The present invention relates to a first node in a wireless communication network. In DL drivers of an MRAM, transistors corresponding to a selected digit line group are made conductive to charge 16 digit lines to power supply voltage and charge a node to a predetermined voltage VP1=VDD\u2212VTH1. Optimum balance between power consumption and speed for each circuit application is achieve by combining high speed C3MOS logic with low power conventional CMOS logic. The system further includes a portal onto which data gathered by the server may be downloaded and with which one can upload information to the server.
