Sigfox Radio Configurations (RC)

Sigfox has a worldwide coverage network, operating in unlicensed bands worldwide, with radio frequencies ranging from 862 to 928 MHz. Using unlicensed bands enable devices to send their data to the cloud while using little power, at very low cost. 

However, due to local regulations, laws or other operating constraints, the network configuration can differ from one country to the other.

Global operations are currently split into six geographical zones: from RC1 to RC6. More can come as the network adds new countries.

Each zone has a different set of parameters which clearly dimension the device hardware implementation: mainly frequency range, maximum radiated power and radio front end specificities.

Geographical availability

The current six geographical zones are:
  • RC1:
    • Europe: Belgium, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway Portugal, Slovakia, Spain, Sweden, Switzerland, United Kingdom.
    • Overseas France: French Guiana, French Polynesia, Guadeloupe, Martinique, Mauritius, Mayotte, New Caledonia, Reunion.
    • Middle East and Africa: Iran, Kenya, Oman, South Africa, Tunisia, United Arab Emirates.
  • RC2: USA, Mexico, Brazil.
  • RC3: Japan.
  • RC4:
    • Latin America: Argentina, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Panama, Peru.
    • Asia Pacific: Australia, Hong Kong, Malaysia, New Zealand, Singapore, Taiwan, Thailand.
  • RC5: South Korea.
  • RC6: India.

RC technical details

The Sigfox network globally works within the ranges from 862 to 928 MHz. But not all RC require such a wide range of operation.

  • RC1: Works on 868-878.6 MHz with an EIRP of 16 dBm.
  • RC2: Works on 902.1375-904.6625 MHz with an EIRP of 24 dBm.
  • RC3: Works on 922.3-923.5 MHz with an EIRP of 16 dBm. 
  • RC4: Works on 920.1375-922.6625 MHz with an EIRP of 24 dBm.
  • RC5: Works on 922-923.4 MHz with an EIRP of 14 dBm.
  • RC6: Works on 865-867 MHz with an EIRP of 16 dBm. 

How to achieve multi-RC?

Devices can be adapted to one or several Radio Configurations, which are primarily defined by the frequency range that is used, and the radiated power for the device.

Building a multi-RC device implies many aspects that must be taken into consideration:

  • Business case for having a multi-RC device,
  • Available space on the PCB,
  • Energy consumption,
  • Device performance,
  • Modularity and potential evolution,
  • Quantity of devices you expect to build/sell,
  • Manufacturing price, 
  • etc.

All of this also ties up with your technical team: which technology they are used to work with, what their radio skills are, etc.

Because of this, it is most of the time more interesting to build per-RC variations of your device, rather than invest in integrating more than one RC on a single device.

All in all, it all comes down to having a solid business case: whether you can justify the price and additional work or not, or if multi-RC is an explicit request from your client/market.
