20160057647 | RATE ADAPT ALGORITHM FOR A WIRELESS CONNECTION - In a radio device, an automatic repeat request circuit communicates data messages to remote radio devices at selected data rates. Responses to the data messages are collected and statistics developed about success rates of the data messages at the selected data rates. A current data rate is selected based on the statistics and a packet is transmitted. The data rate can be adapted using the statistics about success rates of the data messages. | 02-25-2016 |

20150181609 | APPARATUS AND METHOD FOR REDUCING INTERFERENCE IN A WIRELESS COMMUNICATION SYSTEM - In a communication system, an access point in communication with one or more stations identifies a first subset of wireless stations from the set of wireless stations. The first subset of wireless stations is identified based on RSSI values for radio frequency signals received from each of the stations exceeding an RSSI threshold. The first subset of wireless stations is assigned to a first reception window. The access point transmits an identifier of each of the subset of wireless stations and an identifier of the reception window via the radio frequency channel. | 06-25-2015 |
20150098456 | MECHANISM FOR WIRELESS COMMUNICATION - In a communication system, an access point in communication with one or more stations is configured to shift the start of transmission of its downlink data. The access point may automatically shift the transmission of the downlink data in response to receiving downlink data transmitted by a neighboring access point. Shifting the start of transmission of its downlink data permits stations to correctly synchronize to the downlink data. The transmission of data may be synchronized to a synchronization event. In some instances, the access point updates its downlink data with a value corresponding to the shift. The access point may not shift the transmission of the downlink data if the signal strength of the received downlink data is below a threshold. | 04-09-2015 |
20140035786 | PATCH ANTENNA - A patch antenna comprises a patch radiator, at least a first connection point for at least a first radio frequency signal, and at least a first feed structure. The first feed structure is arranged to connect the first connection point to at least two feed points on the patch radiator, a first of the feed points being disposed adjacent to a first edge of the patch radiator, and a second of the feed points being disposed adjacent to a second edge of the patch radiator, the first and second edges being on opposed sides of a central region of the patch radiator. The first feed structure comprises at least a first transmission line arranged to connect the first of the feed points to the second of the feed points, the transmission line being disposed in a substantially parallel relationship to the patch radiator. | 02-06-2014 |
