When AW ⁇ is less than zero, it indicates that the downlink bandwidth needs to be increased. When AW ⁇ is equal to zero, the downlink bandwidth does not need to be changed. If it is greater than zero, it means that the uplink band can be reduced. When Afiffra is less than zero, it means that the boost port is required to be uplinked.
