Different possibility of 6G Architecture
India 
improved its mobile broadband speed from 118th to 39th globally via 5G, fiber, and digitization. With the advent of 6G deployment by 2026, and eye to secure spot in top 5 globally. Below are different possibility of 6G Architecture based on use cases & needs.
1) Last Mile Connectivity is Network
To provide services/network that connects the service provider’s infrastructure to end-users location, even in remote / less accessible areas.
Why it is Different from 4G/5G ? - 4G/5G primarily aim was to provide speed & capacity, 6G aim is to provide ubiquitous connectivity.
2) Cell Mesh / Cell Free
It eliminates traditional cell boundaries by involving large number of distributed antenna units that together serve users without predefined cell boundaries, which helps in reducing interference & maximizes spectral efficiency.
Why it is Different from 4G/5G ? - In 4G we had traditional cell towers, In 5G we introduces Pico | Small | Light cells for better coverage and both 4G & 5G had cell boundaries, but in 6G with cell-free architecture it provide seamless connectivity with ultra-low latency & high reliability, especially in dense urban areas and high-mobility scenarios with reduce over-head traffic & interference.
3) Super - Specialized Slicing
Creation of multiple virtual networks on single physical infrastructure with fully mature end-to-end slicing, later optimizing it for specific use cases to enable Industry 4.0/5.0 and Enterprise Network use cases.
Why it is Different from 4G/5G ? - 4G = “No” slicing capabilities, In 5G we have limited slicing capabilities, but in 6G we will have fully matured slicing, which will offer more granular & efficient resource allocation to support wider range of use cases.
4) RAN – CORE Convergence
Integration of RAN & Core into a single, unified architecture, which allows for more efficient data processing & management closer to the user.
Why it is Different from 4G/5G ? - In 4G & early 5G - RAN & Core functions were separate. In 5.5G they integrated them closer and for 6G we have tighter integration of RAN and Core functions to reduce latency, enhance data processing capabilities, & support real-time applications.
