[Tinyos-help] [Q] Interfame space(IFS) in CC2420 (telosb)

[ipark at ncsu.edu]

Hi,

According to IEEE802.15.4 spec, MAC sublayer needs a finite amount of time
(IFS) to process data received by PHY.
And aMinLIFSPeriod is defind 40 symbols period.
I can't find the IFS in spec. and MAC code of CC2420.
Is TX_TURNAROUND(12 symbols period) enough for the IFS?
I'm wondering if the IFS should be enough long to move first frame in
RXFIFO(CC2420) out to memory(msp430) and receive second frame, when one
telosb receives two frame continuously.
