摘要： In a wireless LAN (WLAN), methods, apparatuses and systems directed to facilitating configuration of a wireless network is provided. According to one implementation of the present invention, sensors are used to collect data associated with locations and other properties of access points of the wireless network. The collected data can then be used to assist in automatically configuring one or more aspects of the wireless network. In some implementations, the collected data can be used to dynamically re-configure the wireless network in real time. According to another implementation of the present invention, location computation mechanisms are used to collect data associated with the location of one or more wireless clients, and the data is used to dynamically adjust one or more radio frequency (RF) coverage maps in real time. The revised RF coverage maps can then be used to re-configure one or more operational parameters of the wireless network. Implementations of the present invention provide many advantages, such as automating the configuration of the wireless network in real time and facilitating network management decisions.

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： In an example embodiment described herein is an apparatus comprising a wireless transceiver and channel selection logic coupled to the wireless transceiver and operable to select an operating frequency for the wireless transceiver. The channel selection logic is configured to reserve a dedicated channel having a special identifier. The channel selection logic is configured to have the wireless transceiver advertise the dedicated service on a normal operating frequency. The channel selection logic is responsive to receiving a request from a wireless device via the wireless transceiver on the normal operating frequency to use the dedicated channel to switch to the dedicated channel and establish communications with the wireless device on the dedicated channel.

摘要： In an example embodiment, a method for synchronizing clocks between a plurality of clocked devices where one of the plurality of clocked devices is not directly synchronized with another of the plurality of clocked devices. Clock offset and a clock drift between a first clock associated with a first device and a second clock associated with a second is directly determined based on signals exchanged between the first and second devices. Clock offset and clock drift between the second clock and a third clock associated with a third device is directly determined based on signals exchanged between the second and third devices. A clock offset and clock drift between the first clock and third clock is determined based on a difference between the clock offset and drift between the first and second clocks and the clock offset and drift between the second and third clocks.

摘要： Described in an example embodiment herein is a technique for generating a heat map representative of a radio frequency environment based on data representative of antenna pattern, antenna orientation, access point height and a path loss model. In particular embodiments, the base heat map can be corrected based on neighbor access point (AP) signal strength measurements, such as received signal strength indications (RSSIs) that are added over a base heat map. The neighbor RSSIs may be adjusted to a point underneath the AP.
