A system, method, and apparatus are provided for establishing a wireless network connection between a mobile terminal and an electronic apparatus by using a near field communication network. At least one electronic apparatus is connected to the near field communication network. A mobile terminal is connected to the near field communication network, exchanges information with the at least one electronic apparatus for a wireless communication network connection through the connected near field communication network, and establishes the wireless communication network connection with the at least one electronic apparatus based on the exchanged information.

In the receiving side MAC layer timestamping approach, the MPDU structure is changed by adding an extra timestamping field. When a MPDU packet is generated, a captured receiving timestamp is written into the MPDU's timestamp field. The MPDU packet is then forwarded from the PHY to the MAC layer of the wireless sensor node. In the MAC layer, the receiving timestamp is further processed and inserted into a corresponding field of the time synchronization message, which is in turn transmitted to a Time Synchronization module. In the sending side MAC layer timestamping approach, the sending timestamp is captured immediately before the time synchronization message is written into TxFIFO.
