HSUPA
HSUPA (High-Speed Uplink Packet Access) : A data access protocol for mobile-phone networks that aims to increase upload speeds of WCDMA networks. As they do with HSDPA, some people refer to HSUPA as 3.5G or 4G mobile Internet. While most Internet applications, such as Web surfing, music and video downloads, and e-mail, rely heavily on downlink speeds, applications such as video conferencing also require fast upload speeds. The specifications for HSUPA are still under development.
