Abstract: A method for communicating beacon transmissions from a wireless access point (WAP) to a client transceiver in a wireless local area network (WLAN) system (figure 1) includes obtaining a reference timing for the wireless access point. The sector configuration and the sector timing in the WAP is then determined. A virtual target beacon transmission time (TBTT) for the sector of interest serviced by the WAP is then calculated, as is a channel number of the sector of interest Finally, the method provides for listening for a sector beacon signal from the sector of interest at the virtual TBTT and the calculated channel number.

Abstract: Methods for performing client to client communication in a wireless local ar ea network are disclosed. At an 'n' tier client in the wireless local area network, a signaling message from an 'n-1' tier client is received wherein t he signaling message comprises a first period, a second period, and a third period. Communicating with the 'n-1' tier client during the first period and communicating with the 'n+1' tier client during the third period. At an acce ss point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does no t communicate with the clients during the first period.

Abstract: Un método para comunicar transmisiones de radiobaliza desde un punto de acceso inalámbrico (WAP) a un transceptor de cliente en un sistema de red de área local inalámbrica (WLAN) (figura 1) incluye obtener una temporización de referencia para el punto de acceso inalámbrico; después se determina la configuración de sector y la temporización de sector en el WAP; después se calcula un tiempo de transmisión de radiobaliza objetivo virtual (TBTT) para el sector de interés que recibe servicio por parte del WAP, tal como es un número de canal del sector de interés; finalmente, el método provee escuchar una señal de radiobaliza de sector desde el sector de interés en el TBTT virtual y el número de canal calculado.

Abstract: A method (20,200) and apparatus (10) for detecting and identifying spectr um opportunities, including the steps of communicating a location of at leas t one node (12) to at least one base station (14) (24), transmitting a list of at least one channel from the at least one base station (14) to the at le ast one node (12) (26), and sensing the at least one channel from the list b y the at least one node (12) (34). The method (20,200) also includes the ste ps of determining if the at least one channel is in use, and if the at least one channel is in use, determining the user of the at least one channel tha t is in use (38).

Abstract: Un método y aparato para facilitar una transferencia rápida para suscriptores en una Red Inalámbrica de Área Metropolitana (WMAN - Wireless Metropolitan Area Network) al establecer una asociación fuerte con una primera entidad al enviarle una solicitud de asociación fuerte a la primera entidad y recibir una respuesta de asociación fuerte en respuesta a la solicitud de asociación fuerte y establecer una asociación pendiente con una segunda entidad al enviarle una solicitud de asociación pendiente a una segunda entidad y recibir una respuesta de asociación pendiente proveniente de la segunda entidad. En una modalidad, la asociación pendiente con la segunda entidad puede convertirse en una asociación fuerte.

Abstract: A method for communicating beacon transmissions from a wireless access point (WAP) to a client transceiver in a wireless local area network (WLAN) system (500) includes obtaining a reference timing for the wireless access point (WAP) (502). The sector configuration and the sector timing in the WAP is then determined (503). A virtual target beacon transmission time (TBTT) for the sector of interest serviced by the WAP is then calculated (506), as is a channel number of the sector of interest. Finally, the method provides for listening (507) for a sector beacon signal from the sector of interest at the virtual TBTT and the calculated channel number.

Abstract: A method for transmitting beacon transmissions in a wireless local area network (WLAN) communications system (100) operating on one or more channels includes transmitting a first beacon (C1) using a directional antenna in a first direction (D1) on a first channel. A second beacon (C2) is then transmitted using a directional antenna in a second direction (D2) on the first channel. This process is then repeated such that the first beacon and second beacon after a predetermined beacon interval. The first beacon begins its transmission at a target beacon transmission time (TBTT) and the second beacon begins its transmission in a sequential period defined by an antenna switching time after the transmission of the first beacon.
