Frequency Sets

Below we will demonstrate how to add and configure frequency sets for your Organization.

To create a new frequency set, you'll need to provide:

  • A name for the frequency set.
  • Your license ID - FCC operating ID/callsign (this field is not reported and is for place keeping purposes only)
  • Max Power - The frequency's transmission power.
  • The Bandwidth - You may select 4.54, 7.28, or 11.8 kHz.
  • Control Channels - The channel on which transmission originates. 
  • Data Channels - The channel over which the data packets are sent.

Then select "Create"

  • We recommend adding 3 Control channels and 13 Data channels for optimal performance
  • Antennas are frequency specific- You cannot mix VHF and UHF frequencies with the antennas provided with your goTenna purchase

Bandwidth and throughput

11.8 kHz provides 19.2 kbps throughput

7.28 kHz provides 9.6 kbps throughput

4.54 kHz provides 4.8 kbps throughput

When able, it is best for battery and user performance to operate on 11.8 kHz bandwidth settings

 

Troubleshooting

Problem 1: I’m getting poor to weak range on my goTenna devices.

 

Solution: While range is dependent on many factors, including environmental factors, there are certain settings you can check related to your frequencies to help maximize efficiency:

  1. Am I using the correct channels for my antenna? - Using UHF frequencies with a VHF antenna will make your devices virtually useless.
  2. Is my team on the same frequency spectrum? - If you have one set of frequencies and your team members are using other frequencies you will not be able to communicate.
  3. Am I using appropriate frequencies? While not easy to define, your operations manager should be able to provide you with the frequencies that you should be using. You can use goTenna’s built in Spectrum Analyzer (link) to see what frequencies are being used in my area.

 

Problem 2: I’m getting a Channel spacing error when creating my frequency set

Solution: The goTenna frequency sets must adhere to specific channel spacing requirements

 

11.8 kHz bandwidth setting: .025 Mhz spacing

7.68 kHz bandwidth setting: .0125 Mhz spacing

4.54 kHz bandwidth setting: .00625 Mhz spacing

 

Problem 3: Where can I find my FCC ID/ Why do you need my FCC license ID

 

Solution: FCC licenses can be retrieved from the FCC website

This setting is not monitored and is a placeholder for organizations to manage their licenses
