Spectrum Sharing
Spectrum sharing allows multiple operators or technologies to dynamically use the same frequency bands instead of relying on exclusive licensed allocations. Approaches include CBRS (Citizens Broadband Radio Service), dynamic spectrum access (DSA), and database-driven coordination. This flexibility is critical for 6G, where massive bandwidth demands will exceed traditional allocation models.

Millimeter wave (mmWave) refers to radio frequencies between 24 and 100 GHz, characterized by short wavelengths (1–10 mm). In 5G, mmWave enables high-capacity urban hotspots with speeds exceeding 1 Gbps
Sub-terahertz frequencies (100–300 GHz) are candidate bands for 6G and 7G networks. They offer massive bandwidth — up to 10 GHz per channel — enabling multi-gigabit wireless links
Open RAN is an industry initiative to disaggregate traditional base station hardware and software into interchangeable, multi-vendor components connected via open interfaces. The goal is to reduce vendor lock-in, lower costs, and accelerate innovation by allowing operators to mix and match radio units, distributed units, and centralized units from different vendors.
