ULAND® is an IR-UWB system based on two identical transceivers capable of establishing a low data rate bidirectional communication and, at the same time, precisely measuring the distance between them. Its main objectives are robust communications against multipath even in NLOS environments, low data rates in the order of some kilobits per second, ranges up to 100m and a ranging precision under 30cm. ULAND® operates in the band from 6GHz to 8.5GHz and complies with regulations on the transmitted power in Europe and U.S.A. This system is intended for high precision ranging and robust communications in very harsh environments applications rather than low power and low complexity applications addressed by the 802.15.4a standard.  This is the reason why all the 2.5GHz available bandwidth is used and a quite complex receiver front-end architecture based on a filter bank is implemented. Apart of demonstrating the capabilities of UWB technology, ULAND® also provides a development platform to test different communication protocols, different detection, synchronization and TOA estimation algorithms and different frame structures, among other things.      

The ULAND project was awarded a grant from the INNOCASH program of FECYT in 2009. The objective of this program is to provide funding for the industrialization of research projects and prototypes, and appears in the Escaparate Tecnológico of FECYT,  http://www.innocash.es/publico/FormProyectosPublico.aspx?filtro=Telecomunicaciones&idioma=sp
