## What it is
WFB-NG is a long-range packet radio link that transmits video, MAVLink telemetry, and IP traffic over raw (unconnected) WiFi frames, bypassing the standard 802.11 stack for low latency. It includes smart SIMD-accelerated FEC, libsodium stream encryption, TX antenna diversity, and distributed multi-host operation, commonly used for FPV drone links with Raspberry Pi companion computers.

## Use cases
- stream low-latency FPV video from a drone to a ground station over WiFi
- set up a bidirectional MAVLink telemetry link for a UAV
- build a long-range encrypted data link using raw WiFi packets
- transmit RTP video from a Raspberry Pi camera to QGroundControl
- create a TCP/IP tunnel over a long-distance radio link
- aggregate multiple WiFi receivers on different hosts for a more reliable downlink

## When to choose
- you need a low-latency, long-range video/telemetry link for drones or robots
- you want to use cheap WiFi hardware (e.g. RTL8812au) instead of dedicated radio links
- you need encryption and FEC on an unreliable wireless link
- you fly PX4/ArduPilot vehicles and want a single link for video, telemetry, and control

## When to avoid
- you need a standard IP network with normal WiFi association and routing
- you require regulatory-compliant WiFi operation without checking local laws on raw-frame transmission
- your hardware lacks supported chipsets or patched drivers
- you need high-bandwidth general-purpose networking rather than latency-sensitive streams
