A method for data transmission in wireless local area networks in which data transmission is implemented between a first and a second communicant, and in which a first standardized data transmission rule is implemented requiring transmission and/or reception of information elements with variant element formats on electromagnetic signal paths, with the information elements comprising an element identification part, a length statement part and an information part, and the element identification part having a permissible value range in which a first standardized value of the element identification part identifies the information element as a first information element whose information part contains parameters which relate to the data transmission of the communicant in accordance with a first data transmission rule as the transmitter, a receiving communicant storing the parameters for the transmitting communicant in order to set the data transmission for return to the transmitting communicant, and each of the communicants, as the receiver determining the length of the information part from the length statement part on identification of a value of the element identification part outside the permissible value range, and jumping over the information part corresponding to the determined length, the method comprising the step of:
- at least in the case of one of the communicants, implementing in addition to the first data transmission rule a second data transmission rule expanding the permissible value range so that a second standardized value of the element identification part identifies the information element as a second information element whose information part contains parameters which relate to the data transmission of the transmitting communicant in accordance with the second data transmission rule.
