Аннотация
Although third generation cellular networks are being deployed in many countries, rigorous measurement studies from public networks have yet to be published. After extensive experimentation, we collect measurements from a commercial WCDMA 3G/UMTS network and observe that the goodput of the first of a series of back-to-back transfers is consistently below par. We compare these results with those obtained from an all-wired network and show that 3G signaling plays an important, albeit detrimental role in end-user goodput. Finally, we illustrate that near-nominal goodput is realizable for large payloads only.
