RFTrack: TVWS Spectrum Measurements using Android Phones

Published: 01 December 2015 Publication History

Abstract

Despite successful trials in several Developing Countries, TVWS has not gained the amount of attention that it deserves. One of the reasons is the lack of awareness by both the general public and the spectrum regulators about the abundance of idle spectrum. Traditionally, spectrum measurements required expensive instruments and considerable operator's expertise. This has changed with the emergence of low cost spectrum analyzers that are also easier to operate. In this paper we present an Android application called RFTrack that measures spectrum using a low-cost spectrum analyzer and geo-tags the data using the phone's GPS. Data is stored in the internal memory. Once an Internet connection is available, the program sends data to a server that presents the results in an easy-to-understand way. After having performed some measurement campaigns with this set up, we believe that this is a useful tool to demonstrate the existence of significant swats of of underutilized spectrum, especially in rural areas of developing countries.
