• To leverage fiber-optic and radio-over-fiber (RoF) technologies for enhanced performance.
• To achieve seamless integration of diverse wireless standards and frequency bands.

Main Methods:

• Integration of adaptive microwave photonics interfaces and RoF techniques.
• Utilizing all-band radio spectrum from 0.1 to 100 GHz.
• Implementing a 'no-more-cells' architecture with carrier aggregation and seamless handover.

Main Results:

• Improved cell-edge performance in heterogeneous environments.
• Support for coexistence of multiple standards (e.g., 4G, 5G) with continuous coverage.
• Overcoming bandwidth crunch for next-generation communication networks.

Conclusions:

• The proposed multi-tier RAN architecture offers a future-proof solution for wireless communications.
• It enhances system capacity, link speed, and latency while ensuring continuous heterogeneous cell coverage.
