HSDPA INFORMATION
HSDPA :- High Speed Downlink Packet Access.
High Speed Downlink Packet Access (HSDPA) is 3G (Third Generation) Mobile Telephony Communications Protocol in the High Speed Access Access family.
An upgrade for UMTS networks at 1.8 Mbps (Mega bit per second) but upgrades to the network and new user devices led to increased rates of 3.6 Mbps, Followed by 7.2 Mbps and Further down the road, 14.4 Mbps and even 21 Mbps. Also dubbed, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of up to 42 Mbit/s (Mega bit per Second). Further speed increases are available with HSPA+.
HSDPA only handles the downlink while the uplink is handled by a related technology called HSUPA. The combination of both technologies is usually called HSPA.
