Abstract

In an embodiment, a communication method, using OFDM (Orthogonal Frequency Division Multiplexing), comprises transmitting and receiving packets between a first node and at least one second node, where each packet comprises a preamble and payload data. The method, performed by the first node, may comprise receiving packets from the at least one second node, and authenticating the at least one second node based on physical layer characteristics, i.e., on CSI (Channel State Information). The authenticating may be based on a plurality of preambles, which are extracted from a group of consecutively received packets.
