Page 4: Operation Principle
Then during the operation, there are 03 cases of sending data to base station: 1. When the sensor sampling time interval is reached, the Sigfox node will read the data from Input or sensor and performing the calculation. After that it will check calculated value with alarm thresholds. If the calculated was out off the threshold values (Lo or Hi), called alarm, and the number of times of alarm did not pass the limit of number of alarms, then it will send data to Base station immediately;... -

The RF transmit power will be automatically set as the max value as allowed by the Zone. 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, etc. - Page 7 The Sigfox network globally works within the ranges from 862 to 928 MHz. But not all RCs require such a wide range of operation. Uplink center frequency (MHz) 868.130 902.200 920.800 Downlink center frequency (MHz) 869.525 905.200 922.300 Uplink data rate (bit/s)

- Page 10 5.5 Process of measurement When the sensor sampling time interval is reached, for example 2 minutes, the Sigfox node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement. Depends on the type and characteristic of external sensor, the sensor will take a certain time to finish the measurement.

To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Sigfox sensor and Base station. In real life, there may be no LOS condition. However, the Sigfox sensor still communicate with Base station, but the distance will be reduced significantly. -
