A low cost, low power UWB based sensor network

This paper presents a sensor network with low power, low cost devices based on UWB technology employing TDMA. The low data rate network (of the order of 1 kbs-100 kbps per user) is described which also offers good location and tracking capabilities. The UWB tags consist of low power, low-cost, low-complexity transceivers which operate in conjunction with a number of fixed sensor nodes which calculate the tag position. This paper presents the system concept, UWB transceiver and performance in a multipath environment. Location and tracking is not specifically dealt with in this paper.
