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<a predetermined maximum npdb value, a first CCA is performed on the radio device's receive (Rx) channel, and a value for npdb is incremented following a failure. A second CCA is performed on a target radio device's Rx channel, wherein a value for nb is incremented following a failure. Provided a not busy is determined in the second CCA the radio device transmits a frame on the target radio device's Rx channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel hopping aware channel access and re-transmission","description":"A method of channel access for a radio device in an asynchronous channel hopping wireless network.
