You send preamble only when you have packets to send. So, if you don't have any packets to send, you will occupy 0% of the channel. If you have enough data to send then, sure, you can exceed 10% depending on how much data you have. - om_p _______________________________________________ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
