With the recent advent of 4G LTE networks, there has been increasing interest to better understand the performance and power characteristics, compared with 3G/WiFi networks. In this paper, the authors take one of the first steps in this direction. Using a publicly deployed tool they designed for Android called 4GTest attracting more than 3000 users within 2 months and extensive local experiments, they study the network performance of LTE networks and compare with other types of mobile networks. They observe LTE generally has significantly higher downlink and uplink throughput than 3G and even WiFi, with a median value of 13Mbps and 6Mbps, respectively.
