What is the difference between HSDPA and Hsupa?

HSDPA (High Speed Downlink Packet Access) is the one that improves the downlink of the data transmission while HSUPA (High Speed Uplink Packet Access) is the one that improves the uplink or transmission from the mobile device to the network.

What are the fundamental differences among HSDPA Hsupa and LTE?

HSPA+ (Evolved High-Speed Packet Access) is not the same as 4G, but it updates the HSPA capability within the 3G UMTS networks. HSPA+ can enable peak download speeds of up to 42 Mbps, whereas the advanced 4G LTE networks (LTE-Advanced Pro) can enable peak download speeds of up to 3 Gbps.

What is the difference between R99 and HSDPA?

The maximum channel rate for HSDPA is 14.4 Mbps, with a peak user data rate of 13.4 Mbps (on MAC level), compared with a maximum user data rate of 384 kbps for R99.

Is Hsupa a 3G?

High-Speed Uplink Packet Access (HSUPA) is a 3G mobile telephony protocol in the HSPA family. This technology was the second major step in the UMTS evolution process. It was specified and standardized in 3GPP Release 6 to improve the uplink data rate to 5.76 Mbit/s, extending the capacity, and reducing latency.

Which modulation scheme is used in HSDPA?

HSDPA 16QAM use As a result the 16QAM modulation format is normally used under high signal conditions, e.g. when the mobile is close to the NodeB and in the clear. The coding rate as well as the modulation are then selected for each 2ms TTI by the NodeB according to its assessment of the conditions.

Is HSPA the same as HSDPA?

HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA). HSDPA allows data rates up to 14.4 Mbit/s in the downlink. HSUPA makes uplink data rates of 5.76 Mbit/s possible.

What is the typical data rate used for HSDPA?

It is also called 3.5G, with transmission rates up to 14.4 Mbps and 20 Mbps (for MIMO systems) over a 5 MHz bandwidth. HSDPA can significantly enhance downlink speeds, with average realistic throughputs of 400–700 kbps and bursts at over 1 Mbps, even in the initial stage.

Is HSDPA a 4G?

HSDPA is sometimes called 3.5G. HSPA+ is an evolution HSPA(HSDPA&HSUPA). It is a 4G technology that allows download at a rate of up to 168Mbps. LTE is a 4G communication standard that supports HD video streaming, download speed as high as 299.6Mbps.
