High Speed Packet Access or high speed packet access, is a telecommunications technology known as 3.5G, third generation (3G). it has been designed with the aim of improving what is UTMS technology (Universal Mobile Telecommunications System).
That is how HSPA works through two specific protocols that are used in tandem, which help it to function smoothly. high speed. All of this has been converted into an improved version that allows extend and improve the performance of mobile company networks.
If you still do not know completely this HSPA technology, then here we are going to explain what it is about, its main operation and what is its role in telecommunications, To do this, follow in detail everything that we will explain in this post.
What is HSPA and what is this technology for in telecommunications?
Basically HSPA it is an update of what it is 3G UMTS which enables provide higher data speed being higher on both uplinks and downlinks. All this with the aim of improving performance and thus provide a better customer service.
Therefore, all of this was designed to be able to increase the capacity of Internet connectivity from smartphones in 3G, which are based on UMTS and WCDMA. Taking into account that 3G UMTS was the one who allowed mobile communications they will move from a voice-centric system to a data-centric system.
But nevertheless, 3G UMTS speeds Weren’t quite enough for what it is browsing and downloading images and videos, that is why the need for improve this technology with HSPA. As already mentioned above it works with two specific protocols, as it is HSDPA which are the high-speed downlink packet accesses and the HSUPA, which are high speed uplink packets.
In the same way, this kind of HSPA networks are able to offer a 14.4 megabytes per second maximum throughput. All this has undoubtedly made it a Improved version that allows to provide a faster Internet browsing speed from mobile.
Evolution of HSPA What are all the versions and improvements of this technology that exist?
Like all technology, since the birth of HSPA different versions and improvements have been developed with the aim of keeping this system updated and capable of offer very good performance speeds.
That is why below we are going to explain each of these versions and what have been the improvements of each one of them with respect to the previous one:
- HSPA: As already mentioned, HSPA was the first technology used with the aim of improve internet connections from mobile, thus improving those of the UMTS standard. Since then, HSPA has been constantly evolving thanks to what has been the 3GPP standardization consortium, who constantly allows to perform techniques that serve to improve standard.
- HSDPA: The second version that comes to continue improving all this Internet connectivity by telecommunications ends up being HSDPA, which breaks the limit 384 Kbps of UTMS, thus providing a really good speed, considering that the most frequent speeds in the case of Spain they are 3.6 Mbps and 7.2 Mbps.
- HSUPA: With the aim of continuing to improve all this, it ends up developing HSUPA, this comes with the aim of further improve upload speed up to 5.7 Mbps and in that way to be able reduce connection latency. In the case of Spain the most common speeds of this type are 1.4 Mbps being able to arrive at 2 Mbps upload.
- HSPA +: After all this is developing HSPA + or HSPA Evolved as it is also known, this standard allows increase still plus speed modulating data with 64QAM only in cases where the signal is really good. As usual, 64 QAM modulation carries more information with the same resources radioelectric.
This makes it possible to reach reach speeds up to 28 Mbps download and at least 11.5 Mbps upload.
- HSPA + MIMO: Finally, we find what is HSPA + Mime, what is also called as the second phase of HSPA +. If HSPA + use MIMO may transmit through several signals in parallel thus achieving a speed of up to 42 Mbps. Something that allows further improve performance in telecommunications connections.
How does HSPA improve the UMT of 3G networks? Main advantages
Basically HSPA was developed to become an improvement over to UMT standard with which they all work 3G networks. But in this case, the HSPA use more efficiently the radio spectrum that all the operators have assigned. This is how thanks to this technology users can improve the speeds and latency of data transfers offering like this better results in Internet browsing.
That is how the UMTS was more oriented towards the operation of switched circuits, this did not turn out to be quite adequate for package operations, since users required higher speeds that were not available to UMTS. Thus, HSPA was incorporated in many UMT networks so that these could operate better in the necessary applications.
All of this offers a great amount of benefits to users, one of them is that it allows them to have a better performance when using mobile connections. That is why here we present you the main advantages of this improvement in standards:
- Shorter Transmission Intervals (TTI): By having a Shorter TTI, significantly reduces round trip times, which allows improve adaptation to rapid channel variations. This can provide a reduction in latency.
- Using higher order modulation: In this case the 16QAM it’s used in the HSDPA downlink so that the data can be transmitted to a high speed, getting to be achieved speeds of up to 14 Mbps on these links. While the QPSK keep using in HSUPA uplinks where do they get maximum speeds of up to 5.8 Mbps.
- Using the link adaptation: When it is achieved adapt the link, you can maximize what is the use of the channel.
- Use of shared channel streaming: Power share resources allows them to be obtain higher levels of efficiency and which are integrated with data packets and IP concepts.
- A quick programming of node B: It allows what is the use of quick programming with adaptive and encoded modulation that allows the system to respond to radio channel conditions and interference, only on the downstream channel. In this way, data traffic can be accommodated so that it tends to be transported faster.
- Hybrid ARQ based on node B: This helps provide shorter round-trip times from reduced retransmission and at the same time allows add robustness to the system so that smooth combining of retransmissions is allowed.
- Costs reduction: In the case of operators, with the implementation of this technology it is possible to achieve reduction of costs per bit transported, and at the same time allows to obtain a increase in system capacity. Thus, as data traffic increases, operators increase data transmission revenues, This resulted in something very positive for these companies.
- It can be incorporated through software updates: Finally, we find another advantage of this technology, and is that HSPA can be incorporated into software updates on the system, which means that it not only offers excellent benefits to operators, but also users.
Terminals with HSPA In what type of equipment can we find this technology?
Not all devices have HSPA nowadays, that is why Here we are going to show you which are the terminals in which you can find this technology and thus begin to use it:
In the case of mobile devices, the large mobile phone companies already have various teams that include these capabilities as they are: HTC and HTC Touch Diamond, as well as Nokia that has models like N95. In the case of new 3G models that have been released also usually have including this technology in your system.
In the case of Spain exist four operators what offer this HSPA service in their mobile networks, in this case it is Movistar, Vodafone, Yoigo and Orange. This is how here We show you a comparative table between each of them and their respective speeds according to the service:
3.6 Mbps Yes 21.6 Mbps
7.2 Mbps 5.76 Mbps 42 Mbps
7.2 Mbps 5.76 Mbps 42 Mbps
14.4 Mbps 2 Mbps No
4G USB Skewers
Another way users can connect to an internet network is through USB modems. In general, each of them usually has a operator network and a specific speed. This is how they can currently be found these types of devices with HSPA technology, which provides better upload and download speeds to users.
Therefore, here we teach you the most common modems that you will find on the market with this type of technology:
3.6 Mbps or 7.2 Mbps 384 Kbps When using WCDMA upstream, high latency is generated.
