What is DC HSPA?

DC-HSPA is a “dual carrier” or “dual channel” form of HSPA+ that achieves greater upload and download speeds by using two 5MHz bands of spectrum in parallel instead of relying on the normal single 5MHz band of spectrum used by HSPA+ and other HSPA network technologies.

What is UMTS HSPA +/ DC HSDPA?

UMTS provides a clear evolutionary path to high-speed packet access (HSPA). 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.

Which came first CDMA or GSM?

While GSM is in fact older from a commercial standpoint – CDMA technology is actually older overall, and was first developed at the beginning of World War II.

Why does my phone say E instead of 4G?

E stands for Edge, aka 2G data service. You could say E = slow. There’s few areas left in the country (maybe none by now) where T-Mobile offers only 2G service. Probably everywhere there’s a T-Mobile signal at least 3G service is available.

What is the definition of Dual Cell HSUPA?

Dual-Carrier HSUPA, also known as Dual-Cell HSUPA, is a wireless broadband standard based on HSPA that is defined in 3GPP UMTS release 9. Dual Cell (DC-)HSUPA is the natural evolution of HSPA by means of carrier aggregation in the uplink.

What is the concept of DC HSPA / DC-HSDPA?

The concept behind DC-HSPA / DC-HSDPA is to provide the maximum efficiency and performance for data transfers that are bursty in nature – utilising high levels of capacity for a short time.

Why are there so many categories in HSUPA?

In the same way that HSDPA has a series of categories defined, so too does HSUPA. The HSUPA categories define the basic capabilities for the handset or UE and enable the base station or Node B to communicate effectively, knowing the limits of the performance.

Is the dual carrier DC-HSDPA a 3GPP feature?

The Dual Carrier DC-HSDPA is a 3GPP Release-8 feature and is already a reality in numerous commercial deployments in the world. The DC-HSDPA is limited to 2 adjacent carriers of 5 MHz. In Release-9 the adjacent carrier limitation is overcome, to provide a Dual Band HSDPA operation with separate frequency bands with MIMO.
