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.

An especially notable development during this time is the smartphone (for example, the iPhone, and the Android family), combining the abilities of a PDA with a mobile phone, leading to widespread demand for mobile internet connectivity. 3G has also introduced the term "mobile broadband" because its speed and capability made it a viable ...
This means it can handle four times as much traffic as standard GPRS. EDGE meets the International Telecommunication Union's requirement for a 3G network, and has been accepted by the ITU as part of the IMT-2000 family of 3G standards. [4] It also enhances the circuit data mode called HSCSD, increasing the data rate of this service.

Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. [1]
