Abstract
A user device configured to communicate with a remote device via a Wireless Access Point (WAP) listens on one or more active ports for data sent by the WAP while in a sleep mode. Upon receiving data, the user device identifies the port over which it received the data and determines whether that port is on a list of active ports. If the port is on the list, a controller in the user device wakes the user device from the sleep mode to process the data. If the port is not on the list, the controller discards the received data and leaves the user device in the sleep mode.
