What does HSDPA mean? What does HSP mean?

The 3GPP has unveiled a new high-speed data transmission technology called High-Speed Downlink Packet Access (HSDPA).

3G (Super3G) and HSDPA are two different stages of 3G development. Super 3G is the stage of technology development in a few years, and HSDPA is being introduced to the market as the R5 version of WCDMA.

Since any new technology needs to go through a certain R&D and preparation period to achieve commercial use, the attention and research on ultra-3G has begun. As far as HSDPA is concerned, as the R5 version of WCDMA, it has the same architecture and hardware platform as WCDMA, and is fully mature from a technical point of view. Ericsson's WCDMA solution allows for a smooth evolution to HSDPA with only a software upgrade.

In addition, with the large-scale deployment of 3G and the accelerated growth of users, the demand for mobile broadband is also growing rapidly. HSDPA offers transmission rates comparable to XDSL and can support a range of mobile broadband applications, so it will have a very broad market. Ericsson expects HSDPA to be commercially available by the end of this year and to be widely deployed starting in 2006.

HSP refers toHeat shock proteins, the full name is heat shock proteins.

Heat shock proteins (HSPs) are proteins that range from bacteria to mammals.

A class of heat stress proteins is widely present. When an organism is exposed to high temperatures, it is synthesized by heat to protect the organism. Many heat shock proteins have molecular chaperones.

Activity. According to the size of the protein, heat shock proteins are divided into five categories.

Distribution:

Small molecule heat shock proteins have a molecular weight of 12-34 kd, and they are extremely widely distributed, from bacteria to human genomes.

There are genes for small molecule heat shock proteins.

Unlike other large molecules of heat shock proteins, small molecules of this group do not appear to be essential for cellular function. However, small molecule heat shock proteins have a variety of functions, including imparting heat tolerance to cells to resist high temperatures.

Acts as a molecular chaperone to prevent protein aggregation and fight normal cell death, thereby regulating the balance of cell survival and death. The minimum amount of small molecule heat shock proteins that can avoid substrate denaturation is related to both substrates and heat shock proteins (Rosalind et al.)., 1998)。

The full name of HSP in English is: heat shock protein, and the name in Chinese is:Heat shock proteins, which is an emergency reactive protein that can be induced by high temperature stress.

HSPs are chaperones.

In the process of protein post-translational modification, it plays a role in promoting the folding of polypeptide chains into native spatial conformations.

Currently, people are interested in eukaryotic cells.

The folding process of internal proteins is still poorly understood, and the knowledge about protein folding mainly comes from the study of protein folding in Escherichia coli, which includes the three groups of HSP70, HSP40 and GREE.

Basic Information. In 1987, Ikemura discovered Bacillus subtilis.

The folding of subtilisin requires the help of a propeptide. This class of propeptides is often located in signal peptides.

and mature polypeptides.

In the process of protein synthesis, the protein polypeptide chain mediated by it is synthesized one after the other and covalently bonded.

Ligation is necessary for the correct folding of mature polypeptides, and after the mature polypeptides complete folding, they are separated from the propeptide by hydrolysis. Shinde and Inouye refer to these propeptides as intramolecular chaperones.

Chaperones are a large group of proteins in the cell, a family of unrelated proteins that mediate the proper assembly of other proteins, but do not become components in the final functional structure themselves.

Differences between HSPA and HSPA+: different speeds, different performance, different technologies, and different network stability.

1. The speed is different.

HSPA+ is faster than HSPA. The highest downlink is 21Mbps, and most HSPA+ phones basically support the highest uplink speed and the maximum downlink speed of 21Mbps or 28Mbps.

2. The performance is different.

HSPA+ performs better than HSPA.

3. The technology is different.

HSPA+ is more technologically advanced than HSPA.

4. Network stability is different.

HSPA+ has a more stable network than HSPA.

HSPA stands for HSPA High-Speed Packet Access.

HSPA+ stands for High-Speed Packet Access+. Enhanced high-speed packet access technology is an enhanced version of HSPA.

HSPA's R99 and R4 systems can provide the highest uplink and downlink rates of 64Kbps and 384Kbps respectively, in order to compete with CDMA1XEV-DO, WCDMA has introduced HSDPA in the R5 specification and HSUPA in the R6 specification, and HS-DPA and HSUPA are collectively referred to as HSPA. HSDPA (High-Speed Downlink Packet Access) enables up to high speeds on the downlink. The performance of HSDPA has been optimized and improved through new adaptive modulation and coding, as well as the transfer of some radio interface control functions from the wireless network controller to the base station, enabling more efficient scheduling and faster retransmission.

HSUPA (High Speed Uplink Packet Access) enables high speeds in the uplink. More efficient uplink scheduling and faster retransmission control in the base station contribute to HSUPA's superior performance.

HSPA+, Evolved HSPA (aka: HSPA Evolution, HSPA+, i-HSPA, or Internet HSPA) is defined as 3GPP Release HSPA that provides HSPA data transfer rates of 42 Mbits downstream and 22 Mbits uplink, using MIMO technology and higher-speed modulation. HSPA+ is a downward evolution version of HSPPr6 and is a technology that enhances uplink and downlink capabilities.

From the perspective of standard definition, the downlink service channel of HSPA+ is HS-DSH, so the downlink terminal class is also called "HSDPA terminal class", of course, the "HSDPA terminal class" here is different from the HSDPA in 3GPPr5. Similarly, the uplink service channel of HSPA+ is E-DCH, so the uplink terminal class can be referred to as the "HSUPA terminal class", which is also different from the "HSUPA terminal class" in 3GPPr6.

The latter is more technologically advanced and faster.

Faster transfer speeds.

HSPA transfer speed is.

The HSPA+ transmission speed is 21m

HSPA should have the speed;

HSPA+ is said to be up to 186m
