What does HSPA
HSPA terminology and definition
What is HSPA and where does it come from?
HSPA is made up of the parts HSDPA and HSUPA together. Where HSUPA (High speed uplink packet access) the bandwidth for upstream increased and HSDPA (High speed downlink packet access) increases the bandwidth in the downstream.
HSDPA and HSUPA are implemented separately, even if they have a similar structure. However, if both components are used together, one speaks of HSPA for short. The current transmission speed of HSPA is up to 5.76 Mbit / s im Upstream and 14.4 Mbit / s in Downstream. With the expansion from HSPA to HSPA + and with the new fourth-generation LTE cellular standard, even higher bandwidths are possible. So that the network operators can use HSPA, the base stations must be upgraded accordingly by the network operators.
The costs for expanding existing UMTS base stations to HSPA are far lower than the costs for setting up the infrastructure for UMTS. These are improvements through which the capacity of the UMTS network can be better used. For example, this happens through different priorities of the user in connection with the transmission method or the restriction of the Data volume for correcting errors in connections with optimal quality.
The terminals such as Tablet, Smartphone or Surf stick must of course support the HSPA standard. Upgrading the software for the end devices is unfortunately not possible, but most end devices are now suitable for HSPA. Downstream is in every way the more important component of virtually all broadband activities. For this reason, network operators and cell phone manufacturers only considered upgrading for HSPA in the past. Even today, cell phones are still appearing on the market in which only the turbo is installed for.
The history of the HSPA
This is closely related to advances in development in mobile communications technology mobile internet. Already in the 90s there was the possibility to use the GSM network (Second generation data transmission standard - 2G) to access the Internet. Initially, this was only possible as a CSD data connection with a low data speed. However, the introduction of the GSM upgrades HSCSD GPRS and EDGE provided a remedy and delighted users with higher speeds.
The developers achieved the breakthrough with fast and stable mobile internet usage in 2002 with UMTS. In 2006 followed on UMTS based on HSDPA and HSUPA, usually also referred to as HSDA for short. At that time, the download speed was up to 7.2 Mbit / s and up to 1.45 Mbit / s with the Upload reached. Convinced of the stability and speed of data transmission, the mobile phone providers began to convert their mobile phone networks to UMTS in 2007 and shortly afterwards to HSPA, based on the UMTS network.
Despite the good technical equipment of most common cell phones, HSPA was not a good replacement for the home PC or notebook. Due to the small display size and quality as well as the underdeveloped ergonomics of the mobile phones, only a few end users used the function of the Internet for on the go. In addition, it was at that time Area coverage of the HSPA network in Germany is so low that most end users limited the mobile use of HSPA in planes, trains and cars to sending and receiving e-mails. Even today, HSPA is still not widespread in Germany.
In spite of everything, in communication technology and in all other areas as well, research is always being carried out for improvements. The further development of the HSPA is led under the name HSPA + and there are Speeds of more than 20 Mbit / s planned.
HSPA and the consequences
Until recently there was still that DSL connection an indispensable part for anyone who wanted to surf the Internet quickly. However, thanks to sophisticated HSPA technology, new possibilities and paths open up for every Internet user. Due to the speed achieved, the mobile Internet is a good alternative to the conventional Internet connection and therefore a serious competitor for the fixed network. Due to the constant improvement in availability and the ever-increasing speed Data transfer The number of those who use mobile Internet access not only on tablets or smartphones, but also on laptops and PCs is also increasing.
The large network operators get in this area from so-called Resellerswho are cheap in the field of mobile internet HSPA flat rates to offer. Due to the fierce competition, users benefit from the lower prices. By constantly expanding the data network, HSPA has greatly improved the usability of the mobile Internet. Together with the lower prices, the mobile Internet is spreading more and more, because nowadays the possibility of surfing the net anywhere, both professionally and privately, opens up new avenues in every respect.
HSPA and the future
However, HSPA is not only used in mobile devices. Even today there are areas in which no DSL line or VDSL line is available. There are HSPA routers to give these people access to the Internet. These HSPA router are routers that receive HSPA via the radio frequency and thus enable access to the Internet.
Since progress never stands still, the fourth generation of the data transmission standard (4G) is already in the starting blocks. her name is LTE and is also an extension of the UMTS network with even faster packet data transfer.
