Abstract: Disclosed herein are a tag transmission apparatus and a signal transmitting method thereof. The tag transmission apparatus converts a plurality of data bits into a symbol, which is one of a plurality of symbols, and multiplies the converted symbol by a square-wave having a predetermined frequency to thereby generate a subcarrier signal. Here, in the case in which the plurality of data bits are n (n is a natural number larger than 2) bits, the number of the plurality of symbols is 2n.

Abstract: A method and apparatus having advantages of resolving a phenomenon in which traffic is concentrated on an AP of a wireless network and preventing traffic collision to enhance network efficiency are provided. Thousands or more of nodes included in a wireless network can be connected to the wireless network through a plurality of distributed association nodes, rather than through a single AP, and thus, concentration can be resolved and the wireless network can be effectively operated. Also, by performing distributed association on the basis of a single hop, implementation complexity can be lowered.

Abstract: Disclosed are methods for service discovery in a wireless personal area communication network. A method for service discovery, performed in a terminal, the method comprises performing a passive scan for searching a specific service based on whether to receive a frame including a specific service identifier; and, when it fails to search the specific service, performing an active scan which broadcasts a service discovery request command frame for searching the specific service. Thus, service discovery may be efficiently performed by reducing the operation complexity of the terminal and minimizing the power consumption of the terminal needed for service discovery, without support of a upper layer.
