What is the architecture of GSM?
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 elements of BSS in GSM architecture?
Base Station Subsystem (BSS) It consists of two elements: Base Transceiver Station (BTS): The BTS used in a GSM network comprises the radio transmitter receivers, and their associated antennas that transmit and receive to directly communicate with the mobiles. The BTS is the defining element for each cell.
What are the main parts of GSM architecture?
GSM – Architecture
- The Mobile Station (MS)
- The Base Station Subsystem (BSS)
- The Network Switching Subsystem (NSS)
- The Operation Support Subsystem (OSS)
What are the components of BTS?
A typical BTS comprises of a Transceiver (TRX) which handles transmission and reception of signals; sending and reception of signals to or from higher network entities, a Combiner which Combines feeds from several TRXs so that they could be sent out through a single antenna thus reducing the number of antennas that …
How does GPRS architecture differ from GSM architecture?
The GSM is a circuit-switched type of network. The GPRS is a packet-switched type of network. The GSM technology provides a data rate of about 9.6 kbps (kilobytes per second) for all of its users. The GPRS technology provides a data rate of about 14.4 kbps to 115.2 (kilobytes per second) for all of its users.
What network is GSM?
AT and T-Mobile are GSM wireless networks. Code-division multiple access (CDMA) is used mainly in the US. Verizon uses CDMA technology and is the largest wireless carrier in the US, but CDMA market share around the world is estimated to be less than 20%.
What are the three subsystems of GSM?
The three subsystems (the user subsystem, the Network Switching Subsystem, NSS, and the Base Station Subsystem BSS, including the network components according to the GSM standard, are shown.
What is the function of BTS?
The BTS connects mobile devices to the network. It sends and receives radio signals to mobile devices and converts them to digital signals that it passes on the network to route to other terminals in the network or to the Internet.
What are the operations of BTS?
The BTS is a telecoms infrastructure used to facilitate wireless communication between subscriber device and telecoms operator network. The subscriber device can be mobile phone, wireless internet devices while the operator network could be a GSM, CDMA or TDMA platform.
What is the difference between GPS and GSM and GPRS?
Key Differences Between GPS and GPRS GPS specifies the object location in terms of latitude and longitude. On the contrary, GPRS is the enhanced version of GSM which provides high data rates for the cellular systems. GPS uses a constellation of 24 satellites that orbit the earth to locate the position.
What is the advantage of GPRS over GSM architecture?
An advantage of GPRS over GSM is that GPRS has a much higher data transmission speed. GPRS can be used as the bearer of SMS. If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved. This is much faster than SMS over GSM.
What is the purpose of GSM?
GSM was developed using digital technology. It has an ability to carry 64 kbps to 120 Mbps of data rates. Presently GSM supports more than one billion mobile subscribers in more than 210 countries throughout the world. GSM provides basic to advanced voice and data services including roaming service.
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.
How many subsystems are there in GSM architecture?
three subsystems
A GSM network is split into three subsystems which are described in more detail below: The Base Station Subsystem (BSS), which is also called ‘radio network’, contains all nodes and functionalities that are necessary to wirelessly connect mobile subscribers over the radio interface to the network.
What is the GSM architecture?
The GSM architecture network interfaces between elements are also mentioned. MS, BSS and NSS stand for Mobile Station, Base Station Subsystem and Network and Switching Subsystem respectively. GSM is the short form of Global System for Mobile Communications. It is called 2G or Second Generation technology.
What is virtual private network?
Virtual Private Network (VPN) | An Introduction. VPN stands for virtual private network. A virtual private network (VPN) is a technology that creates a safe and encrypted connection over a less secure network, such as the internet. Virtual Private network is a way to extend a private network using a public network such as internet.
What are GSM network interfaces?
Refer Gsm Network Interfaces >> . The NSS is core of the GSM architecture. It performs major functions of the system such as mobility management, subscriber data management, cell handling, switching, authentication, equipment validation etc. Due to its core functionalities, it is also referred as CN (Core Network).
What are the functional units of GSM network?
A GSM network comprises of many functional units. These functions and interfaces are explained in this chapter. 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.
