3. While V
4. Description of RSSI measurement with hysteresis mechanism: if the RSSI measurement is higher than the high RSSI level,
DATAMSG is validated (high RSSI level = TRSSI + HRSSI). If the RSSI measure is lower than the low RSSI level, DATAMSG
is inhibited (low RSSI level = TRSSI - HRSSI). Between these two levels, DATAMSG validation depends on the previous
measurement.
Example:
TRSSI = 32 and HRSSI = 4 implies High RSSI level = 26 and Low RSSI level = 28
