Next Generation Fixed Wireless Access (NGFWA)

Overview of Technology Development

New technology developments are enhancing wireless solutions for digital divide initiatives in Washington, DC.
Tarana showcased NGFWA to U.S government officials to deliver broadband to underserved areas.

Fiber-class speeds: Comparable to fiber optics in speed and capacity.
High capacity: Supports many users simultaneously.
Cost efficiency: More affordable compared to traditional methods.
Quick deployment: Can be deployed in months instead of years.
Works in obstructed conditions: Effective even with obstructions and interference.

4G/5G for mobility and Wi-Fi: These technologies are not as effective for scalable fixed access in mainstream markets.

Event Setup: Live three-part demo showing NGFWA in urban obstructed conditions.
Link Deployment: 280-meter link in unlicensed 5 GHz spectrum with a base radio on a four-story rooftop and a remote radio at street level.
Non-line of sight and interference: Setup included 10 laptops and 2 access points on the same channel to simulate interference.
Performance without Key Technologies:
- Initial setup with interference turned off: ~200 Mbps downlink.
- With interference turned on: 25-50 Mbps downlink, showing significant degradation.
Performance with NGFWA Key Technologies:
- Enabling interference cancellation and dynamic beam forming: Increased to stable 450 Mbps downlink.

Economic Practicality: More feasible than fiber in challenging terrains.
Digital Divide: Provides a practical means to close the digital divide in underserved areas.
