What are 3GPP specifications?
The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications. Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings.
How do I read 3GPP specs?
All 3GPP specifications have a specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series, followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series.
What is 3GPP project based on W CDMA?
3GPP was created as the standards organization behind UMTS/wideband CDMA (W-CDMA). UMTS is essentially the 3G upgrade to the 2G GSM networks. UMTS/W-CDMA technologies used a 5 megahertz (MHz) bandwidth carrier. 3GPP2 developed separate standards for 3G technologies, known as CDMA2000.
What is 3GPP protocol?
3GPP, or the 3rd Generation Partnership Project, was initially formed in December 1998 when the European Telecommunications Standards Institute (ETSI) partnered with other standard development organizations (SDOs) from around the world to develop new technologies (or more specifically, technology specifications) for …
What is 3GPP and non 3GPP?
3GPP specifications define how the interworking is achieved between an E-UTRAN (LTE and LTE-Advanced), GERAN (radio access network of GSM/GPRS) and UTRAN (radio access network of UMTS-based technologies WCDMA and HSPA). Non-3GPP means that these accesses were not specified in the 3GPP.
Why is 3GPP important?
While the 3GPP does have 3G in its name, it has developed cellular industry standards since UMTS. The 3GPP is responsible for managing GSM, GPRS, EDGE, HSPA, LTE and LTE-Advanced and Pro. This will require the 3GPP to incorporate more members and understanding of those industries.
What are 3GPP releases?
3GPP uses a system of parallel “Releases” which provide developers with a stable platform for the implementation of features at a given point and then allow for the addition of new functionality in subsequent Releases.
What is WCDMA modulation?
Wideband Code Division Multiple Access (WCDMA) was introduced to provide higher data rates in mobile communication. We have considered two modulation techniques of Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) used in WCDMA systems.
What’s the difference between WCDMA and CDMA?
The main difference between WCDMA and CDMA is that they are designed to work with different networks. WCDMA is a 3G technology designed to work alongside the 3G GSM network. WCDMA uses frequency bands that are 5MHz wide, while CDMA uses bands that are 1.25MHz wide.
Is WIFI a 3GPP?
The current 3GPP specification specifies support for only Wireless LAN (Wi-Fi) Access Network (WLAN) as the non-3GPP access network; hence, the same is considered for the untrusted non-3GPP access network in this paper.
What are the main components of EPC?
The three core elements of the EPC are the Mobility Management Entity (MME), Serving Gateway (SGW), and Packet Data Network Gateway (PGW).
What’s the difference between UMTS and WCDMA in 3G?
In view of its character, it is often referred to as TD-CDMA (Time Division CDMA). There are several key areas of 3G UMTS / WCDMA. Within these there are several key technologies that have been employed to enable UMTS / WCDMA to provide a leap in performance over its 2G predecessors.
What does the maximum output power of a WCDMA mean?
The maximum output power measures the maximum power that the UE can transmit in a bandwidth of at least (1 + 8) times the radio access mode’s chip rate. If the maximum output power is too high, the device may interfere with other channels or other systems. If the maximum output power is too low, this decreases the coverage area.
What are the different types of 3GPP specifications?
To find a particular specification by series, look at the Numbering page. The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications.
How to measure WCDMA RF with the are & scmw500?
Tests Supported in Accordance with 3GPP TS 34.121-1 1CM71_2ERohde & SchwarzWCDMA RF Measurement with CMW500 according to 3GPP TS 34.121 4 1 Introduction Most of the tests specified in Technical Standard 34.121 [1] for 3GPP Rel-99 can be performed with an R&S®CMW500.
