Spread-spectrum radio test kit

If you are unsure if spread-spectrum communications is right for you, you can try before you buy. Campbell Scientific offers a 900 MHz spread-spectrum demonstration kit that allows you to easily test communications from one point to another using the RF407 and RF451 radios. Testing with RF451 radios will be valid for an RF452 network.

Product Line

Frequency Country Used In Transmission Distance

RF452

902 to 928 MHz US, Canada, New Zealand, Australia
  • -Note- Transmission distance assumes line-of-sight and appropriate antenna. Line-of-sight obstructions, RF interference, and antenna type will affect transmission distance.
  • 20.92 to 96.56 km (13 to 60 mi) depending on antenna and line-of-sight

RF407

902 to 928 MHz US, Canada
  • -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 1.61 km (1 mi) with omnidirectional antenna; up to 16.09 km (10) mi with higher-gain directional antennas at ideal conditions

Frequently Asked Questions

Number of FAQs related to Spread-Spectrum Radios: 5

Expand AllCollapse All

  1. Is an individual FCC license required to use a spread-spectrum radio?

    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. 

  2. How does a spread-spectrum radio work?

    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.

  3. Can a spread-spectrum radio be used as a repeater in an RF telemetry network?

    Yes.

  4. Can a spread-spectrum radio be used to connect two computers without a data logger?

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

  5. Is there a recommended RF filter for removing local interference while using a spread-spectrum radio?

    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.
