Abstract: An access point for wireless transmission of packets to user devices includes an application module and a radio module. If the radio module fails to successfully transmit a packet to a user device, the application module takes the packet from its queue and places it in the radio buffer for retransmission. This greatly increases the speed of retransmission. The application module can obtain information on the success of transmitting the packet directly from the radio module.

The optimum path segments are determined conveniently by comparing consecutive entries in a link quality table. Each transceiver may include a direction-agile antenna, which is oriented in the direction to optimize transmission and reception of each received data packet.

Abstract: Systems and methods for a wireless communication device having a switched multi-beam antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna of elements. Groups of the antenna elements cooperate to form active one or more antenna elements while other groups of the antenna elements cooperate to form a reflector for the active antenna elements. This creates a directed transmission or direction of positive gain for the antenna system. The same group of antenna elements can be switched so that other antenna elements cooperate to form the active element while another group forms a reflector for the active elements thereby providing a different direction of positive gain. The system can be used for various wireless communication protocols and at various frequency ranges.

The ground plane can be grounded or capacitively coupled to an existing circuit board or metal surface, allowing for reduced ground plane dimensions.

Abstract: Method for data transmission in a wireless local area network refers to wireless local area networks (WLAN) consisting of a multitude of transceivers capable of establishing communication with one another (i.e. operating in a peer-to-peer mode). Implies the determination of the quality of communication between all transceivers and storage of communication quality data by each of the transceivers. Based on stored data on communication quality, a transceiver operating in the transmission mode transmits information to an addressee by a transmission route that provides for the quality of communication, which is equal to or better than a specified threshold value of communication quality. Stored data are updated periodically. The method improves the quality and reliability of communication for WLAN users (including mobile users) thus increasing the data transmission rate.

Abstract: Refers to networks that are comprised of wire and wireless transceivers connected by wire lines to form a hybrid network. The method implies: transmission of a data packet by one transceivers of the network; reception of an initial fragment of the said packet by a router and storage of the said fragment in a buffer storage; transmission of the stored fragment by the router to an addressee of the network. Reception and storage of a successive fragment of the packet are performed simultaneously with transmission. Then cycles of transmission of the stored fragment and simultaneous reception of a successive fragment are repeated right up to the last fragment, whereupon the last stored fragment is transmitted by the router. The router includes: a wire communication transceiver; a wireless communication transceiver with an antenna system; a processor designed for processing data packets to transmit and receive them by radio channel and wire line; a storage to store a fragment of the data packet.
