What is UMTS and HSPA?

What is UMTS and HSPA?

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). HSPA also boosts capacity in UMTS networks and provides significant latency reductions.


The answer is ā€œgā€ stand for Generation. The GSM, GPRS and EDGE are 2G (second generation)networks, UMTS/WCDMA/HSPA+/DC-HSPA+ are 3G(third generation) networks, LTE(TD-LTE/FDD) is 4G(Forth generation) network. The basic scheme of UMTS LTE is maintained.

What is UMTS and GSM?

GSM, UMTS and LTE are 2G, 3G and 4G mobile network technologies, respectively. GSM stands for Global System for Mobile Communications, UMTS stands for Universal Mobile Telecommunications System, and LTE stands for Long Term Evolution (of Mobile Networks).

What is GSM vs HSPA?

GSM uses UMTS standard and HSPA (for 3.5G, which is even faster), while CDMA uses EV-DO data service. The main disadvantage of EV-DO is that it is limited to data or voice calls only, never both.

Is HSPA the same as UMTS?

Simply put, HSPA is faster than UMTS. UMTS is the umbrella name for 3G technologies as defined by 3GPP. HSPA was an important evolution of 3G with additional downlink (HSDPA) and uplink speed (HSUPA).

Where is UMTS used?

The 2100 MHz band (downlink around 2100 MHz and uplink around 1900 MHz) allocated for UMTS in Europe and most of Asia is already used in North America. The 1900 MHz range is used for 2G (PCS) services, and 2100 MHz range is used for satellite communications.

Is HSPA+ faster than 4G?

HSPA+ or Evolved High Speed Packet Access, in fact, has speeds comparable to the newer LTE networks. According to AndroidAuthority, downlink speeds are comparable between the two. This is one of the main factors behind the delayed launch of complete 4G LTE networks.ā€

What is R99 traffic in UMTS?

Besides, the UMTS system still accom- modates a significant amount of Release 99 (R99) traffic such as voice telephony. In R99, user traffic is transported via Dedicated Channels (DCHs) over the radio interface. HSPA traffic is characterized by high peak data rates and high burstiness.

What is UMTS in wireless network?

The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.

Which is faster HSPA or UMTS?

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. Even higher speeds of up to 337.5 Mbit/s are possible under 3GPP Release 11. The first phase of HSDPA was specified in the 3GPP release 5.

What is TD Scdma CDMA UMTS?

TD-SCDMA is a time division duplex, TDD version of UMTS that was developed in China and offered some key advantages as a TDD version. TD-SCDMA standards for Time Division – Synchronous CDMA. Much of the work to develop TD-SCDMA was undertaken by China Academy of Telecommunications Technology (CATT).


Mobile Communication: What are GSM, GPRS, EDGE, UMTS, HSPA and LTE? In mobile communications, frequently, the terms GSM, GPRS, EDGE, UMTS, HSPA and LTE appear. These terms refer to different standards of data transfer and are noticeable for the mobile phone user mainly in a different data transfer rate.

Is there any link between UMTS/HSPA+ and LTE?

However, there is no link between UMTS/HSPA+ and LTE. We have a detailed post on HSPA+ vs LTE if you are interested. GSM and CDMA can be seen as two technology tracks that still exist for 2G and 3G cellular technologies. 2G GSM and 3G UMTS form the first track, whereas 2G IS-95 and 3G CDMA2000 form the second track.

What is UMTS (universal mobile telecommunications system)?

UMTS is a mobile system with speeds of max. 384 kbit / s UMTS is the successor of GSM and commercially available since 2004 in Germany. The Universal Mobile Telecommunications System (UMTS) is a wireless standard of the third generation (3G), with significantly higher data rates (up to 21 Mbit / s HSPA +, otherwise max.

What is the difference between GSM UMTS and LTE?

GSM stands for Global System for Mobile Communications, UMTS stands for Universal Mobile Telecommunications System, and LTE stands for Long Term Evolution (of Mobile Networks). GSM uses TDMA and FDMA for its air interface, UMTS uses WCDMA, and LTE uses a combination of OFDMA and SC-FDMA.
