Please see the CC2420 datasheet available at http://www.chipcon.com

Hello, I'm simulating WSN in OMNeT++ and I'm using as reference Tmotes parameters. I would like to have extra information about Tmotes behaviour, mainly about the Radio CC2420 which is not available in the datasheet. I need to know the times the chip requires to turn between different states, Idle to RX/TX & vice versa, RX to TX & vice versa. Also if a preamble is transmitted at the beginning of a Poll, how much time a Receiver will need to be aware of this transmission, i.e. if it was Idle and just turns on to RX, how long it will need to detect the preamble. That information will be required implementing protocols as WiseMAC where nodes, if not synchronized, transmit long preambles and receivers can remain their radios sleeping and detect this preamble "waking up" for a short time if at least they sense the channel every half of the preamble time; therefore saving energy. I would appreciate any link with regarded information.
