Abstract: Antenna diversity for beacons. An access point device may include multiple antenna arrays. A series of beacons may be transmitted using each of the antenna arrays in sequence. The beacons may include configuration information usable by wireless devices to determine when to respond to the beacons. The access point may receive responses during a series of response periods, using each of the antenna arrays.

Abstract: Techniques are disclosed for coding video in the present of transmission errors experience in a network. When a new coding unit is presented for coding, a transmission state of a co-located coding unit from a preceding frame may be determined. If the transmission state of the co-located coding unit from the preceding frame indicates an error, an intra-coding mode may be selected for the new coding unit. If the transmission state of the co-located coding unit from the preceding frame does not indicate an error, a coding mode may be selected for the new coding unit according to a default process. The new coding unit may be coded according to the selected coding mode, and transmitting across a network. These techniques find ready application in network environments that provide low latency acknowledgments of transmitted data.
