Wireless preamble design

A method includes building a wireless packet that includes a preamble that is compliant with a first wireless communication protocol and is forward compatible with a second wireless communication protocol that is different than the first wireless communication protocol. Building the wireless packet includes building the preamble with a first subset of bits that are specified in both the first wireless communication protocol and the second wireless communication protocol, the first subset of bits including one or more media access control (MAC) layer characteristics. Building the wireless packet includes building the preamble with a second subset of bits that are specified in the first wireless communication protocol exclusive of the second wireless communication protocol. The method further includes transmitting the wireless packet to one or more receiver nodes.

METHOD FOR DETECTING SYSTEMATIC COMMUNICATIONS IN A COMMUNICATIONS NETWORK, CORRESPONDING DEVICE, AND COMPUTER PROGRAM PRODUCT

Described herein is a method for detecting systematic communications in a communications network (10, 30). The method comprises repeating the following steps for each data packet (DP) of a sequence of a plurality of data packets (DP) sent through the communication network (10, 30) from a respective source to a respective destination:

obtaining (1002, 1004) metadata (MD) of the data packet (DP), wherein the metadata (MD) include both data that identify the source and/or the destination and data that identify a sending time (t) when the data packet (DP) has been sent;

verifying (1022) whether the data packet (DP) belongs to a specific type of communication by checking whether the metadata (MD) indicate the fact that the data packet (DP) has been sent by a given source and/or received by a given destination, and in the case where the metadata (MD) indicate that the data packet (DP) has been sent by a given source and/or is received by a given destination, computing (1024) a value of variance for the given type of communication; and

comparing (1012) the value of variance with a threshold (TH), and in the case where the value of variance is less than the threshold, generating (1014) a notification that indicates the fact that the given type of communication is systematic.

In particular, the value of variance is calculated by means of an iterative procedure.
