摘要:
The present invention offers significant improvements in the performance of a radio receiver operating in an environment with high desired band interference. The present invention comprises a high selectivity RF circuit that is located between the antenna and the radio receiver, and utilizes superheterodyne technology to filter adjacent channel interference in the desired band frequency spectrum. This type of interference is problematic for IEEE 802.11 radio receivers that are implemented with the popular direct conversion radio receiver architectures.

Multi-directional antenna apparatuses, which may include phased array antennas and/or arrays of multiple antennas, and methods for operating these directional antennas. In particular, described herein are apparatuses configured to operate as an access point (AP) for communicating with one or more station devices by assigning a particular directional beam to each access point, and communicating with each station device using the assigned directional beam at least part of the time. Methods and apparatuses configured to optimize the assignment of one or more directional beam and for communicating between different station devices using assigned directional beams are described. Also described are methods of connecting a radio device to an antenna by connecting a USB connector on the radio device to a USB connector on an antenna and identifying the antenna based on a voltage of the ground pin on the antenna's USB connector.
摘要:
Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

Embodiments of methods and apparatuses for resource allocation in a wireless communication system are disclosed. In one embodiment, a method of wireless communication comprises obtaining data to be transmitted over a plurality of sub-channels in a wireless communication environment, determining channel conditions associated with the plurality of sub-channels, scheduling the data to be transmitted according to the channel conditions associated with the plurality of sub-channels to form scheduled data for transmission, and transmitting the scheduled data to one or more receivers via the plurality of sub-channels. The method of determining channel conditions associated with the plurality of sub-channels comprises determining interference observed at each sub-channel in the plurality of sub-channels.

One embodiment of the present invention provides a radio assembly. The radio assembly includes an antenna housing unit that houses a pair of reflectors which are situated on a front side of the antenna housing unit, a printed circuit board (PCB) that includes at least a transmitter and a receiver, and a backside cover. The PCB is situated within a cavity at a backside of the antenna housing unit and the backside cover covers the cavity, thereby enclosing the PCB within the antenna housing unit. One embodiment of the present invention provides a user interface for configuring a radio. The user interface includes a display and a number of selectable tabs presented on the display. A selection of a respective tab results in a number of user-editable fields being displayed, thereby facilitating a user in configuring and monitoring operations of the radio.

Computer implemented methods and systems for assisting a user to select one or more codes from a set of available codes to categorize a record. The method includes (a) receiving information on a record to be categorized; (b) determining a set of multiple candidate codes to suggest to the user that is a subset of the set of available codes having a greater likelihood of accurately matching the applicability criteria for the codes for the record than other codes, the set of candidate codes including candidate code(s) selectable by the user to be assigned to the record among other possible candidate codes; (c) presenting the set of multiple suggested candidate codes to the user for assessment; (d) receiving a user selection input of a code or codes to be associated with the record; and (e) assigning the selected one or more codes to the record to categorize the record.

A programmable RJ45 jack is disclosed. In some examples, the RJ45 jack may be configured to emit a user-defined color at the presence of a user-selectable data-link characteristic. In some examples, any number of programmable RJ45 jacks may be included within a device, such as an ethernet switch. A configuration database describing a relationship between data-link characteristics and colors may be downloaded to a device that includes the programmable RJ45 jack.

摘要:
Multi-radio antenna apparatuses and stations for wireless networks including multiple radios coupled to a single transmit/receive antenna, in which the antenna is highly synchronized by an external (e.g., GPS) signal. These multi-radio antenna systems may provide highly resilient links. Synchronization may allow these apparatuses to organically scale the transmission throughput while preventing data loss. The single transmit/receive antenna may have a single dish or a compound (e.g., a single pair of separate transmitting and receiving dishes) and connections for two or more radios.
