DC-HSDPA (Dual Carrier or Dual Cell High-Speed Downlink Packet Access) - definition


HSDPA technology has its limits and to further enhance its performance, the DC-HSDPA technology was introduced.

An advanced HSDPA+ network can theoretically support up to 28 Mbit/s and 42 Mbit/s with a single 5 MHz carrier. Doubling the bandwidth to 10MHz results in theoretically, double the sustained data rate.
