This system utilizes the integrated Bluetooth modules in any today's mobile phones to specify and display the location of the individuals in a certain building. The proposed system aim for location tracking/monitoring and marketing applications for whom want to locate individuals carrying mobile phones and advertise products and services. It is an integrated embedded and desktop system that helps the user to get the location of customers/inhabitants/employee within a certain region. The system is composed of a Server Module which is a java application that runs over desktop PC and is used to display the locations of the nearby mobile phones and send location based advertising message. This paper is aimed also to enhance the system positioning estimation accuracy by choosing the suitable number of neurons used in the neural network. � 2016 IEEE.EnglishAccuracyCustomersMobile phonesNeuronsObjectsServicesBluetoothCellular telephonesJava programming languageLocationMarketingMobile devicesMobile phonesNeural networksNeuronsTelephone setsTracking (position)AccuracyCustomersDesign and implementationsIndoor location trackingLocation-based advertisingMarketing applicationObjectsServicesCellular telephone systemsConference Paperhttps://doi.org/10.1109/ICEEOT.2016.7754772
