Abstract

La présente invention concerne un procédé et un dispositif de transmission de données sans fil. Le procédé de transmission de données sans fil consiste : à recevoir une demande de service envoyée par un terminal sans fil ; à acquérir la performance de transmission d'un canal sans fil entre le terminal sans fil et une station de base ; et, lorsque la performance de transmission du canal sans fil est bonne, à établir une connexion à grande vitesse entre la station de base et le terminal sans fil et, lorsque la performance de transmission du canal sans fil est médiocre, établir une connexion à faible vitesse entre la station de base et le terminal sans fil. La présente invention peut améliorer l'efficacité de transmission de données sans fil.
