Abstract
(EN) The present invention relates to a method for configuring a physical layer of a low frequency band based on wireless magnetic field communication, and a computer-readable recording medium including a program for executing the method. The method supports the proper packet format, coding mode, and modulation mode between a master and a slave in order to enable wireless communication in variable data rate or coding modes depending on a peripheral environment in a low frequency band based on wireless magnetic field communication which is applied to a difficult environment. The method of the invention is characterized by changing the data rate and the coding mode of a payload field within a preset range depending on the peripheral communication environment, wherein the payload field is included in the request and response frames between the master and the slave. The request and response frames can be configured in the same format in the above-mentioned configuration and respectively include a preamble field, a header field, and the payload field.
(FR) La présente invention concerne un procédé de configuration d'une couche physique de bande basse fréquence sur la base d'une communication sans fil par champ magnétique, ainsi qu'un support d'enregistrement lisible par ordinateur comprenant un programme destiné à exécuter le procédé. Le procédé prend en charge le format de paquets, le mode de codage et le mode de modulation entre maître et esclave convenant pour permettre une communication sans fil en faisant varier le débit de données ou les modes de codage en fonction d'un environnement périphérique dans une bande basse fréquence sur la base d'une communication sans fil par champ magnétique appliquée à un environnement difficile. Le procédé selon l'invention est caractérisé en ce que l'on modifie le débit de données et le mode de codage d'un champ de charge utile dans les limites d'une plage prédéfinie en fonction de l'environnement périphérique de communication, le champ de charge utile étant inclus dans les trames de demande et de réponse entre maître et esclave. Les trames de demande et de réponse peuvent être configurées selon le même format dans la configuration susmentionnée et comprennent respectivement un champ de préambule, un champ d'en-tête et le champ de charge utile.
