During the last two decades, the world of the mobile communications grew a lot, as a
consequence of the increasing necessity of people to communicate. Now, the mobile
communications still need to improve for satisfies the user demands.
The new enhancement of UMTS in concrete HSDPA and HSUPA is one of these
improvements that the society needs. HSDPA and HSUPA which together are called
HSPA, give to the users higher data rates in downlink and uplink. The higher data rates
permit to the operators give more different types of services and at the same time with
better quality. As a result, people can do several new applications with their mobile
terminals like applications that before a computer and internet connection were
required, now it is possible to do directly with the mobile terminal.
This thesis consists in study these new technologies denominated HSDPA and HSUPA
and thus know better the last tendencies in the mobile communications. Also it has a
roughly idea about the future tendencies
