Why Learn GSM Programming in C/C Today?

As of 2023, GSM communication technology is becoming increasingly obsolete and unsupported. Therefore, learning GSM programming in C/C is a question worth exploring from both a practical and historical perspective.

The Obsolescence of GSM

Understanding the Technological Shift: GSM (Global System for Mobile Communications) is a widely used digital mobile telephone standard. However, in recent years, it has been largely superseded by newer technologies like 3G, 4G, and 5G. In fact, many carriers have already discontinued or are in the process of discontinuing support for GSM technology. This means that learning GSM programming today may serve little to no practical purpose for most developers.

Why GSM is Dying: There are several reasons why GSM is becoming obsolete. One major factor is the rapid development of high-speed data networks such as 3G and 4G, which offer faster internet speeds and better multimedia capabilities. These networks have superior capacity and reliability, making them more attractive for both personal and corporate use. Additionally, the growing importance of Internet of Things (IoT) technology means that newer protocols and standards like NB-IoT, LTE-M, and 5G are being prioritized by most telecom companies.

Practical and Historical Implications

Why Learn GSM Programming Now?: Even though GSM is no longer in widespread use, there still might be valid reasons to learn this technology:

Historical Knowledge: GSM was once the dominant mobile communication standard, and understanding its programming can provide valuable historical insights into the evolution of mobile technologies. This can be beneficial for academic or research purposes. Legacy Systems: Some older equipment and systems may still use GSM technology, especially in emerging markets or in certain industries like agriculture, energy, and security. Learning GSM programming can help in maintaining and troubleshooting these systems. Broader Knowledge Base: Understanding different communication protocols can be useful in developing cross-technology interoperability solutions. It also helps in understanding the challenges and limitations of older technologies, which can inform the design of new systems.

Why It May Not Be Useful: On the other hand, if your primary goal is to develop modern, robust, and scalable mobile applications or IoT solutions, investing time in learning GSM programming might not be the most efficient use of your resources. The skills and knowledge gained from learning newer protocols and technologies will be more relevant and valued in the current job market.

Comparison with 3G, 4G, and 5G

3G, 4G, and 5G: In contrast to GSM, 3G, 4G, and 5G technologies offer significant improvements in terms of speed, reliability, and capability. For instance:

3G: Introduced in the late 1990s and early 2000s, 3G networks provided a significant boost in data speeds and supported mobile internet browsing, video calls, and multimedia messaging services. 4G: Developed in the mid-2000s, 4G networks brought even faster data speeds and wider coverage, enabling high-quality video streaming and real-time communication. 5G: Launched in the mid-2010s, 5G networks have the potential to deliver ultra-high speeds, extremely low latency, and support for massive IoT devices, making it ideal for applications like autonomous vehicles, smart cities, and industrial automation.

Conclusion: While GSM programming still has its place in certain niche applications, learning it today is a practical decision only for those with specific requirements or for the sake of completing a comprehensive knowledge base. For most developers, investing time in learning and mastering more modern and widely supported technologies like 3G, 4G, 5G, or IoT protocols is more beneficial in the current technological landscape.
