization Based on Mobile Location (CELLO) [1]. During the trial, the accuracy of four selected location methods was evaluated. The measurements done during the trial were additionally used for assessment of the propagation model based on the well-known Okumura–Hata model with some corrections due to diffraction, building and land cover effects.
