IEEE 802.11b compliant WLAN technology isincreasingly used for cordless telephone services. Often, aWLAN phone is moved during a call. In the present paperwe explore to what extent slow user motion influences thewireless link quality. We conducted extensivemeasurements with speech over commercial WLANequipment using an experimental environment enforcingcontrolled motion. Our experiments show that - incontrast to the common assumption - an increase ofmotion speed can result in a better link quality: The packetloss rate and variance, measured after link-layerretransmissions, decreases. In addition, our measurementsdemonstrate that the modulation type, the maximal numberof retransmissions, the experimental setting, and even thequality of power supply are the dominant influences onlink quality.
