Abstract: Where each node device is assumed to know the time-of-day with an accuracy of only plus or minus 1 second, the geolocation of said node device is determined by an A-GNSS server by help of a time-stamp known with an accuracy better than or equal to 10 milliseconds and added by at least one transceiver of the asynchronous RF network. Indeed, the technical feature of said asynchronous RF network according to which the time-of-day at which data are sent from each node device is known in a deterministic manner allows the A-GNSS server to determine retrospectively this time-of-day in function and with the precision of the time-stamp added by said at least one transceiver to the data packet issued from said node device over the asynchronous RF network.

Abstract: The disclosure relates to transmitting a sequence of sets of data, from a communication device to an access point of a wireless communication network, through at least one radio communication channel to improve radio communication quality to cope with environmental condition changes and/or location changes of the communication device and/or changes of usage of the communication device in terms of mobility. For each set of data, a value of at least one parameter to be used by the communication device for transmission is determined by selecting, in a list of predetermined values of parameters, a corresponding value. The number of occurrences of each predetermined value is determined according to a probability that the selection leads to a transmission of data with at least one quality criteria fulfilling at least one predefined condition. Each set of data is then transmitted according to the value of said at least one parameter.
