Frequency Country Used In Power Output Transmission Distance

RF407

902 to 928 MHz US, Canada 5 to 250 mW (software-selectable)
  • Up to 1 mi with omnidirectional antenna; up to 10 mi with higher gain directional antennas at ideal conditions
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.

RF451

902 to 928 MHz US, Canada, Australia 10 to 1,000 mW (user-selectable)
  • 13 to 60 mi depending on antenna and line-of-sight
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.

RF412

915 to 928 MHz Australia, New Zealand 5 to 250 mW (software-selectable)
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.
  • Up to 1 mi with omnidirectional antenna; up to 10 mi with higher gain directional antennas at ideal conditions

RF422

863 to 870 MHz Europe 2 to 25 mW (software-selectable; assuming 2 dBi antenna gain)
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.
  • Up to 5 km depending on antenna and line-of-sight

RF401A

910 to 918 MHz US, Canada 5 to 250 mW (software-selectable)
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.
  • Up to 1 mi with omnidirectional antenna; up to 10 mi with higher gain directional antennas at ideal conditions

RF411A

920 to 928 MHz Australia, New Zealand 5 to 250 mW (software-selectable)
  • Up to 1 mi with omnidirectional antenna; up to 10 mi with higher gain directional antennas at ideal conditions
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.

RF416

2.450 to 2.482 GHz 50 mW (nominal)

  1. Spread-spectrum radios work by frequency hopping and transmitting at discrete frequencies over part of the unlicensed band, rather than by transmitting over a very wide part of the spectrum as some other devices do.

  2. No. Removing the interference will remove the radio signal. The radio, like all FCC Part 15 devices, is not allowed to cause harmful interferences to licensed radio communications and must accept any interference that it receives.

  3. No. A spread-spectrum radio, like all FCC Part 15 devices, is not allowed to cause harmful interferences to licensed radio communications and must accept any interference that it receives. 

  4. Yes. Two spread-spectrum radios can be used to connect two computers.
