| Zusammenfassung: | Disclosed is a wireless network system which distributes a time slot by considering each separation distance between gateways, and executes wireless communication between the gateways and end terminals according to an order defined by the time slot. Also, a channel can be determined by using a detected wireless environment indicator. The interference level of the present channel is evaluated. When the inference is excessive, the channel is changed to a channel with the best wireless environment indicator among other channels except the present channel. So, wireless communication can be carried out.
게이트웨이들 각각의 이격거리를 고려하여 타임슬롯을 분배하고, 이 타임슬롯에 의하여 정의되는 순서에 따라 게이트웨이들과 앤드단말들이 무선통신을 수행하는 무선 네트워크 시스템이 개시된다. 또한, 검출된 무선환경 지표를 이용하여 채널을 결정할 수 있으며, 현재 사용중인 채널의 간섭 정도를 평가하고, 간섭이 과도할 경우, 현재 사용중인 채널을 제외한 나머지 채널 중에서 무선환경 지표가 가장 좋은 채널로 채널을 변경하여 무선통신을 수행할 수 있다. |
