In a radio network having a low power consumption—a so-called Low Rate Wireless Personal Area Network (LR-WPAN)—a first network unit is arranged above a first physical transmission unit and a first data link unit connected thereto, a first network link having a first switch having echo suppression based on the Low Rate Wireless Personal Area Network being arranged between the first data link unit and the first network unit, and being connected to a second network link having a second switch having echo suppression based on the Low Rate Wireless Personal Area Network via a subsequent connection structure. In this arrangement, this connection structure connects a second network unit to the first network unit for the purpose of communication based on the Low Rate Wireless Personal Area Network.
