Abstract: A system and method are described for binding together a plurality of wireless data communications channels, whereby an aggregate throughput improvement is realized. A master channel amongst the channels to be bound is compatible with existing standards-based wireless data communications equipment. The master channel serves to perform MAC association and flow control. Aggregate throughput is improved by sending and receiving either multiple sets of separately encoded packets, commonly encoded packets or redundantly encoded packets.

Abstract: To avoid interference with radar systems in the 5GHz, wireless devices detect radar and vacate any channels currently used by the radar system. In a channel switching technique, if the new channel is radar-exempt, then normal operation commences on the new channel. If the new channel is non-radar-exempt, then normal operation commences on a temporary radar-exempt channel and an aggregate background scan can be performed on the new channel. If no radars are detected using the aggregate background scan, then operation is switched from the temporary channel to the new channel.

Abstract: Systems and methods to provide ordered transmission of data packets to multiple destinations are presented. A transmission device includes a transmitter, a data packet ordering unit, a state table, and a transmit management interface such as a hardware/software unit. The state table stores a transmit block status of each destination. The transmit management interface is coupled to the transmitter and analyzes data packets. The transmit management interface determines whether to transmit a data packet targeted to a particular destination or to block transmission of data packets to the particular destination by examining the transmit block status of the particular destination from the state table.

Abstract: A wireless communication system implements a calibration mode by which individual nodes in the system can determine which other nodes in the system are physically close to them and therefore can be reached with less than full transmitting power. Nodes which can communicate with one another via low power can form a low power constellation (a subset of the complete network) whose nodes can communicate directly with one another using this low power arrangement. The direct communication mode may additionally be used by itself. In another mode, the nodes in the system can communicate amongst themselves via bridges - other, non-access point nodes - to lessen the load on the access point or to accommodate environmental or other conditions. Various ones of these modes may be combined into a predetermined cycle of communication modes to help the physical layer accommodate various types of data handled by the network using beacons or another coordinating technique. Overhead in the form of packet retransmission may be reduced by interpolating to recover lost packets rather than retransmitting them.

Abstract: A Hardware MAC (Media Access Control) unit implements time-critical functions according the 802.11 standard for telecommunications, thereby enhancing system performance. The MAC layer includes three sub-layers: MLME (MAC Sublayer Management Entity), which connects the MAC unit with the host CPU, FTM (Frame Transition Manager), which connects the MAC unit with the network, and FLPM (Frame Level Protocol Manager), which internally connects the MLME sub-layer with the FTM sub-layer. In particular, the FLPM manager includes time-critical and non-time-critical functions that are customarily implemented in software on the MAC by a MAC CPU (Central Processing Unit). The hardware MAC implements time-critical FLPM functions in hardware on the MAC and implements non-time-critical FLPM functions in software on the host CPU so that requirements for processing software on the MAC preferably may be altogether eliminated or alternatively may be substantially reduced.

Abstract: A mixing apparatus includes a Gilbert cell connected to a first load and a second load. In one embodiment each load contains transistors that are configured as a diode and a triode, where these circuits are additively combined to achieve substantially linear voltage-current characteristics over a predetermined range. The mixing apparatus takes two pairs of differential inputs and produces a pair of differential outputs. Because of the substantial linearity of the loads, the inputs and outputs of the mixing apparatus are acceptable over a relatively large range of input settings. In other embodiments each load may contain a transistor configured as a triode and a resistor, where these circuits are likewise additively combined to achieve substantially linear voltage-current characteristics over a predetermined range.

Abstract: A method for communicating among nodes in a network includes determining, by a transmitter, a first frequency band and at least a second frequency band to be used for communicating data packets, wherein a maximum allowable power spectral density in the first frequency band is greater than a maximum allowable power spectral density in the second frequency band. The method also includes adjusting power spectral density for a first group of frequencies in the first frequency band such that the adjusted power spectral density of the first group does not exceed the maximum allowable power spectral density of the first frequency band and a quantization noise introduced by the transmitter is less than a threshold value for a signal transmitted in the second frequency band. The method further includes modulating at least a portion of a data packet transmitted by the transmitter to at least a first receiver in accordance with the adjusted power spectral density.

Abstract: An embedded system (100) optimally operates with minimal power consumption without sacrificing performance. Power consumption can be reduced by independently and dynamically controlling multiple power partitions (101, 102, 103, 104), wherein components within a partition can have the same power profile. States of operation can be programmably defined in a table (300) a enforced using hardware. Voltages in the table (300) can be dynamically updated during a runtime of the system using a timing feedback module (504), which is connected to a critical path in a partition. The timing feedback module (504) can output a vector (507) that indicates the timing margin for that critical path. Using this timing margin, software can increase or decrease the voltage optimize power consumption of that partition.
