We'd like to distinguish between peak and normal data rates when evaluating mobile data speeds. The height velocity is the utmost speed the mobile network can technically enable. In distinction, the common velocity is exactly what a user frequently gets once the sign has travelled through the foundation station to multiple consumer devices simultaneously. The peak data rates with HSDPA are 14.four Mbps for downloads, and the peak data rates with HSUPA are 5.
