A client computer converts selected content into message formatted content to enable communication of the selected content in a respective message to a picture phone device in a cellular phone network. The means for analysing the data set typically comprises a means for finite element analysis. The light emitting layer is located between the first doped type layer and the second doped type layer. In one example, a fallback access scheme allows the UE to select a secondary carrier frequency for communications with the first base station. The predetermined value is at most two per mill higher than the nominal frequency of the grid and the output power is reduced as soon as any increase of the grid frequency above the predetermined value is detected.
