The invention refers to a mechanical food treatment processor comprising a driving block topped by a bowl. The fixture includes a first fixing member and a second fixing member magnetically attractable to the first fixing member. The method further comprises determining a user constellation pertaining to information regarding the different user equipments in the set of user equipments and their respective bitrates; and updating a table of IC gain with the measured IC gain in bins corresponding to the determined user constellation. Once the scrambler sequence andor encryption sequence is selected, the packet is transmitted using the selected scrambler and encryption sequences. The well layer comprises InGaN, and the second temperature is lower than the first temperature.
