High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G and 3G+ . It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity.
Cellular network standards and generation timeline. An Evolved HSDPA network can theoretically support up to 28 Mbit/s and 42 Mbit/s with a single 5 MHz carrier for Rel7 (MIMO with 16QAM) and Rel8 (64-QAM + MIMO), in good channel conditions with low correlation between transmit antennas. Although, real speeds are far lower.
Since the beginning of 2006, Cellcom has been deploying a 3G UMTS-2100 network nationwide, which by the end of 2007 covered than 87% of the population. [citation needed] Cellcom was the first in Israel to launch an HSDPA network (also called "Generation 3.5") nationwide. [citation needed]
In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the US, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.
Moreover, in 2006, SK began revitalizing the 3.5-generation mobile phone market and in the following year, completed the construction of the national HSDPA network. In May 2006, SK Telecom started the world's first commercial 3.5-generation HSDPA service, featuring high-quality video telephony and data transmission, and global roaming access. [16]
