Abstract: A method of channel access for a radio device in an asynchronous channel hopping wireless network. A backoff time is set from an Interference Avoidance Delay plus a random backoff time for transmissions from the radio device. For initial frame transmissions, an initial value for a number of backoffs (nb) and initial number of preamble detection backoffs (npdb) is set. After waiting for expiring of the initial backoff time and provided a current npdb_value
