On-Building announcement system using bluetooth
Trisha Ghosh, Sneha Tiwari · 2017
In this paper, we have discussed the experiments performed by us on Bluetooth technology. These experiments are divided into sections that describe the extension of the limitation of Bluetooth range. Section A: Here we are showing a piconet consisting of four slaves and one master in a Bluetooth ad-hoc network ranging 200meters. Section B: Three piconets with four slaves each and slave of one piconet is the master of the other preceding piconets and the communication range is of 400 meters. Section C: Ten piconets each consisting of seven slaves and one master i.e. the maximum number of devices that can be connected within one piconet, is shown with a range of around 1000 meters and with same configuration as above. We have calculated the throughput for each section and the simulation of each configuration has been done on QualNet software of version 6.1. From the experiments we have proved that the range of Bluetooth can be extended above 100 meters. Thus by our experimentations, we have designed an announcement system using Bluetooth in which the database of the announcement system is maintained for anytime access.
