Abstract:
WPAN 코디네이터와 WLAN 액세스 포인트(AP) 사이에 공존을 제공하는 시스템 및 방법이 개시된다. WPAN 코디네이터는 WLAN AP에게 선택된 WLAN 채널에서의 WPAN 동작을 요청한다. WLAN AP는 WPAN 동작이 수행될 수 있는, 할당된 시간 제한을 가지고 응답한다. 할당된 시간 제한의 만료 이후에, WPAN 코디네이터는 WLAN AP에 대한 채널을 포기한다. 상기 방법은 중복되지 않은 WPAN 채널 선택이 불가능한 경우, 2.4 GHz ISM 대역에서 WPAN 시스템의 동작을 처리한다.
Abstract:
PURPOSE: An ultra wide-band communication apparatus and a method thereof are provided to stably maintain pulse on-off period for data rates after using an order of modulation for scaling of data rates and to reduce the whole complexity. CONSTITUTION: A differential diffusion encoder(102) encodes a phase of a bit sequence based on a reference bit sequence. A pulse generator(104) generates a plurality of pulses related to the bit sequence by using the encoded phase of the bit sequence. A plurality of the pulses is the same as the bit sequence. A DMPSK(Differential Modulation Phase Shift Keying) modulator(106) generates a signal modulated through modulation of the pulses.

Abstract:
PURPOSE: A method for managing a BAN(Body Area Network) using a coordinator device and a system thereof are provided to manage the BAN with IMDs(Implant Devices) and OBDs(On Body Devices). CONSTITUTION: An MICS(Medical Implant Communication Service) channel is acquired by a MICS transceiver in a coordinator device(310). An indication signal of a wakeup process is transmitted to IMD in a non MICS channel(315). A piconet connection command signal is transmitted to the IMD by the MICS transceiver(320). An approval signal is received by the MICS transceiver(325). The coordinator device and the IMD exchanges the data.
Abstract:
PURPOSE: A method and device for relaxing interference between piconet are provided to reduce interference between piconet when realizing the various existing method between the piconets. CONSTITUTION: An interference detection unit(150) senses interference by piconet. If interference is detected by the interference detection unit, a load adjusting unit(140) applies gaining-losing ratio according to the load control policy corresponding to each traffic level in the piconet. The load adjusting unit determines each traffic section resource allocation amount. The load adjusting unit controls the traffic loads.
