A wireless communication management method between a base station and at least one wireless device, said method comprising: • the base station broadcasting presumably free and usable channels, creating, by means of the base station, a list of k free channels within a range of time intervals for a wireless connection with said base station, where said list comprises at least a slot number for each channel; and • the base station periodically broadcasting said list; the method being characterised in that it comprises the following steps: • i) listening, by means of the wireless device, the list of k channels broadcasted by the base station for accessing within a certain time interval; • ii) creating, by means of the wireless device, a group of n channels randomly selected from among the channels comprised within the list of k channels, being n comprised between 1 and k; • iii) randomly ordering, if n is greater than 1, said group of n channels by means of the wireless device; • iv) selecting, by means of the wireless device, at least one candidate connection channel positioned in first place in the group of n channels; • v) determining, by means of the wireless device, that the candidate connection channel selected in the preceding step is in radio silence mode by listening on said channel in at least one frame interval, in at least one direction during the time comprised between the broadcast of available channels emitted by the base and the access instant to which the channel broadcast refers; and • vi) when it is determined that the candidate connection channel is in radio silence mode; establishing access between the wireless device and the base station by means of a bearer using the selected candidate connection channel, • vii) when it is determined that the candidate connection channel is not in radio silence mode, repeating the steps i to v starting with the observation of a new broadcast of channel information emitted by the base station and repeating the random selection by the wireless device of at least one target channel based on this new information until a candidate connection channel in radio silence mode is found, • viii) analysing, by means of the wireless device, a response emitted by the base station to the attempt to establish connection, or absence thereof, • ix) determining the connection as successful when the response emitted by the base station to the attempt to establish connection, comprises a successful connection message, and • x) executing a collision management process that comprises the establishment of a standby time that can be measured in either frames or in slots and that has a random component, when the response emitted by the base station does not comprise a successful connection message. • the base station broadcasting presumably free and usable channels, creating, by means of the base station, a list of k free channels within a range of time intervals for a wireless connection with said base station, where said list comprises at least a slot number for each channel;
