What is Hsupa?

The

high -speed Protink Packet Access (HSUPA) works with a 3G mobile phone network and provides a maximum up to 5.76 megabits per second (MBPS). HSUPA is part of a software family with high -speed access to packets (HSPA), maintained and defined by the partnership project 3. Generation (3GPP). The 3GPP Group, consisting of numerous telecommunications associations, is involved in creating specifications for a 3G mobile phone system. Its services allow 3G the current transfer of voice data and non -voted data. To use HSPA logs, you must have a mobile device that is supported by HSPA.

HSUPA improves the performance of an improved reserved channel (e-DCH) by increasing the throughput and reducing delay. In other words, it increases the speed at which your mobile device can communicate with the network. HSUPA is designed to quickly match the parameters of the signal and protocol needed for wireless communication, also known as Link Adaptation. The new protocol also improves the performance of the reductionm Latence. For example, users can be in favor of video recording with better speeds. As for how HSUP is doing its work, it is similar to the high -speed protocol of downlink packets (HSDPA). Basically, HSDPA gives mobile devices to receive large files, including attachments of e-mails and websites.

HSUP also uses several new features. A fast hybrid automatic repetition request (ARQ) is one of them. This allows the basic station in the mobile network to immediately apply for data to transplant data if it contains errors. Increasing more efficient Retransmision requirements can occur faster.

Multiple codes Transfer is also a new feature. It allows you to use up to four codes by one user, rather than using one code per user. With multiple codes available at the same time, the user will see an increase in data speed uplink.

short time inTerval Transmission, which uses the interval of either 2 milliseconds (MS) or 10 MS, is another new feature available by HSUPA. The previous uplink interval ranged from 10 ms to 40 ms. With a shorter interval, the total transmission times are shorter.

Nokia actually created the name HSUPA, but 3GPP uses the term improved uplink (EUL) to link to HSUP.
