Hello, everyone!
Today, I would like to share with you an article on GSM in wireless communications.
The (GSM) is an acronym for Global System for Mobile Communication. GSM is a cellular technology that is open and digital and is used for mobile communication. It operates on the 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz frequency ranges. It employs a hybrid of FDMA and TDMA. This post covers all aspects of GSM architecture and how it functions.
In GSM, there are four main cell sizes that are employed :
Macro : Base Station antenna is installed in this size of cell.
Micro : The antenna height in this cell is lower than the usual roof level.
Pico : The diameter of small cells is a few meters.
Umbrella : It fills in the spaces between cells and covers the shadowed areas.
GSM has the following characteristics::
International roaming is supported.
Clarity of voice
Support for a variety of portable devices
Efficiency in terms of spectral and frequency
Handheld gadgets with low power consumption
In the case of network access
ISDN compatibility on a global scale.
GSM is a broader system that is further separated into three subsystems.
BSS : It is the abbreviation for Base Station Subsystem. Between a mobile phone and the network switching subsystem, the BSS manages traffic and signaling. BSS is made up of two parts: BTS and BSC.
NSS : The NSS is an acronym for Network and Switching Subsystem. GSM's fundamental network is the NSS. This functioned as a call and mobility management system for mobile phones in the network. VLR, HLR, and EIR are examples of NSS components.
OSS : Operating Subsystem (OSS) is a term that refers to a set of software components that work together The network operator monitors and controls the system using OSS, which is a functional entity. OMC is a component of OSS.
I will continue to share on this article in the following post.
