4.2.6.2.19 Interference Mitigation (VL 900 only)

The Interference Mitigation functionality allows users to configure the unit’s operating channel and noise floor level in order to meet particular requirements regarding throughput and distance. The unit will scan and analyse the 900 MHz spectrum, and, depending on the detected noise levels, it will choose an optimal operating channel and noise floor level.

There are two types of optimization mechanisms available. The unit can either find settings that will ensure the best range for a given throughput or settings that will ensure the best throughput for a given range. Based on the sector’s topography, the unit estimates a theoretical link budget, and matches it against the noise levels detected during the scan to identify the settings that best meet the user’s requirements.

The Interference Mitigation offers a quick and efficient mechanism for setting up access units in the noisy environment of the 900 MHz band, when the operator doesn’t have the time or the expertise required for a full spectrum analysis and channel optimization. For optimal results however, a thorough radio planning performed by a radio specialist is always recommended.

CAUTION

Upon activating the Interference Mitigation, the unit will automatically reset. The unit will enter passive scanning mode for a definite period of time, during which information will be gathered. During the information-gathering period, the unit will not receive nor transmit data. Also, it will not be able to synchronize/associate, meaning that it cannot be managed via the wireless link. At the end of the period, the unit will reset automatically regaining normal operability upon start up.
