# Receive

The Receive page is the ground-station counterpart of the drone's Video
page. It surfaces the WFB-rx adapter the agent uses to pull the air
side's video and telemetry stream.

## Fields

| Field       | Meaning                                                                        |
| ----------- | ------------------------------------------------------------------------------ |
| Adapter     | The RTL8812EU USB Wi-Fi dongle the agent recognised.                           |
| Channel     | Active 802.11 channel (`149`, `36`, etc).                                      |
| Frequency   | Channel center frequency in MHz.                                               |
| RSSI        | Receive signal strength in dBm.                                                |
| Bitrate     | Current downlink bitrate.                                                      |
| Packet loss | Rolling percent over the last second. Color codes shift `ok` → `warn` → `err`. |
| FEC         | Recovered + failed frames since service start.                                 |
| Streams     | Per-stream identifiers the rx is currently demuxing.                           |

## Empty state

When no RTL8812EU adapter is plugged in, the panel shows a hint to plug
one in and tells you the WFB-rx service will start automatically. The
agent's hot-plug watcher rescans every poll cycle.

## Profile gating

Ground-station only. On a drone profile this URL renders the "Not
available on this profile" panel.
