What is 3G cellular network architecture?
The 3G network architecture The Core Network (CN) is the part of the UMTS network that provides services to final users; it can be connected to different types of networks supporting different communication protocols. The CN is composed by the Circuit Switched CN (CS CN) and a Packet Switched CN (PS CN).
What is GSM GSM architecture?
GSM is an open and digital cellular technology used for mobile communication. It uses 4 different frequency bands of 850 MHz, 900 MHz, 1800 MHz and 1900 MHz . It uses the combination of FDMA and TDMA. This article includes all the concepts of GSM architecture and how it works.
What are the characteristics of 3G network?
Some of the main features of 3G are:
- Speed of up to 2 Mbps.
- Increased bandwidth and data transfer rates.
- Send/receive large email messages.
- Large capacities and broadband capabilities.
What traffic routing technology is used in 3G core network?
The 3G core network use a hierarchical structure for both routing traffic toward internal servers (e.g., for visual voice-mail) and channeling traffic to reach external networks (including the Internet).
What are the three main systems the GSM network depends on?
The GSM network is divided into three major systems: the switching system (SS), the base station system (BSS), and the operation and support system (OSS). The basic GSM network elements are shown in Figure 2.
What is 3G network and how does it work?
3G is the third generation of wireless mobile telecommunications technology. It is the upgrade over 2G, 2.5G, GPRS and 2.75G EDGE networks, offering faster data transfer, and better voice quality. This network was superseded by 4G, and later on by 5G.
What are the advantages of 3G network?
3G networks offer users advantages such as:
- New radio spectrum to relieve overcrowding in existing systems.
- More bandwidth, security, and reliability.
- Interoperability between service providers.
- Fixed and variable data rates.
- Asymmetric data rates.
- Backward compatibility of devices with existing networks.
Which protocol supports 3G in CDMA?
Explanation: 3GPP is a 3G Partnership Project for Wideband CDMA standards based on backward compatibility with GSM and IS-136.
Which modulation technique is used by GSM?
Gaussian Minimum Shift Keying (GMSK)
The technology behind the Global System for Mobile communication (GSMTM) uses Gaussian Minimum Shift Keying (GMSK) modulation a variant of Phase Shift Keying (PSK) with Time Division Multiple Access (TDMA) signalling over Frequency Division Duplex (FDD) carriers.
What are the components of a GSM network?
The GSM network has four separate parts that work together to function as a whole: the mobile device itself, the base station subsystem (BSS), the network switching subsystem (NSS) and the operation and support subsystem (OSS).
How does GSM module work?
A customised Global System for Mobile communication (GSM) module is designed for wireless radiation monitoring through Short Messaging Service (SMS). This module is able to receive serial data from radiation monitoring devices such as survey meter or area monitor and transmit the data as text SMS to a host server.
What are the differences between 3G network architecture and 2G network architecture?
The primary difference between 2G and 3G networks for mobile subscribers is that they get to enjoy faster Internet browsing and data downloading on 3G. On average, the speed of data transmission on a 2G network is only 170Kbps, while in 3G networks the downloading speed can go up to 42Mbps (or 43,000 Kbps).
What is GSM and UMTS?
UMTS is the 3G standard for the GSM network. UMTS uses Wideband Code Division Multiple Access (W-CDMA) to increased voice capacity and provide faster speeds. The 3G GSM network does not use FDMA or TDMA technology to transmit information like 2G GSM; it uses CDMA technology.
What is the 3G system?
The 3G system consists of two main parts: the User Equipment (UE) and the UMTS Terrestrial Radio Access Network (UTRAN). The UE is the mobile phone and the UTRAN is the base station and the network intelligence. Both the UE and the UTRAN are composed of different layers.
What is the protocol stack of 3G?
Figure 3: Protocol stack för the user plane. Description of 3G architecture: User Equipment. The 3G system consists of two main parts: the User Equipment (UE) and the UMTS Terrestrial Radio Access Network (UTRAN). The UE is the mobile phone and the UTRAN is the base station and the network intelligence.
Does the GSM standard include the 3G CDMA technology?
The GSM standard does not include the 3G Universal Mobile Telecommunications System (UMTS) code division multiple access (CDMA) technology nor the 4G LTE orthogonal frequency-division multiple access (OFDMA) technology standards issued by the 3GPP.
What are the components of GSM network?
The GSM network can be broadly divided into − The MS consists of the physical equipment, such as the radio transceiver, display and digital signal processors, and the SIM card. It provides the air interface to the user in GSM networks. As such, other services are also provided, which include −
