Recent technological advances have resulted in a dramatic change in the market shares of cellular mobile devices. However, little is known about the impact of these changes on the landscape of cellular network traffic. Using anonymized traces from one million cellular subscribers, the authors conduct a comparative study of the usage characteristics of three different types of mobile devices: feature phones, air cards, and smart phones. Their study covers three aspects: traffic volume in terms of data, voice, and short messages and corresponding temporal fluctuations, applications breakdown in data access, and the presence of malicious traffic.
