Appl. No.:

10/698588

Inventors:

Daniel Joseph Lyons - Chippewa Lake OH, US
Brian Hart - Wollstonecraft, AU

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04B017/00
H04B001/10
H04B015/00
H04B001/06
H04B007/00

US Classification:

455 6713, 4552771, 4552772, 455 65

Abstract:

Describe herein is an apparatus for inclusion in a station of a wireless network, and a method implemented in a station of a wireless network. The method includes wirelessly receiving data via each of a plurality of antennas, the data corresponding to a packet of information transmitted from a remote station, sampling the received data corresponding to the received packet to form data samples for each of the antennas, and determining a measure of signal quality from samples of the received data for each of the antennas. The method further includes selecting one of the plurality of receive antennas as the antenna for receiving from the remote station according to the determined measure of signal quality.

John Matthew Swartz - Lithia FL, US

International Classification:

H04W 16/10
H04W 74/08

Abstract:

In one illustrative example, a device configured for use in a wireless local area network (WLAN) may cause a spatial reuse (SR) adjustment to be performed based on data received from a multi-user receiver procedure for the blind detection and demodulation of colliding packets from multiple stations. This procedure may be performed by one or more access points (APs) and/or distributed sensor nodes, each having such a multi-user receiver. The procedure may involve receiving and decoding, over a channel, a first spatial stream from a first device of a first base service set (BSS) color; simultaneously receiving and decoding, over the channel, a second spatial stream from a second device of a second BSS color (i.e. an overlapping BSS or “OBSS”); and calculating a signal-to-interference ratio (SIR) based on signal levels associated with the streams. The SR adjustment may involve adjusting an OBSS Packet Detect (PD) (OBSS-PD) threshold.

Inventors:

Daniel Joseph Lyons - Medina OH, US

International Classification:

H04L 27/26
H04B 7/04

Abstract:

Embodiments of the present invention relate to methods and systems for simultaneous communication with multiple wireless communication devices. In some embodiments, a method for simultaneous communication with multiple wireless communication devices includes receiving, using a plurality of antennas at a first wireless station, a plurality of packets, comprised of orthogonal frequency division multiplexing (OFDM) wireless signals, transmitted simultaneously from a plurality of other wireless stations wherein each of the simultaneously transmitted packets includes a plurality of frequency tones, frequency domain transform the received packets, grouping frequency domain transform outputs for each subcarrier, determining a difference between subcarrier groups formed over different sample sets, and determining a set of weights for each subcarrier, wherein the weights are selected such that the first wireless station can at least one of detect or demodulate the received plurality of packets.

Inventors:

Daniel Joseph Lyons - Medina OH, US

International Classification:

H04L 29/06
H04L 12/26

Abstract:

Methods and apparatus for collaborative environment sharing comprise transmitting a video stream captured by a local device to one or more remote devices, receiving, at the local device, remote visual cue data related to the video stream from the one or more remote devices, wherein the remote visual cue data comprises one or more visual cues associated with objects identified in the video stream by users of the one or more remote devices, transforming the visual cue data to correctly position the one or more visual cues with an updated location of the objects in the video stream at the local device and superimposing the one or more visual cues over the video stream displaying on the local device continuously as a user of the local device relocates the local device.
