Wireless Wake-up receivers are used whenever a long lifetime and a permanent accessibility are required. The main disadvantage they have is their short range of communication of few meters. We therefore present in this work an infrastructure for a single hop network that makes use of a powerful gateway node that can send out wake-up signals with up to +20 dBm. The end point nodes have an integrated wake-up receiver and consume 3.5μA of current. The wake-up range was measured up to 90 meters in an open air field.
