thanks. actually the data content is not important for my project. the important criteria are (i) fixed txn duration (which can be upto 500 msec) (ii) a means to determine duration at Rx end (iii) duration is selectable and (iv) duration should be as precise as possible.
ur guidance is valuable. but i am not sure how the time of txn can be set precisely and what means I can have for determining the transmission duration at rx end. moreover which of the ics (cc1150 etc) will u sujjest to start with.
regards.
