Because of rapidly growing subscriber populations, advances in cellular communication technology, increasingly capable user terminals, and the expanding range of mobile applications, cellular networks have experienced a significant increase in data traffic. Smartphone traffic contributes a considerable amount to Internet traffic. The increasing popularity of smartphones in recent reports suggests that smartphone traffic has been growing 10 times faster than traffic generated from fixed networks. Understanding the characteristics of this traffic is important for network design, traffic modeling, resource planning and network control. This paper presents an overview of the methodology for collecting data using smartphone logging and discusses traffic characteristics from some recent researches. The main goal is to explore some important issues related to smartphone traffic in order to prepare for further, deeper analysis.
