The method involves integrating two Ethernetdata frames e.g. profinet data frames, to Ethernettelegrams e.g. profinet telegrams, and transmitting the telegrams over a wireless communication network. The telegrams are compressed by removing padding bits from the data frames and/or from the individual telegram, and a medium access control header provided in the data frames is removed. The telegrams are transmitted by a Ethernetprotocol. Independent claims are also included for the following: (1) an ethernet receiving method for receiving ethernet telegram (2) an ethernet transmitting device comprising a transmitter (3) an ethernet receiving device comprising a receiver (4) a computer program for performing ethernet transmitting method and ethernet receiving method.
