Techopedia Explains Enhanced Dedicated Channel

In HSUPA, an enhanced dedicated channel allows for lower latency and rapid transmission, decreasing end-user delays in the system. Different types of E-DCH include Enhanced Dedicated Physical Data Channel and Enhanced Dedicated Physical Control Channel.

The HSUPA protocol was designed by the 3rd-Generation Partnership Project including telecom carriers like AT&T and others around the country. By innovating for HSUPA and other protocols, these groups improve the ways that smartphones and mobile devices work in the digital age.
