6.6.1 ISM Sub-1GHz Band (Extension Card Frequencies Europe)

The EU Directive 2014 / 53 / EU for the Sub-1GHz Band for the frequency range 25-1000 MHz

for the usage of Non-Specific Radio Equipment (previously known as ISM Band) are used at

the MYNXG products in the following way:

Hardware compliance: According to the above directive in:

▪ Compliance statement of used frequencies, we utilize radio chipsets which are

specified in alignment with EN 300-220-2 V3.1.1 Directive 2014 / 53 / EU 25-1000 MHz

for Non-Specific Radio Equipment.

▪ The FCR3 is utilizing the 863-870 MHz Bands.

Software or system compliance: EDGE FCR 3 is utilizing the following network assignment

technologies in line with the above directive:

▪ Polite Spectrum Entrance / or LBT, we listen before we transmit in the spectrum.

▪ CCA / AFA, we apply methods to analyses the spectrum quality with RSSI and Bit Error

Rate (BER) measurements which are used to identify spectrum validation / conflicts.

In case that such a conflict is detected, we have implemented means inside the cloud

to reconfigure the radio frequency channels of the EDGE FCR 3 used spectrum.

▪ MYNXG sensors managed by the EDGE FCR 3 are always below the duty cycle due to

limited usage to safe power for the sensor.

▪ The Gateway duty cycle for ACKs (acknowledgements) towards the MYNXG sensors

managed is below the duty cycle requirement of the spectrum used and / or in addition

LBT is used to avoid spectrum conflicts with other devices.

GFSK is short for the frequency modulation Gaussian Frequency Shift Keying, DEV is short for deviation, CHF is short for Channel

Filter Bandwidth
