Understand how the PDCCH control region in 4G LTE evolved into the flexible CORESET design in 5G NR. Explore structure, bandwidth parts (BWP), and how NR improves control channel efficiency.

Explore how 5G NR revolutionizes radio resource management with CORESET and BWP, replacing LTE’s static control region for higher flexibility and spectrum efficiency.

Discover how fiber optic communication systems convert electrical signals into light pulses to deliver ultra-fast, reliable data transmission across long distances.

Discover the roadmap from 3GPP Releases 15 to 18 and how 5G Advanced is set to transform industries, networks, and user experiences with smarter, faster, and more efficient connectivity.

Explore how 5G physical channels and signals form the foundation of wireless communication between gNodeB and user equipment (UE). Understand their roles, structure, and importance in the 5G NR architecture.

The 5G waveform has evolved from OFDMA-based transmission in Release 15 to high-frequency adaptations in Release 17 and beyond. Learn how subcarrier spacing and new waveform designs are shaping the future of wireless connectivity.

The 5G waveform continues to evolve through 3GPP releases—from OFDMA-based designs in Release 15 to advanced high-frequency waveforms in future bands above 71 GHz.

5G operates across a vast spectrum from 300 MHz to 100 GHz. Learn how low, mid, and high-frequency bands—sub-6 GHz, cmWave, and mmWave—shape 5G’s speed, coverage, and capacity.

5G NR numerology defines how frequencies, symbols, and scheduling intervals adapt to different 5G use cases. Learn how subcarrier spacing, cyclic prefix, and symbol duration shape network performance.
