Uplink performance in 3G networks

3G networks penetration is increasing in China, particularly on mobile devices, but little is known about the performance in the country. In this paper, the WCDMA and CDMA´s uplink broadband performance was measured in Nanjing. Content of the measuring include throughput, packet loss, delay and receiving interval. Through testing, we can identify the relationship between uplink packet loss, delay and receiving interval with throughput. We observed that the maximum throughput values are quite away to the advertised throughput for both WCDMA and CDMA2000 uplink. Through multi-path test, we found that when using two-path with the same 3G will not interfere with each other within a certain transmission rate, but three-path will. Furthermore, different 3G cannot interfere with each other.
