A method and system is provided by which packets received from or destined for devices served by a bidirectional signal transceiver such as a distributed antenna system by means of a connected Long-Term Evolution eNodeB are serviced and routed locally rather than being placed arbitrarily on a Wide Area Network. The communications device utilizes a communications device user interface to send andor receive the NFC data from the NFC device when its internal batteries are sufficient to operate the communications device user interface. Separate liners for the trench are used for NMOS and PMOS regions. Next, the first BPSG film is separated into a part of a source diffusion layer side and a part of a drain diffusion layer side, with a gate electrode being a boundary.
