GSM is a standard for digital cellular communications, which means that it provides a platform for mobile devices to communicate with each other wirelessly. The GSM module is a specialized device that enables a device to send and receive data over the GSM network. The GSM network is an essential component of modern communication systems. It is ...
The Global System for Mobile Communications (GSM) is a family of standards to describe the protocols for second-generation digital cellular networks, [2] as used by mobile devices such as mobile phones and mobile broadband modems. GSM is also a trade mark owned by the GSM Association. [3] "GSM" may also refer to the voice codec initially used ...
