Abstract
Embodiments herein describe BKDs that can transmit reply messages using different frequencies than the frequencies of wireless transmissions they receive which can reduce collisions in a Wi-Fi environment. In one embodiment, when transmitting power to be used by a BKD to transmit a reply message, an access point (AP) also includes an parameter that affects the frequency used by the BKD when transmitting its signal. For example, the AP can direct the BKD to use a frequency in a channel that is not used by other Wi-Fi Devices. The BKD can be equipped with a frequency filter that can shift the carrier frequency of the BKD response (compared to the carrier frequency of the energy-bearing signal) allowing the response signal to be transmitted on a different frequency than the one which was received.
