AT&T has been producing AeBS called Flying COWs (Cell On Wings) to provide network connectivity in remote and disaster-hit zones. They are UAVs with a cell site mounted on them. They beam LTE coverage and more recently, 5G
How does it work?
The drone carries a small cell and antenna. It is tethered to the ground to provide continuous power and provides secure fiber data connection. The ground tether ensures unlimited flight time and power but restricts the movement of the COW. The COWs use satellite communication to transmit text, calls, and data.
It can stay on air for up to 24 hours or even up to 16 days provided it meets the daily safety checks
Benefits?
- The COWs can be deployed anytime and anywhere, even in remote areas. The small size of the drone improves its ease of deployment
- Flying COWs can hit altitudes of over 300 ft to provide vast coverage. This is ~500% higher than a traditional COW mast. This enables coverage up to 103.6 sq. km
- Drones are highly scalable and more flying COWs can be deployed readily to expand coverage
- Flying COWs are tough and can resist adverse weather conditions
Where were they used?
| Date | Location | Event |
|---|---|---|
| June 2022 | Missouri, USA | AT&T launched flying COWs to transmit 5G connectivity The first time 5G was transmitted using drones Launch Height - 300 ft Ground Signal Range - 10 sq. miles Signal Type - 5G |
| September 2017 | Puerto Rico | AT&T flying COWs were launched to provide internet access to residents struck by Hurricane Maria The first time an LTE cell site was deployed post-disaster Launch Height - 200 ft Ground Signal Range - 40 sq. miles Signal Type - LTE |
