LTE Communication
LTE (Long-Term Evolution) and GSM (Global System for Mobile Communications) are two major cellular technologies that facilitate mobile communication.
LTE is a standard for wireless broadband communication and represents a significant advancement over previous cellular technologies. It provides high-speed data transfer rates and supports a wide range of mobile applications.
GSM is a widely adopted standard for 2G cellular networks, known for its reliable voice communication and text messaging capabilities. It laid the foundation for subsequent mobile communication technologies.
