HSDPA menan High Speed Downlink Packet Access. High Speed Downlink Packet Access, or HSDPA, is a packet based data service feature of the in WCDMA standard which provides a downlink with data transmission up to 8-10 Mbps (and 20 Mbps for MIMO systems) over a 5MHz bandwidth in WCDMA downlink. The high speeds of HSDPA is achieved through techniques including; 16 Quadrature Amplitude Modulation, variable error coding, and incremental redundancy. HSDPA is a technology upgrade to current UMTS networks.

Having HSDPA means you don't have to be tethered to an office cubicle or stuck in a hotspot to get broadband Internet speeds.

[[High-Speed Packet Accesor HSDPA, a new transport layer channel, High-Speed Downlink Shared Channel (HS-DSCH), has been added to UMTS release 5 and further specification. It is implemented by introducing three new physical layer channels: HS-SCCH, HS-DPCCH and HS-PDSCH. The High Speed-Shared Control Channel (HS-SCCH) informs the user that data will be sent on the HS-DSCH, 2 slots ahead. The Uplink High Speed-Dedicated Physical Control Channel (HS-DPCCH) carries acknowledgment information and current channel quality indicator (CQI) of the user. This value is then used by the base station to calculate how much data to send to the user devices on the next transmission. The High Speed-Physical Downlink Shared Channel (HS-PDSCH) is the channel mapped to the above HS-DSCH transport channel that carries actual user data.

High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity.

HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. It is an evolution and improvement on W-CDMA, or Wideband Code Division Multiple Access, a 3G protocol. HSDPA improves the data transfer rate by a factor of at least five over W-CDMA. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps (megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA. HSDPA improves on W-CDMA by using different techniques for modulation and coding. It creates a new channel within W-CDMA called HS-DSCH, or high-speed downlink shared channel. That channel performs differently than other channels and allows for faster downlink speeds. It is important to note that the channel is only used for downlink. That means that data is sent from the source to the phone. It isn't possible to send data from the phone to a source using HSDPA. The channel is shared between all users which lets the radio signals to be used most effectively for the fastest downloads. The widespread availability of HSDPA may take a while to be realized, or it may never be achieved. Most countries did not have a widespread 3G network in place as of the end of 2005. Many mobile telecommunications providers are working quickly to deploy 3G networks which can be upgraded to 3.5G when the market demand exists. Other providers tested HSDPA through 2005 and are rolling out the service in mid to late 2006. Early deployments of the service will be at speeds much lower than the theoretically possible rates. Early service will be at 1.8 Mbps, with upgrades to 3.6Mbps as devices are made available that can handle that increased speed. The long-term acceptance and success of HSDPA is unclear, because it is not the only alternative for high speed data transmission. Standards like CDMA2000 1xEV-DO and WiMax are other potential high speed standards. Since HSDPA is an extension of W-CDMA, it is unlikely to succeed in locations where W-CDMA has not been deployed. Therefore, the eventual success of HSDPA as a 3.5G standard will first depend upon the success of W-CDMA as a 3G standard.

HSDPA is a connection mode for surfing the internet, receiving email and so on. 7.2 Mbps is the speed of the connection, meaning you can download at 7.2 megabyte per second. HSDPA is the fastest mobile internet connection to date, of course not as fast as wi-fi,

AT&T says its HSDPA network can hit speeds of 3.6 Mbps to 14.4 Mbps. Real-world speeds typically are slower than that, but HSDPA is still a super-fast network.

The full form of HSDPA is High-Speed Downlink Protocol Access. This is a technology that is generally incorporated in the latest high tech mobile phones for the purpose of making the data transfer a faster process. This is designed for the 3G networking technologies. HSDPA is directly related to the GSM and UMTS services. They are capable of supporting the speed up to the 14.4 MBPS for data transfer and it starts from 1.8 MBPS. You might feel pretty confused to hear that this is a high speed technology as there are many other methods available with speed that is far better than this. But when it comes to the mobile phone technology this is one of the best data transferring speed available. Some people only adore the downlinking speed of HSDPA wherein the expandable transferring capacity equally good with this particular mechanism. You are free to avail a lot of facilities in your cellular phone with the help of HSDPA. This includes 30 GB transferred data monthly, mobile television availability for up to 300 minutes, apart from talk time of approximately 1000. The HSDPA technology has gained huge popularity in the world. They are used in almost 54 countries all over the world and there are around hundred networks that support this method. The downlinking speed offered by these networks is almost 3.6GBPS. But the networks are stilling working on the speed part and trying to upgrade it to 7.2 MBPS. Right now there is only one network that is offering the best speed which is 14. 4 MBPS. Hopefully the others will surely improve their facility to outperform this contender. Now that you aware of this unique HSDPA technology the only thing that you need to avail this facility is a mobile phone which is compatible to this. The number of such devices available in the market is around 170. They include the latest phones from various renowned mobile companies like Nokia, Motorola and Sony Ericsson. Apart from the mobile phones you can avail this technology through the laptops & notebook pcs. Companies like Lenovo, Dell, Acer, Panasonic, and Fujitsu have incorporated HSDPA in their products as the key feature that intensifies the data transfer process. There are some others technologies as well which are coming up to outperform HSDPA in the data transferring speed among which the strongest contender is EVDO which is meant for the CDMA technology.
