hi all.
I'm a student and I'm working on WSN with telosb motes and I'm using TinyOs
2.x.
Telosb motes uses cc2420 Radio Stack , so i want to exstimate the maximum
transmission time for a packet of 28 bytes ( max payload lenght)
i think that the total transmission time depends on:
time to transmit

isn't one jiffy 32us? if so, the ack wait time should be 8.192ms.

i have a question. Why do CC2420 need to wait for hardware ACK for such a
log time? It should be very fast.

I think it's mainly due to software-ACK and the congestion backoff mentioned
by Phil.
