    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, a number of contending nodes and colliding nodes for a plurality of links of a network is determined. The capacity of each of the plurality of links is determined. A sum of the traffic demand of each of the plurality of links divided the throughput of each of the plurality of links is used to form a cost function for the network. One, or more, of a group consisting of a plurality of frequency assignments, a plurality of transmit powers, and a plurality of clear channel assessment (CCA) values is searched to obtain a global minimum for the cost function. The frequency assignments, transmit powers, and/or CCA values providing the global minimum for the cost function are selected.

    摘要: A method, apparatus, and carrier medium carrying instructions to assign frequency channels and transmit powers for a plurality of access points of a wireless network. The method includes, until there are no more access points to which to assign a transmit power and frequency channel, selecting a next current access point, determining for a set of at least one transmit power for a set of at least one frequency channel a measure of the quality of the sub-network formed by the current access point and all already-assigned access points an evaluation metric indicative of the quality of the sub-network, and assigning to the current access point the transmit power and frequency channel that minimizes the measure of the quality of the sub-network.

    摘要: Systems and methods for adapting IEEE 802.11 wireless communications for environments involving long propagation delays. Improved system throughput and stability are provided. Propagation delays are measured systematically and used to adjust contention timing boundaries and a common time slot duration. This reduces the probability of collision in the CSMA/CA mode of the IEEE 802.11 standard. One particular application is a point-to-multipoint campus bridge network.
