A system for interference mitigation through carrier aggregation may include one or more processors and a memory. Logic in the first network element generates a first knowledge digest encoding the first configuration information into a fixed length bit array. The total dispersion slope of said fiber at 1550 nm is less than 0. The NFC unit communicates with the mobile communication terminal body through the serial communication unit and communicates with the outside via non-contact NFC. Each coil is selectively activated by activating a unique pair of a high side gate and a low side gate, thus reducing the total number of gates required.
