What Does Enhanced Dedicated Channel Mean?
Enhanced dedicated channel (E-DCH) is a particular resource used for the facilitation of High-Speed Uplink Packet Access (HSUPA), a protocol to create high uplink speeds for data packets in 3G systems. In HSUPA, these types of additional channels provide additional signaling capacity.
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.
