Abstract: The present invention relates to the connection of subnets which operate on different frequency channels and are connected by wireless forwarder stations. According to the present invention, a forwarding station periodically switches to the other frequency channel to remain there for a pre-defined presence duration, whereby jitters of the presence time caused by overlapping packet transmissions are compensated. According to the present invention, a presence and absence time of the forwarder station in the respective subnet is indicated by using signals relating to a power saving mechanism.

Abstract translation: 本发明涉及在不同频率信道上工作并由无线转发站连接的子网的连接。 根据本发明，转发站周期性地切换到另一个频道以保留在那里用于预定义的存在持续时间，由此补偿由重叠分组传输引起的存在时间的抖动。 根据本发明，通过使用与省电机构相关的信号来指示各个子网中的转发站的有无时间。
