Abstract
A system contains a wireless station connected to an embedded device by a wired path, with the wireless station being part of a wireless network. According to an aspect of the present disclosure, the wireless station places a receiver (communicating on the wireless network) in power savings mode upon occurrence of a first condition, and restores the receiver to active mode upon occurrence of a second condition. Such transitions between active and power savings modes are employed while receiving data units from a wireless network and providing the data units to the embedded device. In one embodiment, the first and second conditions correspond to a higher threshold and lower threshold for available data in the memory of the wireless station used for buffering not-yet-transferred data units. In alternative embodiments, the conditions are determined based on corresponding express indications by the embedded device.
