Access points (AP) of wireless LANs are widely deployed to provide mobile access to the Internet. These APs, always powered on and consuming a large amount of power in total, actually are idle during much of the time. Although previous protocol-based sleep-wakeup solutions can partially solve this problem, the large wakeup delay remains a challenge. In this paper we propose a new wakeup transceiver to greatly reduce the wakeup delay so as to realize on-demand wireless LANs. In our model, each AP is equipped with a low-power wakeup receiver and has a unique ID. All modules of an AP in the idle state, except the wakeup receiver, are put into sleep, and are woken up when a node sends a specific ID through the wakeup transceiver. In this design, the wakeup transceiver shares the antenna with wireless LAN device in the same 2.4GHz band. Besides the basic requirement of low-power consumption, there are two additional communication challenges for the wakeup transceiver: (i) how to make the wakeup signal co-exist with WLAN signals, and, (ii) how to ensure a very low false wakeup probability in a scenario where the number of WLAN signals is overwhelming. We suggest using On-Off Keying (OOK) with Manchester codes (MC) and rate constraint for (i) and exploiting the property of OOK+MC in signal recognition for (ii). The extensive simulation evaluation results confirm that the proposed scheme has good performance in both bit error rate and false wakeup probability.
