Described herein is an apparatus for inclusion in a station of a wireless network, and a method implemented in a station of a wireless network. The method includes wirelessly receiving data via each of a plurality of antennas (703and 705), the data corresponding to a packet of information transmitted from a remote station, sampling the received data corresponding to the received packet to form data samples for each of the antennas, and determining a measure of signal quality from samples of the received data for each of the antennas. The method further includes selecting (1003) one of the plurality of receive antennas as the antenna for receiving from the remote station according to the determined measure of signal quality.

L'invention concerne un appareil destiné à être inséré dans une station d'un réseau sans fil, et un procédé implémenté dans une station d'un réseau sans fil. Ledit procédé comprend : la réception sans fil de données, par l'intermédiaire d'une pluralité d'antennes (703 et 705), les données correspondant à un paquet d'informations étant transmises depuis une station éloignée ; l'échantillonnage des données reçues correspondant au paquet reçu, ce qui permet de former des échantillons de données pour chaque antenne ; et la détermination d'une mesure de qualité de signaux des échantillons des données reçues pour chaque antenne. Ledit procédé comprend, de plus, la sélection (1003) d'une antenne utilisée ensuite comme antenne de réception de la station éloignée en fonction de la mesure déterminée de la qualité de signaux.
