Experimental wireless ultra wideband sensor network for data collection

In this paper the experimental UWB wireless sensor data collection network is presented. The simulation of reception algorithm was performed using Matlab. The number of UWB transmitters was 4. Packets of different transmitters had different formats. It is shown that the increasing number of repetitions on the physical layer allows achieving BER performance close to theoretical limit. The increasing number of repetitions also provides increased probability of packet delivery. The length of preamble is 1000 elements and is defined by the requirements of minimization of BER and maximization of probability of packet delivery. Functional tests conducted for the worst case of simultaneous operation of all transmitters.
