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.
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.
The network is built on the W-CDMA technology under the UMTS standard and operates at the frequency of 2100 MHz [6] (two FDD bands: 1935—1950 MHz and 2125—2140 MHz [7]).It also supports the HSDPA protocol, which theoretically allows achieving a download speed of 14.4 Mbps.

Project Genesis was completed by the end of 2004. Later, this network was upgraded to EDGE across the GSM footprint. In 2005, AT&T launched a broadband network known as "BroadbandConnect", based on UMTS and HSDPA, to counter Verizon Wireless and Sprint's EV-DO networks. UMTS service was launched on December 6, 2005, in Seattle, Portland, San ...
Its prepaid services are exclusively sold through Newtel LLC. Mobicom introduced 3.5G networking in 2009, and provides HSPA. Mobicom network support phones with UMTS 2100, HSDPA 2100, HSUPA 2100 or HSPA 2100 bands.
The following is a list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. This list does not aim to cover all networks, but instead focuses on networks deployed on frequencies other than 2100 MHz which is commonly deployed around the globe and on Multiband deployments.
