The authors compare Web traffic characteristics of mobile-versus fixed-access end-hosts, where herein the term "Mobile" refers to access via cell towers, using for example the 3G/UMTS standard, and the term "Fixed" includes Wi-Fi access. It is well-known that connection speeds are in general slower over mobile-access networks, and also that often there is higher packet loss. They were curious whether this leads mobile-access users to have smaller connections. They examined the bytes-per-connection and packet loss based on packet retransmissions from a sampling of logs from servers of Akamai Technologies. They obtained 149 million connections, across 51 countries. The mean bytes-per-connection was typically larger for fixed-access: for two-thirds of the countries, it was at least one-third larger.
