HSDPA technology (High Speed Downlink Packet Access), also known as 3.5G, 3G + or 3G turbo, is the optimization of spectral technology UMTS / WCDMA , including the specification of 3GPP Release 5 and consists of a new shared channel on the link downlink (downlink) that significantly improves the maximum data transfer rates drop and can be reached up to 14 Mbps (1.8, 3.6, 7.2 and 14.4 Mbps). It supports throughput rates of close to 1 Mbps average. Today, technology is also available HS U PA , with upload speeds of up to 5.8 Mbps, and HSPA + with speeds of up to 84 Mbps downstream and 22 Mbps on the rise.
Is the evolution of third generation (3G) technology phone , called 3.5G , and is considered the first step before the fourth generation (4G), the future integration of networks. Is currently developing the specification 3.9G before the launch of 4G .
It is fully compatible with WCDMA reverse and rich media applications developed to work with WCDMA HSDPA. Most vendors provide support for HSDPA UMTS.
HSUPA (High-Speed Uplink Packet Access or Access upward packets at high speed) is a data access protocol for networks of mobile high transfer rate of increase (up to 7.2 Mbit / s ).Branded as Generation 3.75 (3.75G) or 3.5G Plus is an evolution of HSDPA (High-Speed Downlink Packet Access, declining access to high-speed packages, named locally as 3.5G). The solution initially boost HSUPA uplink UMTS / WCDMA (3G).HSUPA is defined in Universal Mobile Telecommunications System Release 6 standard published by 3GPP ( www.3GPP.org ) as a technology that offers a substantial improvement in speed for the uphill, from the terminal to the network.HSDPA and HSUPA offer high voice and data services, and will create a large market for services IP mobile multimedia. HSUPA data applications enhance advanced person-to person, with larger and more symmetric data rates, such as e-mail on mobile and real-time game with another player. Traditional business applications along with many consumer applications will benefit from the increase in connection speed.
What your mobile operator offers?
Companies often use a very technical terms and nice to sell the bike. That if Vodafone has coverage HSUPA, 3.5G Movistar offers but really what is and to serve all those buzzwords?Currently there are four operators in Spain that are licensed for 3G or UMTS: Movistar, Vodafone, Orange and Telstra. From that 3G technologies have been developed that enable ever faster browsing from your mobile or from a computer connected Through a modem.
Technology and speed per operator
Right now the best rate offered is Vodafone HSPA + coverage areas. This technology, with the appropriate phone modem or, in theory allows browsing to 21.6 Mbps downstream and upstream 5.76. This rate is available for various mobile Internet products while others will be the download speed of 7.2 Mbps using HSDPA technology.
Movistar offers a speed of 10 Mbps downstream with 2 rise in Internet Flatrate Maxi while the remainder of price is reduced speed to HSDPA (7.2 down) or even 3 Mbps.
For most of the Orange mobile internet rates operate on HSDPA so the download speed is 7.2 Mbps. Yoigo itself also has HSDPA coverage however their speed limit is lowered by 3.2 Mbps. In areas without coverage own customers of this operator can use the network to Movistar.
Knowing the speed offered by each operator (MVNO will always depend on the operator to provide them with coverage) the question is how fast I need to surf the Internet and the answer is not simple, since it depends on how it is used to connection.
To navigate from the phone with a theoretical speed of 3.2 Mbps HSDPA gives it would be more than enough but to travel through a computer would recommend a higher speed, at least for the 7.2 Mbps offered by three major operators.
Especially because of the theory to reality is a long way and as Telstra said in its website with its 3.2 Mbps "normal average speed of such connections is 0.8 - 1.5 Mbps. This information is not I usually give the operators but we are well Clarita. "
To all this we should also add that we cover (you have links to the cover of each operator in the right menu of this website) and the compatibility of our phone or modem with the various technologies that provide more speed.
