Telecom recollections

 


After 31 years of work in software ,mainly in Telecom and related software and witnessing massive telecom transformations with world's largest telecom companies and billions of dollars spending , many still struggling with micro services and cloud adoption, I foresee a radical shift in the next 5-10 years. The transition from 5G to 6G, alongside AI and quantum computing, will create intelligent, self-optimizing networks enabling holographic communication, digital twins, and immersive experiences. AI-driven network management, quantum-enhanced security, edge computing dominance, and a near-complete shift to cloud-native architectures will redefine industries and daily life, marking an era of unprecedented connectivity and technological convergence.

The leap from 5G to 6G, coupled with the potential of quantum computing, promises a paradigm shift. 6G, operating in the terahertz spectrum, will deliver speeds and latencies previously unimaginable, enabling holographic communication, digital twins, and AI-driven spatial computing. This will necessitate a fundamental redesign of network architectures, moving towards intelligent, self-optimizing systems.

Looking ahead 5-10 years, the world will be radically different:

AI-Driven Networks: AI will be deeply embedded in network operations, from predictive maintenance and dynamic resource allocation to autonomous network slicing and security. This will lead to unprecedented levels of efficiency and responsiveness.

Quantum-Enhanced Security and Optimization: Quantum computing will revolutionize network security with unbreakable encryption, while also enabling optimization of complex network configurations.

Edge Computing Dominance: Edge computing will become the norm, enabling low-latency applications and real-time data processing for IoT, autonomous vehicles, and immersive experiences.

Convergence of Physical and Digital Worlds: Digital twins and holographic communication will blur the lines between physical and digital realities, transforming industries like manufacturing, healthcare, and entertainment.  

Personalized and Immersive Experiences: 6G will enable highly personalized and immersive experiences, with holographic communication and advanced virtual/augmented reality becoming commonplace.  

Continued transition to cloud native: The move to cloud native architectures will be mostly complete, allowing for extreme levels of agility, and speed of deployment.

Open RAN adoption: Open RAN will be widely adopted, allowing for more vendor diversity and innovation.
