What is the difference between UMTS and HSPA?
Technology Overview 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.
What is UMTS HSPA HSPA+?
A Third Generation Mobile Cellular System HSPA+ or Evolved High-Speed Packet Access, is a technical standard for wireless, broadband telecommunication. HSPA+ enhances the widely used WCDMA (UMTS) based 3G networks with higher speeds for the end user that are comparable to the newer LTE networks.
Is LTE faster than HSPA+?
The theoretical maximum download speed of HSPA+ is actually higher than LTE at 168mbps compared to 100mbps. Theoretical upload speed is weighted firmly in LTE’s favour though with 50mbps playing 22mbps.
How does UMTS differ from 2G networks?
UMTS stands for Universal Mobile Telecommunications System, developed based on 3GPP standards. Its network composed of three main parts UE (User Equipment), Radio Access Network (RAN) and Core Network….Difference between UMTS and GSM :
| S.No. | UMTS | GSM |
|---|---|---|
| 1. | UMTS is already 3G. | GSM is 2G and 2.5G. |
| 2. | It is mainly CDMA-based. | It is typically based on TDMA . |
Is UMTS same as 3G?
UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps).
Is HSPA GSM or CDMA?
Meaning, these technologies make accessing the internet through your phone possible. 3G CDMA networks utilize EVDO, while 3G GSM networks use HSPA and HSPA+. The differences between EVDO and HSPA are how they work and the speeds they can achieve.
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). That evolution took the original 3G maximum bandwidth from 384 kbit/s in downlink and uplink to 14.4 Mbit/s and 5.8 Mbit/s respectively.
What is the difference between HSDPA and HSUPA?
Both HSDPA and HSUPA falls under HSPA. HSPA+ supports speeds of 84Mbps in the downlink and about 23Mbps in the uplink. HSPA+ follows 3GPP R7,R8 and R9 standards.
What is the difference between HSDPA modem and HSPA modem?
The devices which support these technologies are called HSDPA modem and HSUPA modem. Both HSDPA and HSUPA falls under HSPA. HSPA+ supports speeds of 84Mbps in the downlink and about 23Mbps in the uplink. HSPA+ follows 3GPP R7,R8 and R9 standards.
What is the transfer rate of HSDPA?
Most HSDPA technology shows a theoretical transfer rate of 1.8, 3.6, 7.2, and 14.0 Mbit/s. However, there are further speed increases with the availability of the HSPA+ (providing speeds of up to 42 Mbit/s on the downlink, and 84 Mbit/s with the Release 9). 1.
