Book excerpt: Radio Frequency Technologies (RFID) are experiencing rapid development and business, retail, manufacturing and healthcare are the major application areas benefiting from it. We describe and analyze an algorithm which helps in tracking of medical equipment and personnel and patients in a Trauma Bay. We adapt the Read Count algorithm to be used at multiple attenuation levels as a localization technique. The input parameter to the algorithm is the read count value which gives a measure of number of times the back-scattered radio frequencies from passive tags has been received by the antenna. Special attention has to be given to the placement of antennas to get the optimum result. The detection of multiple tags and human occlusion are two major concerns which we have tried to solve by suing multiple horizontal antennas along with 1 vertical antenna. We have discussed the results and analysis of such a configuration and accordingly given a conclusion. The problems associated with the configuration have also been discussed which can form part of future work.
