With the sunsetting of 2G and 3G technologies, and the ascent of 5G and 6G on the horizon, Richard Lemmers, Chief Commercial Officer at Openmind Networks, outlines the significance for telecom operators in embracing this future and planning for a seamless transition.

The telecommunications industry has always been a pioneer in technological advancements, propelling the digital revolution and ensuring seamless connectivity. As we stand on the precipice of a new era, it’s important for telecom operators to remain at the forefront.

The Sunsetting of 2G and 3G

2G and 3G networks have been instrumental in shaping the modern world, but with evolving technology and user demands, their limitations are now apparent. Telecom operators face a pivotal decision on when and how to retire these legacy networks. While 2G and 3G have served the industry well, their diminishing relevance and the escalating cost of maintenance provide a compelling argument for their sunsetting.

Benefits of Sunsetting

1. Spectrum Efficiency

Retiring 2G and 3G networks allows operators to repurpose valuable spectrum bands, unlocking the full potential of 5G and 6G technologies.

2. Cost Savings

Maintaining aging infrastructure entails substantial costs for telecom operators. By sunsetting legacy networks, operators can channel resources into building and enhancing next-generation networks.

3. Enhanced User Experience

5G and 6G promise unparalleled speed, reduced latency, and increased capacity, providing users with an exceptional and immersive experience.

Preparing for 5G and 6G Uptake

The advent of 5G and the promising future of 6G bring tremendous opportunities for telecom operators to redefine their services and thrive in the digital age. Here are the crucial steps to prepare for the adoption of 5G and 6G.

1. Infrastructure Investment

Building a robust infrastructure is the cornerstone of successfully implementing 5G, and eventually, 6G. Operators must invest in upgrading existing infrastructure, including cell towers, small cells, and backhaul networks.

2. Spectrum Acquisition

Securing sufficient spectrum is pivotal for realizing the full potential of 5G and 6G. Telecom operators must actively participate in spectrum auctions and ensure a strategic mix of low, mid, and high-frequency bands.

3. Collaboration and Partnerships

Telcos should embrace partnerships with equipment manufacturers, application developers, and other industry players. Application developers can thrive in the 5G era, creating unthought-of new experiences for end users without telcos needing to generate the experiences. Equally for equipment manufacturers, telecom companies can benefit from their huge R&D resources to bring superb new tech to life. See for example the new Apple Vision Pro VR headset, which will change the game in a world where 5G is the standard.

4. Network Slicing and Edge Computing

Operators can now utilize network slicing and edge computing to provide tailored services for different industries and use cases. This will enable operators to offer low-latency, high-performance services, such as autonomous vehicles and augmented reality on different slices of their networks.

Some slices might be enhanced mobile broadband, some might be ultra reliable low latency communications and some might be massive machine-type communications. Such capabilities position telcos to compete with private networks.

5. Invest in Cybersecurity

As networks become more complex, the importance of robust cybersecurity measures cannot be overstated. Ensure that your network is equipped with the latest security protocols to safeguard against potential threats. Employing AI to analyze network traffic in real-time and identify or quarantine suspicious activity is crucial.

Benefits of 5G and 6G Uptake

1. Connectivity for IoT and Smart Devices

5G and 6G will unlock the full potential of IoT by offering seamless connectivity for smart devices, enabling smart cities, homes, and industries. It is worth noting that while 2G plays a temporary role in connecting IoT devices, it will eventually be replaced by 5G.

2. Industry 4.0

These advanced networks will revolutionize industries through automation, real-time data analysis, and remote operations, paving the way for Industry 4.0 and beyond. Private 5G networks are already providing greatly enhanced capabilities for the likes of smart cities (as is the case in Las Vegas), and for mega factories like Volkswagen in Germany with huge machine-to-machine communication and advanced robotics.

3. Innovation and Services

5G and 6G will usher in a new wave of innovative services and applications, from augmented and virtual reality experiences to telemedicine and beyond. For network operators, there are likely to be advances in network slicing as outlined above. 5G opens up the possibility of app developers offering new services on the network to augment the offerings of the networks themselves. In this sense, it is important to see the latest generations of networks as being hosting areas for innovation, rather than just being innovative themselves.

Network Convergence and the Importance of SMS Protocol

1. Moving to 5G

The transition to 5G will push telecom operators to integrate multiple technologies and services into a single, unified network infrastructure. This network consolidation is pivotal for a seamless transition, an improved quality of service and optimal resource utilization.

2. IoT and Legacy SMS Protocol

While the movement to IoT is gaining momentum, it’s important to note that it still relies on legacy SMS protocol for linking and waking-up devices. As we embrace 5G and 6G, exploring more efficient and modern communication protocols for IoT could further enhance its capabilities.

3. SMS vs RCS

SMS remains the king of messaging. SMS is the sole messaging protocol supported by all generations, from 2G to 5G, giving it unparalleled reach compared to other messaging solutions.

By contrast, RCS – long considered to be the natural successor of SMS – has not achieved the same widespread adoption yet. The rollout of 5G and improved network connectivity may, in time, increase the adoption of RCS, so it’s crucial that operators have a strategy for improving their messaging infrastructure in future.


Telecom operators are at a crossroads, bidding farewell to legacy 2G and 3G networks while wholeheartedly embracing the opportunities presented by 5G and 6G. Adequate preparation and strategic planning enable operators to leverage these advancements for enhanced connectivity, services, and experiences. The future is bright, and the time to act is now.

The key to success lies in being proactive and forward-thinking. Staying ahead of the curve will undoubtedly ensure thriving in this ever-evolving telecommunications landscape.
