2.8 FREQUENCY STABILITY Frequency Stability (15.407 (g) ) FCC 15.407 (g) states: “ Manufacturers of U-NII devices are responsible for ensuring frequency stability such that an emission is maintained within the band of operation under all conditions of normal operation as specified in the users manual.” The device uses 20MHz & 40MHz wide channels centered in the allowed 5GHz frequency bands. The required guard bands are implemented per the 802.11 specification.
