The GSM standard describes the functions and architecture of cellular phones. The GSM standard integrates four separate elements: the mobile device, the base station subsystem, the network switching system, and the operation and support subsystem. The mobile device connects to the network with a SIM card. The SIM contains relevant information identifying the subscriber. The base station system contains the mobile transceiver station (BTS) and a network controller, called the Mobile Switching Center (MSSC). The network core consists of the Home Location Register, or HLR, which tracks a subscriber’s position and other information.
The GSM standard is a global network of cellular devices, spanning the globe. It is the basis for all mobile devices in the world. The network can communicate with any other GSM-enabled device. It also enables voice calls, data and video, and a variety of other functions. However, GSM is the only standard that supports voice calling, as all other mobile phone systems have a different standard.
The GSM security model has two subsystems: the appliance control subsystem allows users to remotely control household appliances while the security alert subsystem provides fully automated security monitoring. These two subsystems allow users to change the condition of household appliances and receive security alerts via SMS. The GSM security model provides confidentiality, but offers limited authorization and non-repudiation. However, some users may not want this feature. In such a case, the user will have to download the GSM software to make the change.
The GSM standard was developed by the European Telecommunications Standards Institute (ETSI). The global system for mobile communication (GSM) is a digital cellular communication standard. GSM represents 70% of world digital cellular services and is widely implemented. It allows for the mobile devices to communicate with base stations, switching systems, and other devices. If you’d like to know more about the GSM standard, you can view a history of the GSM network and its rollout.
The GSM uses a few different cryptographic algorithms to ensure security. The first algorithm, A5/1, was developed. The second, A5/2, has serious vulnerabilities. The Hacker’s Choice group has started a cracking project based on FPGAs. The GSM uses several different cryptographic algorithms, each with different strengths. Choosing the right one depends on the needs of your project. It is important to know how many GSM algorithms will be supported.
In the cellular IoT world, GSM has become the most common connectivity choice. However, with cellular carriers beginning to sunset 2G networks in 2016, manufacturers of modern IoT devices must evaluate the viability of using this technology in their region. Moreover, the radio frequency spectrum is finite and 2G networks are using part of it that could be better utilized by other technologies. You can read more about the GSM standard below
The GSM specification covers an area between 824 and 894 MHz and between 1850 and 1990 MHz. In other words, GSM cellular systems use unique codes and numbers to send and receive data. Each SIM card is assigned an IMSI (International Mobile Subscriber Identity) that is unique to that particular user. In addition to this, some phone networks create a short-term code called a Temporary Mobile Subscriber Identity.
