Most 3G operators offer this technology in its network. The main use of the service is Internet access with higher bandwidth and lower latency. This allows surf, download email, music and video faster. The operators have approached the service as a mobile access to broadband Internet for laptops. The main goal of HSDPA is to achieve a higher bandwidth. Compatibility is critical, so designers used an evolutionary philosophy HSDPA. HSDPA is basically equal to the UMTS Release 99 (R99), with the addition of an entity of repetition / scheduling in the Node-B that resides below the control layer R99 medium access (MAC).

HSDPA takes WCDMA networks to their full potential in providing broadband services through an increase in cellular data capability, with throughput higher. In the same way that UMTS increases the spectral efficiency compared to GPRS, HSDPA increases the spectral efficiency compared to WCDMA. The spectral efficiency and increased speeds not only enable new classes of applications, but also allows the network to be used simultaneously by a larger number of users; HSDPA provides three to four times more capacity than WCDMA. As for the interface of real-time applications such as video and games among multiple players upgrade to WCDMA technology to shorten the latency of the network (estimated at less than 100 ms), thus providing better response times.
