Band n77
3.7 GHz C-Band TDD (3300-4200 MHz)
Global 900 MHz-wide mid-band TDD spectrum encompassing US C-Band and Japanese mid-band allocations.
Technical Explanation
Band n77 spans 3.3 GHz to 4.2 GHz, including the US C-Band (3.7 - 3.98 GHz) and DoD 3.45 GHz auctions. Supporting up to 100 MHz carriers, 30 kHz SCS, and 64T64R Massive MIMO beamforming, n77 provides the optimal balance of multi-gigabit throughput and urban coverage.
Key Functions
- Operating frequency: 3300-4200 MHz TDD (900 MHz total breadth)
- Encompasses US C-Band (3.7-3.98 GHz) and global mid-band allocations
- Dominant spectrum for massive MIMO multi-gigabit commercial deployments
