摘要： Techniques are provided for selecting channels for a wider bandwidth operation mode of a wireless network, such as wireless network that operates in accordance with the IEEE 802.11n amendment. Alignments of so-called primary and secondary channels are selected to mitigate interference. Interfering sources, such as other transceivers or external interferers, or the energy from their transmissions, are identified and channels are selected. The selected channels are analyzed to determine whether primary-secondary channel assignments for the selected channels are feasible.

摘要： A technique is provided to enable a ranging-enhanced communication device that operates according to a legacy communication protocol to transmit a ranging waveform that is not defined in, or part of, the rules of the legacy communication protocol. In one embodiment, a ranging-enhanced communication device that is to transmit the ranging waveform generates information representing a time interval within which to wirelessly transmit a ranging waveform that is not defined by a legacy communication protocol. This information is encoded into a field of a frame that is formatted according to the legacy communication protocol to protect the time interval from transmissions by legacy communication devices that operate according to the legacy communication protocol. The ranging-enhanced communication device transmits the frame and transmits the ranging waveform during the time interval following the frame.

摘要： A device whose location is to be determined (target device) generates a plurality of frames (messages) and time of departure (TOD) timestamp information indicating when the target device transmits the plurality of frames in a sequence or burst. The target device transmits the plurality of frames and the TOD information, wherein the plurality of frames are transmitted such that at least two of the frames are on different radio frequency (RF) channels. Within a sequence or burst (or across multiple sequences or bursts), multiple widely spaced transmissions on the same channel are included to allow for estimation of the crystal frequency offset of the transmitting device. The TOD information included in the transmitted packets allows devices that receive the packets not to change their channels of operation solely for the purpose of receiving packets from the device to be located.

摘要： At a plurality of first devices, wireless transmissions are received at different locations in a region where multiple target devices may be emitting. Identifier data associated with reception of emissions from target devices at multiple first devices is generated. Similar identifier data associated with received emissions at multiple first devices are grouped together into a cluster record that potentially represents the same target device detected by multiple first devices. Data is stored that represents a plurality of cluster records from identifier data associated with received emissions made over time by multiple first devices. The cluster records are analyzed over time to correlate detections of target devices across multiple first devices.

摘要： Methods, apparatuses and systems directed to partitioning access points into two or more network access layers, such as overlay and underlay network access layers. According to one implementation of the present invention, a wireless network management system partitions a set of wireless access points into an overlay network for low-functionality clients and an underlay network for high- functionality clients. As described in further detail below, each of the overlay and underlay networks provides a class of network service, where each class of network service differs relative to at least one attribute (e.g., type of 802.11 access, data rates, High-Density, Quality-of-Service, encryption, compression, etc.). For didactic purposes, the overlay network is also referred to as the overlay network service layer (NSL) and the underlay network is referred to as the underlay NSL. In one implementation of the present invention, a partitioning algorithm is used to partition wireless access points into overlay and underlay networks. As described in further detail below, the partitioning algorithm, in one implementation, automatically assigns access points to the overlay and underlay networks based on the coverage needs of each network and the coverage parameters of each access point. In one implementation, the partitioning algorithm can be configured such that the overlay network provides maximum coverage for low-functionality clients, and the underlay network enables maximum performance for high -functionality clients.
