Why certification?

Sigfox Certification 

Sigfox SA requires a Sigfox certification for modulereference design and end products intending to communicate on the Sigfox Network.

It is mandatory for any device communicating on the Sigfox network, to be Sigfox certified:

  • To ensure that Sigfox connectivity is integrated into partner devices with adequate performance level.
  • To maintain a high Quality of Service on the Sigfox network through the conformity of each device to the Sigfox radio specifications (conducted and radiated).

The Sigfox certification will help partners:

  • To achieve the integration of Sigfox connectivity with the delivery of the Sigfox Library, which implements the Sigfox protocol, and with the delivery of sample code.
  • To assess the end-product’s global radiated performances and obtain the Quality of Service targeted for their end product 

Conducted and radiated tests

Two different kinds of testing are achieved when applying for Sigfox certification:

  • Conducted tests to check the Sigfox protocol and the RF modem performance requirements. These tests are performed by Sigfox SA

  • Radiated tests to assess the radiation performances of the end product. These radiation tests will generate a classification level for each end product in uplink mode. This reflects the efficiency of radiated power emitted by the end product. These tests are performed by Sigfox accredited test houses whose list can be found on the Sigfox Partner Network.   

Any module or reference design applying or and passing conducted tests will be receive a Sigfox VerifiedTM label

Any end product applying and passing conducted and radiated tests will receive a Sigfox ReadyTM label.

If the end product is based on a Sigfox VerifiedTM module or Sigfox VerifiedTM Reference design, conducted tests are waived. 

If the end product is a development solution radiated tests are waived

Conducted and radiated tests depend on the radio configuration (RC) defined in each zone of operation.

Radio configuration and zone

Zone 

Sigfox service operates in the ISM and SDR bands worldwide from 862 to 928 MHz.

Global operations are split into three geographical zones: 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

 

Zone 1

EMAEI

Zone 2

AMERICAS/ APAC 1

Zone 3

APAC 2 (Japan, South Korea)

Frequency range (MHz)

862-876

902-928

RC3a, RC3c, RC5

Radio configuration

Within a given Sigfox zone, local regulations may impose specific rules to operate in the unlicensed bands.

Sigfox Radio Configuration (RC) defines the radio parameters in which the device shall operate: Sigfox operating frequencies, output power, spectrum access mechanism, throughput, coexistence with other radio technologies.

 

Each radio configuration includes 4 uplink classes: 0u, 1u, 2u and 3u

Sigfox’s high limit EIRP recommendation is included in each column although regulation sometimes allows more radiated power than the Sigfox recommendation.

Sigfox’s recommendation is set to comply with the Sigfox technological approach of:

  • Low current consumption
  • Balanced link budget between uplink and downlink communication
