This paper explores the tradeoffs and limitations inherent to 3G data communications, by analyzing the performance of 1xEV-DO, a representative 3G technology. It will then compare this to what is achievable with Wi-Fi (802.11b) using the Tropos cellular mesh. The analysis of this paper can be generalized to other 3G technologies, such as the WCDMA, and the main conclusions do not differ since the performance of 1xEV-DO and WCDMA are within 10-20% of each other (see "Comparison of services with 1xEV-DO, WCDMA and cdma2000" in [AGILENT]).
