INDOOR POSITIONING WIFI DI SMARTPHONE ANDROID
ABSTRACT: Ease of access and
availability of wireless technology and mobile computing has given rise to new
opportunities in the development of mobile applications whose goal is to make
people’s lives easier. Mobile technology today not only as a means of
communication, but it has become as a navigation tool. The navigation system
today many are needed for specific needs. Indoor Positioning System is a
solution for determining the location of an object or a person who resides in
the building which uses radio waves, magnetic fields, acoustic signals or other
sensors capable of transmitting information via mobile devices. The method will
be used to determine the position using the received signal strength indicator
(RSSI). RSSI is a measurement of the power received by a wireless device. RSSI
measurements have some variation due to the influence of fading or shawoding.
Radio wave propagation in free space to follow the rules Friis equation and
path loss is proportional to ,, where d
is the distance between source and receiver. The test results and analysis that
indoor positioning wifi on smartphone androidusing RSSI measurements can
produce an object position which is almost the average of all experiments close
to perfect, although each trial is still having problems error. However, the
error that occurs is still acceptable.
