LQ = The percentage of packets that are succesfully sent from youself to the neighbour ILQ = The percentage of packets that succesfully are sent from your neighbour to yourself also often called NLQ
ETX = Expected Trasnmission count = How many trasnmission attempts are required to get packets through = 1 / (LQ*ILQ)
