# Parallel Wi-Fi PTP4L

This experiment bundle is the common home for parallel Wi-Fi PTP4L runs across
the three current WLAN modes:

- `infra`
- `adhoc`
- `mesh`

Each mode keeps its own `ptp_config/` and `logs/` folder so that later mesh
variants can be added without changing the runner layout.

Current default node groups:

- `infra`: `apu00`, `apu01`, `apu02` with `apu01` as master on `wlan0`
- `adhoc`: `apu10`, `apu11`, `apu12` with `apu11` as master on `adhoc0`
- `mesh`: `apu20`, `apu21`, `apu22` with `apu21` as master on `mesh0`

The main runner lives next to the mode folders:

```bash
./run_parallel_wifi_ptp4l.py 120
./run_parallel_wifi_ptp4l.py 120 --experiments infra,mesh
```

Startup order in the runner:

1. `phc2sys` on each node: PTP interface PHC -> `eth0`
2. `receiver_hwts_logger` on each node
3. local `reference_broadcast/broadcaster` on the testbed server
4. `ptp4l` on the selected WLAN interfaces
