Hi Is it possible to change the default transmission power in TOSSIM? It seems to be 0 dBm and cannot be changed. What exactly is link gain in TOSSIM? If the TX power is 0 dBm and link gain is -75 dB, can I say the received signal is -75 dBm? Thanks.___

Hi all tinyos users, I am pretty sure that adding -DCC2420_DEF_RFPower=3 in the makefile doesn't really adjust the tx power to the minimum. Sending packet with such tx power should be (and only by this way) in the code as follows: call CC2420Packet.setPower(msg, 3); Best regards, Alfred Nooobel

Alfred, It really depends on what your topology looks like. If the nodes, before the change, received messages with an RSS of -45 dBm, and you reduced the power level from +0dBm to -15dBm. The RSS would go from -45dBm to -60dBm. Depending on your hardware, this can still be within the
