Location, Location, Location

In this article, the accuracy estimation of radio location techniques throughout ray-tracing-based propagation models has been discussed. Assuming as a reference scenario a 16-building Manhattan environment, some numerical results for 2-D location accuracy of some location techniques have been presented and discussed. It has clearly been shown that a site-specific simulation tool can easily account for NLOS conditions and multipath effects. Moreover, other error sources, such as thermal noise and measurement uncertainties, can be introduced if their statistics are known a priori. Therefore, validation and improvement of existing mobile location and tracking techniques, as well as the deployment of new and more accurate algorithms, can resort to deterministic propagation tools as a viable alternative to expensive field trials or approximate stochastic models.
