What does Enhanced Dedicated Channel (E-DCH) 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 (E-DCH)
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.
