BT Explainer: How 5G network slicing works and why telecom firms want it

Indian consumers are now stepping into the future of connectivity with the recent introduction of 5G network slicing by Bharti Airtel through its Priority Postpaid service. This advancement places India's digital framework in line with leading global markets, including the US, Singapore, China, and the UK. Unlike older mobile networks that operated on a shared model, where users experienced identical congestion during peak times, 5G network slicing offers a groundbreaking solution. Telecom companies can now divide a single physical 5G network into multiple virtual lanes, each tailored for specific needs. To visualize this, imagine an airplane with a designated business class section; while the entire cabin shares the same space, each group receives a unique experience without affecting the others. This innovative software-driven architecture significantly enhances the efficiency of network resources, elevating the capacity of the entire system. For instance, during a packed cricket match, while regular users can make video calls on a standard slice, broadcasters can access a dedicated high-bandwidth slice for live 4K transmissions. Meanwhile, emergency services operate on a priority slice, ensuring reliable communication even amidst heavy crowd usage. Beyond providing premium access to select customers, 5G network slicing opens doors to vital applications across various sectors. In healthcare, it ensures low-latency slices for remote surgeries and emergency medical services. The heavy industry can utilize specialized networks for tasks like robotic mining and warehouse automation. Moreover, secure networks for banking transactions and vehicle-to-everything (V2X) communications for smart traffic systems exemplify its versatility. However, this technology's rollout has raised concerns among activists, who fear that monetizing network slices could create a digital divide. They worry that lower-tier prepaid consumers might face inferior online experiences compared to those benefiting from premium slices. Regulatory bodies like TRAI are closely monitoring the performance of these virtual slices to prevent any potential throttling or degradation of standard service. The implications for India's digital future are significant. While the enterprise use of network slicing is widely recognized as a technological leap, extending this model to retail consumers navigates a precarious regulatory landscape. As the telecom market anticipates responses from other major carriers, the scrutiny from New Delhi will ultimately determine whether 5G slicing is hailed as a genuine advancement or critiqued as a corporate maneuver against the principles of an open internet.
