Wireless CDMA: Data throughput, device throughput is a little lower than expected, how to resolve?
TestDrive II - apply to all the versions
Please check following items:
1x bi-directional FTP Data Throughput tests are not supported with a Windows XP (Client PC) + Windows 2008 Server (Application Server) combination.
Prior to test, perform TestDrive II calibration. This can be done through TestDrive II GUI, click Execute-Calibration, choose Calibrate All.
During test, check UE receive power and Ior/Ioc via QXDM, ensure receive power and Ior/Ioc are same as required by test. e.g. if test (IOR=-101dBm / IOC=-105dBm), ensure receive power is 101dBm, Ior/Ioc is 4dB.
If not these two values, maybe system need hardware calibration.
Try a data card. Data card has better data throughput performace than a handset phone.
Use a shield box, especially when wireless channel condition is bad. e.g. IOR is low, fading and noise is enabled.
