This work was motivated by the recent explosion in popularity of media streaming to mobile devices. Wireless networks will always be bandwidth limited compared to fixed networks due to background noise, limited frequency spectrum, and varying degrees of network coverage and signal strength. Consequently, applications that need to move large amounts of data in a timely manner cannot simply assume that future networks will have sufficient bandwidth at all times. It is therefore important to make the applications themselves able to cope with varying degrees of connectivity. In order to understand the requirements of streaming in 3G mobile networks, we perform a large number of measurements in Telenor’s 3G network in and around Oslo. Using bandwidth traces from these field experiments, we compare commercial
