What is a GSM link?
GSM (Global System for Mobile communication) is a digital mobile network that is widely used by mobile phone users in Europe and other parts of the world. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.
What mechanism does GSM use?
Time Division Multiple Access
GSM makes use of narrowband Time Division Multiple Access (TDMA) technique for transmitting signals. 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.
How is a BTS able to communicate with several subscribers at the same time?
Typically a BTS will have several transceivers (TRXs) which allow it to serve several different frequencies and different sectors of the cell (in the case of sectorised base stations). A BTS is controlled by a parent base station controller via the base station control function (BCF).
What does BSC stand for in telecom?
A base station controller (BSC) is a network element that controls and monitors a number of base stations and provides the interface between the cell sites and the mobile switching center (MSC).
Who controls a group of BTS or cell towers?
The base transceiver station (BTS) is connected via landline to a radio network controller (RNC). The RNC manages several base transceiver stations. The radio network controller is connected to a Mobile Switching Center. Each Mobile Switching Center (MSC) manages the cell towers in a single coverage area.
Is GSM or CDMA better?
First, neither GSM or CDMA is technically better; they ultimately provide the same service and the quality of a network depends on the carrier, not the cellular standard used. Second, GSM phones can be unlocked and switch carriers, whereas CDMA phones are locked to a carrier.
Is GSM the same as 4G?
LTE (Long Term Evolution) is a 4G communication standard designed to be 10x faster than standard 3G. GSM is a digital cellular technology used to transmit data and voice communication at a frequency range of 850MHz to 1900MHz. GSM technology uses a Time Division Multiple Access (TDMA) technique to transmit data.
What are the components of GSM technology?
GSM Technology Architecture 1 Network Switching Subsystem (NSS) In GSM system architecture, it includes different elements, which are frequently known as the core system/network. 2 Base Station Subsystem (BSS) It acts as an interface between the mobile station and the network subsystem. 3 Mobile Station.
What is GSM (Global System for mobile communication)?
What is GSM (Global System for Mobile communication)? GSM (Global System for Mobile communication) is a digital mobile network that is widely used by mobile phone users in Europe and other parts of the world.
What are the different GSM frequency bands?
For instance, in the 900-MHz E-GSM band, the block 880-915 MHz is used for transmission from mobiles to network, and the block 925-960 MHz is used for the transmission from network to mobiles. Table 1.1 gives a summary of uplink and downlink frequency bands for the different GSM systems.
What happened to the GSM network?
That same year, the GSM standard frequency band was expanded from 900 MHz to 1,800 MHz. In 2010, GSM represented 80% of the global mobile market. However, several telecommunications carriers have decommissioned their GSM networks, including Telstra in Australia. In 2017, Singapore retired its 2G GSM network.
