Abstract: Technologies for timestamping data packets with forward error correction is disclosed. Alignment markers may be inserted in a data stream in order to assist with synchronization on the receiving end. After insertion of the alignment markers, a start of frame delimiter or other trigger may be detected, triggering a timestamp corresponding to the start of frame delimiter or other trigger. The data and the timestamp are sent to a remote compute device, which may timestamp the data before removing the alignment markers. With this approach, insertion of the alignment markers does not lead to a deviation in the timestamp of the sending compute device or the receiving compute device.

Abstract: An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.
