A device and/or method for dynamically adjusting a CCA threshold in an addressable unit that is suitable for communication in a wireless network, the method performed in the addressable unit and comprising autonomously increasing the CCA threshold with successful data transmissions and/or autonomously decreasing the CCA threshold with unsuccessful data transmissions.

Dynamic sensitivity control in 802.11 stations

A concentrator is configured to reschedule a TDMA mesh network in response to an interrupted transmission. The new schedule is calculated by selectively rescheduling transmissions that are scheduled in the same time slot as the interrupted transmission. Transmissions are selected to be rescheduled based on the proximity of the sector of the transmission to the sector of the interrupted transmission. The sectors of the mesh network are defined by neck nodes, where a neck node is a node that can communicate directly with the concentrator.

Methods and apparatus for a TDMA mesh network

A method of identifying an available channel of a plurality of frequency channels defined in a radio frequency spectrum for use by a transmitting station, wherein scanning for an available channel in a frequency spectrum is performed by a scanning method in which a bidirectional search is performed away from an initial channel frequency. The method may include steps to take when a boundary of the spectrum is encountered, and may also take into account existing information concerning channel reservation. A related scanner and radio apparatus is also described.
