20140146808 | POWER EFFICIENT TUNNELED DIRECT LINK SETUP APPARATUS, SYSTEMS AND METHODS - Apparatus, systems, and methods disclosed herein operate to provide wireless communication between personal mobile communication (PMC) devices. 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. | 05-29-2014 |

The custom name may be based on the type of device, location, services, and/or other information about the headless device. The custom name is introduced to the communications network in association with a network address of the headless device. In some embodiments, forged messages based on conventional network protocols may be used to associate the custom name with the network address of the headless device. | 02-19-2015 |
20150052255 | MINIMIZING COVERAGE HOLES IN A COMMUNICATION NETWORK - Access point functionality of a network device may be disabled, resulting in a coverage hole in a communication network and affecting performance of a client device. Various techniques can be implemented for detecting and minimizing coverage holes. In one embodiment, the network device can selectively establish a communication link with the client device depending on whether the client device is in a coverage hole and depending on whether the client device can detect another access point in the communication network. In some embodiments, the client device can determine that it is in a coverage hole in response to detecting a reserved SSID and can accordingly notify a central coordinator of the communication network.
