Method and device for transporting Ethernet data packets via radio frames

In order to transmit Ethernet data packets via radio frames (350) in a wireless communication network, terminals (100, 100 ') are used with a receiver to receive the data packets via a communication path (102). The data packets do not all have the same length. Furthermore, a formatting device (228) for formatting is used to fit the radio frames., (3.50), Jdef these, all have the same length. The formatting is done so that the boundaries of the packages are not necessarily going to escape ...... ________________________ ..

with radio border boundaries. For transmission via the communication path (102), a transmitter / receiver is used in the form of a microwave module (246). The Ethernet data packets may be in the Fast Ethernet category.

In the terminals (100, 100 '), the packets are not converted using known transmission protocols (e.g., ATM) before the transmission of the radio frames via the communication path (102). The terminals may have a synchronization step (256) for synchronization with a clock signal assigned to the radio frames (350).

The data packets can be — time multiplexed before the radio frame adaptation.

The data packets may have a front portion and a frame start boundary, and their transmission via the radio frames (350) may involve removal thereof.
