Overview of GSM and Its Characteristics
CDMA, GSM900, GSM1800, DCS, PCS, and PHS are all part of the 2G mobile communication technologies. In the United States, GSM operates in the CDMA frequency range of 850-895 MHz and PHS/PCS at 1800-2000 MHz. In Europe, the frequency allocations include CDMA at 850-895 MHz, GSM900 at 920-965 MHz, and GSM1800/DCS at 1800-1920 MHz.
GSM represents the second generation of cellular mobile communication technology, a progression from the analog systems used in the 1980s and preceding the gradual adoption of broadband CDMA technologies.
Despite being considered outdated, GSM remains a fundamental communication technology and continues to play a vital role in the current 5G landscape.
Key Features of GSM Technology:
Time Division Multiple Access (TDMA): GSM utilizes TDMA for its air interface, allowing multiple users to share the same frequency by allocating different time slots. This enhances spectrum efficiency and increases system capacity.
Global Adoption: Since its introduction in the mid-1990s, GSM has been embraced by over 100 countries, making it one of the most prevalent mobile communication standards globally.
Robust Security: The GSM system is designed with strong anti-copying measures, ensuring network security and stability.
Extensive Number Resources: It offers a wide range of mobile number resources to accommodate large user bases.
Clear Call Quality: GSM ensures high call clarity, minimizes dead zones, and enhances the overall user experience.
Low Power Consumption: GSM mobile phones generally consume less power compared to other communication systems, which helps extend battery life.
Open Standards: The system features open interfaces and universal standards, facilitating device compatibility and ease of expansion.
Confidentiality and Security: GSM supports various security protocols, safeguarding user communications and maintaining privacy.
Versatile Services: It caters to diverse user needs by providing a range of services, including voice calls, SMS, and data transmission.
Roaming and Handover: GSM supports seamless roaming and handover capabilities, allowing users to maintain communication continuity while traveling between different regions.
High Transmission Quality: The system delivers reliable transmission quality, ensuring stable communication.
These attributes have contributed to the widespread acceptance and recognition of GSM, establishing it as a foundational technology in mobile communications.
