  • HSDPA is a component of the 3G network but belongs to the high-speed packet access family, which is capable of higher performance. UMTS is a 3G communications technology that uses WCDMA and other variations therein.
  • HSDPA was first introduced in 2008, although UMTS was first in 1999.
  • Theoretically, UMTS can transfer data at a rate of 21 Mbit/s, whereas HSDPA can do so at a rate of up to 14.0 Mbit/s.
  • For UMTS to succeed, a new base station and frequency must be assigned, and a new transport layer channel must be developed and coupled with the WCDMA specification.
  • UMTS, a 3G cellular system designed for mobile devices, uses the HSDPA protocol.
  • In contrast to HSDPA, which attempts to make UMTS even more effective and quick, UMTS aims to provide the elements that make a network system.
  • HSDPA has a download speed of 42 Mbps, compared to 2 Mbps for UMTS.
  • HSDPA has an average download speed per user of 5 to 8 Mbps, compared to 384 kbps for UMTS.
