Typical TeensyWiNo radio ranges

The TeensyWiNo radio range depends on:

  • the antenna,
  • the transmission power and the modulation,
  • the environment: outdoor, indoor (walls, etc.).

See the TeensyWiNo antenna tutorial to choose the appropriate antenna.

You may also set the appropriate txPower and modulation. With the following configuration, a indoor range of 30m can be achieved with the DIY spring antenna

rf22.setTxPower(4);
rf22.setModemConfig(RH_RF22::GFSK_Rb125Fd125);
rf22.setFrequency(434.0, 0.05);

If you use narrow bandwidth such as GFSK_Rb2_4Fd36, a range for 200m can be achieved, even in indoor environments.
