Transmission throughput is less than expected for a 3G WWAN data card in Windows Vista
You use a 3G wireless wide area network (WWAN) data card on a Windows Vista-based computer. The WWAN data card uses a connection that only receives data. However, you may find that the throughput is much less than the throughput of the same 3G WWAN data card when you use it on a Microsoft Windows XP-based computer.
