Abstract: A mesh receiver has a wakeup receiver for reception of a wakeup sequence formed by keyed RF or a sequence of wireless packets and gaps, a transmitter forming low speed RF wakeup sequence to other mesh stations, a mesh receiver for reception of high speed WLAN packets, the transmitter sending a wireless ACK packet in response to a wakeup sequence, the mesh receiver thereafter receiving wireless packets from a remote station, the mesh transmitter sending an ACK, the mesh station thereafter identifying a next hop station, and sending a wakeup sequence to that station, after receipt of an ACK, sending the data, the mesh receiver and mesh transmitter thereafter going to sleep.
