Radio Configuration
What is a Radio Configuration? What does it stand for?
Definition
Sigfox service operates in the ISM and SRD 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 EMEAI | Zone 2 AMERICAS/ APAC 1 | Zone 3 APAC 2 (Japan, South Korea) | |
Frequency range (MHz) | 862-876 | 902-928 | |
RC | RC1, RC6, RC7 | RC2, RC4 | RC3, 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.
See RC technical details for more information.
Uplink class
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
