See the Sigfox Coverage page to view radio presence in the whole world, and the name of all local Sigfox Operators.
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.
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,
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.
Sigfox Monarch provides a unique radio recognition feature of the Sigfox network. It enables devices to manage the radio frequency changes, without any additional hardware such as GPS or Wi-Fi chipset.
This feature enables devices to run seamlessly in all parts of the world, by automatically recognizing and adapting to the local radio frequency standards. It unlocks endless use cases in logistics and supply chain, the consumer industry, and in the automated maintenance for the shipping, aircraft and railway industries.
Radio Configuration can have local peculiarities, which you should be aware of when developing your device.
This sections lists the peculiarities which we are aware of.
RC3c: Managing noisy environment
Listen Before Talk (LBT) is a feature specified by the Japanese regulatory authority ARIB, that mandates devices to verify that the Sigfox operated 200 kHz channel is free of any signal stronger than −80 dBm before transmitting.
Recent field testing in RC3c/Japan revealed that Sigfox devices can be installed in very noisy RF environment that can potentially block message transmission due to the LBT mechanism, and consequently drastically decrease message transmission success rate.
The impact on the Quality of Service can be very serious. The application note below aims at educating device partners on such complex RF environment as well as providing guidance on different technical topics (Hardware, Software, Testing, etc.) to maximize the Message Success Rate.
