摘要： A method for automatic hidden node detection that includes observing frame exchange sequences that conform to a MAC standard such as the IEEE 802.11 standard. The method includes detecting a hidden node upon receiving a response frame without previously receiving the frame causing the response. Similar conclusions may be drawn from longer frame sequences. When a hidden node has been detected with reasonable certainty, a hidden node report is sent to a hidden node manager. In one embodiment, the hidden node manager is centralized, and in another, the management function is performed in a distributed manner. Upon receiving a report, the hidden node manager automatically invokes hidden node avoidance measures by sending one or more action frames. In another embodiment, the hidden node manager turns on a hidden node mitigation method. In the case of the IEEE 802.11 standard, the hidden node manager turns on the IEEE 802.11 hidden node mitigation method based on RTS/CTS exchange.

摘要： An apparatus in a node of a wireless network for setting the data rate for sending data to a remote node, and a method for setting the data rate. The method includes receiving a packet from the remote node, determining a measure of signal quality for the received packet; and selecting the data rate for communicating to the remote node according to at least the determined signal quality. The measure of signal quality is a measure of the EVM of the received packet. One implementation conforms to one or more variants of the IEEE 802.11 standard that uses OFDM packets.

摘要： In an example embodiment, packet encapsulation is employed to facilitate bridging between bridge ports that do not reflect frames (such as 802.1 compatible bridge ports) and bridge ports that do reflect frames (such as 802.11 compatible clients). Packets from a wireless access point may be sent twice, once with a predefined multicast address for processing by 802.11 clients contained in bridges, and once with the original destination address. In particular embodiments, additional means may be employed to minimize the circumstances where packets are duplicated.

摘要： Systems and methods for providing a fully differential amplifier performing common-mode voltage control having reduced area and power requirements are disclosed. The amplifier disclosed comprises an additional input stage at the amplifier input which senses the common mode voltage of the amplifier's inputs and applies internal feedback control to adjust the output common-mode voltage until the input common-mode voltage matches a target voltage and thereby indirectly set the output common-mode voltage. Furthermore the internal common-mode control can be implemented in such a manner as to provide a feed-forward transconductance function in addition to common-mode control if desired. Moreover it is possible to use feedback from other amplifier stages in an amplifier chain to implement common-mode feedback.

摘要： A method and apparatus for synchronizing a local clock value in a wireless receiver receiving a data unit containing synchronization information. The method includes receiving a first data unit containing synchronization information, extracting the synchronization information from the received first data unit, copying a local free-running clock at a known reference point in time relative to the time the first data unit was received to generate a local timestamp; and calculating an offset to the free-running clock using the extracted synchronization information and the local timestamp, the calculating in non real-time, such that the sum of the calculated offset and the value of the free-running clock provides a local clock value that is approximately synchronized in time. The apparatus implementing the method is part of a node of a wireless station, and provides a time synchronization function, typically at the MAC layer.
