    Abstract: A method and a system for communicating personal health data in a Near Field Communication (NFC) environment are provided. An NFC manager sets control information in an NFC Data Exchange Format (NDEF) for providing synchronized communication of personal health data between the NFC manager and an NFC agent. The control information may include a direction flag, a state flag, sequence identifier field, and request/response flag. The NFC manager writes the NDEF format including the control information and payload data into an NFC tag associated with the NFC agent. Subsequently, the NFC manager reads the NDEF record stored in the NFC tag and determines whether the NDEF record is written into the NFC tag by the NFC agent based on the control information in the read NDEF format. Accordingly, the NFC manager repeats the above mentioned steps if the NDEF record includes payload data of the NFC agent.

    Abstract: For a system providing coexistence between a WPAN coordinator and WLAN Access Point (AP), the WPAN coordinator requests WLAN AP for WPAN operation in a selected WLAN channel. The WLAN AP responds with the allocated time limit for which the WPAN operation can be performed. After expiration of the allocated time limit, the WPAN coordinator relinquishes the channel to the WLAN AP. A method addresses the operation of the WPAN system in 2.4 GHz ISM band when a non-overlapping WPAN channel selection is infeasible.
