Abstract: A method and apparatus are configured for setting up a channel in a wireless network. The method includes receiving a signal comprising channel information that at least one neighbor AP is using, from the at least one neighbor AP and, setting up the channel of the AP based on the channel information that the at least one neighbor AP is using.

Abstract: An apparatus and a method support bidirectional pairing between devices. A connectable peripheral device is discovered. A list of discovered connectable peripheral devices is displayed. When a peripheral device is selected from the displayed list of the discovered connectable peripheral devices, an indicator operation request message for operating an indicator of the selected peripheral device is generated and transmitted to the selected device. The selected peripheral device operates the indicator according to the indicator operation request message to indicate a connection request from the device.

Abstract: A method and an apparatus for automatically connecting a wireless Local Area Network (LAN) between digital devices and executing an application program based on the wireless LAN, and more particularly, an apparatus and a method for generating device information indicating attributes in a digital device and obtaining attributes of a peripheral device by analyzing device information of the peripheral device. The apparatus includes a device information generation part configured to generate device information including information about attributes by analyzing the attributes of the digital device. The apparatus also includes a device recognition part configured, when receiving device information of a peripheral device, to obtain attribute information of a device corresponding to the received device information. The apparatus further includes a controller configured to control to transmit the device information generated by the device information generation part, to the peripheral device.

Abstract: A method and apparatus for connecting a wireless network in a digital device are provided. The method of connecting the wireless network of the digital device includes receiving a signal from a peer digital device, comparing Receive Signal Strength (RSS) of the received signal with a specified threshold to determine whether the peer digital device is located nearby, if it is determined that the peer digital device is located nearby, establishing a Wireless Local Area Network (WLAN) connection to the peer digital device, and automatically executing an application program that uses the WLAN connection.

Abstract: An apparatus and method for recognizing an indoor zone in which a user is located by using an Earth's magnetic field that is generated naturally instead of the conventional method of combining a magnetic field generator and a magnetic field sensor. The apparatus includes a zone evaluator configured to primarily recognize a location of the portable terminal by using first and second components of an Earth's magnetic field and to finally recognize the location of the portable terminal by using first and second images.

Abstract: A mobile terminal and method for communicating through an optimum communication protocol selected from among a plurality of communication protocols. The mobile terminal includes a communication unit which communicates with a counterpart mobile terminal by a plurality of communication protocols in a network; a signal processor which processes a signal transmitted from or received by the communication unit; a display unit which displays thereon a processed signal; and a controller which controls the communication unit to communicate with the counterpart mobile terminal by an optimum communication protocol among the plurality of communication protocols.

Abstract: A WLAN distributed/opportunistic scheduling (WDOS) method for acquiring a multi-user diversity gain is disclosed. The WDOS method allows a transmitter (i.e., a transmission user) to observe channel conditions of receivers (i.e., reception users), and commands the transmitter to transmit packets to a specific receiver having a relative good channel condition. The WDOS method uses a modified RTS/CTS exchange method to perform the channel probing. If the transmitter broadcasts the BRTS frame, each receiver transmits a CTS frame after the lapse of its backoff period. According to the reception signal strength distribution, the backoff delay time minimizes the number of CTS collisions irrespective of the number of receivers, reduces an amount of channel probing overheads, and maximizes a multi-user diversity gain. The better the relative channel condition, the lower the backoff delay time.
