Title (EN) METHOD FOR PREVENTING COLLISION BETWEEN WIRELESS NETWORK STATIONS
(FR) PROCEDE DE PREVENTION DE COLLISION ENTRE STATIONS POUR RESEAU SANS FIL
Abstract:
(EN) The invention relates to a method for preventing collisions between stations (STAl, STA2) able to intervene on accessing a common radio channel in a wireless network with a pint of access (AP). On reception of a header (HEA) transmitted by a first station (STAl), the access point (AP) transmits a copy of the header (HEA).
(FR) La présente invention se rapporte à un procédé de prévention de collision entre stations (STAl, STA2) pouvant intervenir lors de l'accès à un canal radio commun d'un réseau sans fil comprenant un point d'accès (AP). Dès réception d'un en-tête (HEA) émis par une première station (STAl), le point d'accès (AP) émet une copie de l'en-tête (HEA).
