Augmenting Mobile 3G Using WiFi: Measurement, System Design, and Implementation

Free registration required

Executive Summary

This paper investigates if WiFi access can be used to augment 3G capacity. To understand the feasibility of 3G augmentation, the authors conduct a detailed study of 3G and WiFi access from moving vehicles, in three different cities. The authors find that the average 3G and WiFi availability across the testbeds is 87% and 11%, respectively. The authors also find that, unlike stationary environments, WiFi throughput is lower than 3G throughput in mobile environments, and WiFi loss rates are higher.
