New · preliminary specs
Miniature Ethernet-over-Air Adapter
The EOA-130 is a miniature 57 × 42 mm, 70 g COFDM Ethernet-over-Air module for UAV/USV FPV video, data and C2 links, delivering 50+ Mbps peak throughput and up to 40+ km with directional antennas in the dual-PA 2T2R configuration. Its optimized band spans 2230–2500 MHz (custom 100 MHz–6 GHz) with AES-128/AES-256 encryption. Dynamic channel switching — manual on-the-fly or automatic, signal-quality driven — keeps the link alive in contested spectrum.

[ Why EOA-130 ]
Reach where microwave can’t
The EOA-130 uses COFDM transmit and receive to carry reliable long-range broadband over terrain and non-line-of-sight paths — for UAV and USV FPV video, telemetry and command and control (C2), or for extending a network into the field.
- 01
Long range
Up to 40+ km with directional antennas and the dual-PA configuration.
- 02
Any terrain
Gets through obstacles and non-line-of-sight paths that defeat traditional microwave links.
- 03
Jam-resistant
Custom and non-ISM bands can be configured to step around interference and jammers.
- 04
Drop-in ready
Transparent Ethernet plus UART/S.BUS — plug in with no protocol changes.
[ Range ]
The second amplifier adds a third more range
At every antenna, the dual-PA 2T2R board reaches about a third further than the single-PA board: 6 → 8 km on a 5 dBi omni, 15 → 20 km on a 14 dBi patch, 30+ → 40+ km on a 21 dBi dish with tracking.

[ Anti-jamming ]
Built to keep the link up in contested spectrum
Three mechanisms, used together: move the link across a wide tunable range, switch channels without dropping it, and — optionally — split transmit and receive onto separate bands.
-
Wide tunable frequency range
Relocate the link across a broad band to step away from crowded or jammed spectrum.
-
Dynamic channel switching
Change the operating channel without tearing down the link.
- Manualon the fly
- Automaticsignal-quality driven
-
Separate up / down frequencies Optional
Independent TX and RX bands add robustness against directional, reactive jamming.
[ Topologies ]
One link to a swarm, on the same hardware
The same EOA-130 runs as a point-to-point link, as a star with one ground node commanding several aircraft, or as a self-healing mesh.

- Radio link, two-way

Point-to-point P2P
A dedicated full-rate link between a ground station and a single platform.
Characteristics
- Ethernet and UART both cross the link transparently, with no protocol changes at either end.
- On the aircraft, the flight controller connects on UART and the gimbal camera on Ethernet.
- On the ground, the controller connects the same two ways.
- Radio link, point-to-multipoint
Redrawn from the EOA-130 preliminary datasheet, p3.
Point-to-multipoint P2MP · 1-to-N
Star topology: one master ground node commanding multiple UAV nodes.
Characteristics
- Centralized: one master node, the ground station.
- Multiple slave nodes, one per aircraft.
- All traffic goes through the master.
- The master handles command and control, mission planning, telemetry monitoring and data collection.
- Mesh radio link, multi-hop
Redrawn from the EOA-130 preliminary datasheet, p3.
Mesh network Self-organizing
Decentralized, self-healing multi-hop mesh with no single point of failure.
Take a node out and watch it reroute ↓Characteristics
- Decentralized, with no single point of failure.
- Self-healing: traffic reroutes automatically when a link fails.
- Multi-hop: other aircraft relay traffic beyond the reach of a direct link.
- Scalable: more aircraft can join the network.
[ Self-healing ]
If the straight line is blocked, it takes another hop
The mesh is decentralized and multi-hop, with no single point of failure. When two ends are too far apart, or terrain blocks line of sight, the link does not have to be a straight line — traffic reaches the far end by way of other aircraft. It is self-organizing and self-healing: take any node offline and the rest converge on a new route.
[ Applications ]
