On the feasibility of bandwidth estimation in 1x EVDO networks

The problem of fast bandwidth estimation has been extensively studied in the wired Internet and recently, in 802.11 wireless networks; however, no tool has been reported so far in the literature for cellular networks. Although cellular networks share some common characteristics with 802.11 WLANs, they also have many differences which make it unclear whether tools developed for 802.11 WLANs can also be used in cellular networks. This paper presents the first study of the feasibility of fast bandwidth estimation in 3G networks. We studied the applicability of a state-of-the-art probe-based tool for 802.11 WLANs on a commercial 1x EVDO network. Our results show that bandwidth estimation using a probe-based tool is very difficult in EVDO networks, due to the short-scale dynamics in this type of networks.
