Nowadays the accuracy of existing location methods in networks is insufficient, particularly in emergency calls. Modification of chosen algorithm parameters leads to improvement of the accuracy of an MS position estimation. The most important parameter, which decides on location accuracy of an MS, is a true value of distance between a mobile station and a base station (BS). The improvement of this...
Two efficiency methods for a location service (LCS) by use the wideband code division multiple access (WCDMA) interface, in the frequency division duplex (FDD) mode, are outlined. The LCS in the WCDMA/FDD technique is based on the actual relative time differences (RTDs) between base stations of the monitoring cellular network. The proposed methods enable calculation of the geographical position of...
In this paper the unique coastal cellular distress system (CCDS), based on a cellular phone network was proposed. The concept, functional properties and services of this system were described. The problem of the location service (LCS) at sea was presented. The geographical location accuracy of a mobile phone in a coastal sea area is analysed. Special measurement system and software application, designed...
In this paper the unique coastal cellular distress system (CCDS), based on a cellular phone network was proposed. The concept and functional properties of the system were described. The problem of calculation of the geographical position of a mobile phone in a coastal sea zone was analysed. The geographical location accuracy of the mobile phone in a coastal sea area was investigated. The measurement...
