# Wifi model

[Model]

The wifi model simulates a wifi device. There are currently five radio propagation models implemented. The wifi device reports simulated link information for all corresponding nodes within range.

## Worldfile properties

**Simple Wifi Model**

**Friis Outdoor Model**

wifi ( # network properties ip "192.168.0.1" mac "08-00-20-ae-fd-7e" essid "test network" # radio propagation model model "friis" power 30 sensitivity -80 )

**ITU Indoor Propagation Model**

wifi ( # network properties ip "192.168.0.1" mac "08-00-20-ae-fd-7e" essid "test network" # radio propagation model model "ITU indoor" power 30 sensitivity -70 plc 30 )

**Log Distance Path Loss Model**
