User-perceived application-level performance is very important to the adoption and success of 3G wireless services and infrastructure. This paper illustrates the end-to-end application performance when connecting through a CDMA-1XRTT network and compares the performance to that of a dialup connection. The results show that the application performance in CDMA-1XRTT may depend on the application traffic behavior. While many applications perform quite well in CDMA-1XRTT, others such as Microsoft Outlook perform below expectation and may even be slower than a dialup connection. This paper proposes an enhanced application sensitive scheduling algorithm to improve the performance of such applications. The enhanced algorithm also provides additional benefits for applications with similar behavior as Outlook. These include additional channel code availability and channel switching process reduction by as much as 60%.
