Development of simulation model & estimated accuracy for location determination technology (LDT) using enhanced observed time difference (E-OTD) / Muhd Zulfadli Ishammudin

Location related services are described as the next revolution on services and functionality in the mobile network. Location technology will help the operator to estimate the location of a mobile station in the network. But different location services require different accuracy of the location estim...
