Type (1 byte): This field MUST be set to 0x0D.
Length (1 byte): This field MUST be set to 0x04.
RSSI (4 bytes): This field specifies an aligned integer that identifies the IEEE 802.11 network interfaces' RSSI. If the actual RSSI value is available, this field MUST be a negative value (the normal range for an RSSI value is -10 through -200), in decibels referenced to a milliwatt (dBm) in network byte order.
-
If the actual RSSI value is not available, but the implementation has some other estimate of the signal strength,<2> this field MUST be a value in the range 0 to 100, where a value of 50 means an "average" link quality and a value of 100 means a "perfect" link.
