Mobile network technology is constantly being improved, primarily to let you send and receive data faster.
HSPA (High Speed Packet Access) is a mobile telephony technology that allows for data transmission speeds up to 21 Mbps. HSPA+ (also called Evolved HSPA or 4G) is a further evolution of HSPA that offers data speeds of up to 42 Mbps.
HSPA+ provides High Speed Packet Access data rates up to 84 Megabits per second (Mbit/s) on the downlink and 22 Mbit/s on the uplink through the use of a multiple-antenna technique known as MIMO (for “multiple-input and multiple-output”) and higher order modulation (64QAM).
HSPA+ also introduces an optional all-IP architecture for the network where base stations are directly connected to IP based backhaul and then to the ISP's edge routers. The technology also delivers significant battery life improvements and dramatically quicker wake-from-idle time - delivering a true always-on connection. HSPA+ should not be confused with LTE, which uses a new air interface.
As of November 2009, there are 20 HSPA+ networks running in the world at 21 Mbit/s and two are running at 28 Mbit/s.[3] The first to launch was Telstra in Australia in late 2008, with access in February 2009 to speeds up to 21 Mbit/s.
