INDOOR LOCATION SENSING USING RADIO FREQUENCY NETWORK

This report discusses the activities in this project. An indoor location sensing system
using radio frequency network will be produced by using the triangulation method,
where signal strengths received will be used to determine the coordinates of objects
tracked. The benefit of this project is that it provides a foundation in the basic of
locating objects in a closed area. The flowchart for the main program and hence, the
programming of the calculations algorithm has been done and tested using user
simulated digital control input. The transmitter and receiver circuits have been
constructed and tested. However, no solid results could beobtained as no signals are
detected by the DAQ system using LabVIEW. There are several problems when
interfacing the circuits with the DAQ board but it is rectified soon after. Thus the
possible problems could be due to the use of unsuitable wire and antennas.
Nevertheless, this project will be continued until concrete results are obtained to meet
the objectives ofthis project, to bepresented during thefinal presentation.
