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 guys,
i am trying to modify the BlinkToRadio program to control the transmission
power.
I have modified the BlinkToRadio Makefile code to this :
OMPONENT=BlinkToRadioAppC
include $(MAKERULES)
PFLAGS+=-DCC2420_DEF_RFPOWER = 10;
Can somebody PLEASE tell me of i am doing this correctly if not
Hi All
I know we can set the transmission power levels of different motes. I want
to know what is the correlation factor between the transmission power level
and distance that it can reliably propagate ?
I am using MICAZ motes and MTS310 sensorboard.
Thanks

Hi all,
I would like to adjust the Transmission power of all sent packets. To do, I
added this line in the makefile: CFLAGS += -DCC2420_DEF_RFPower=3 (low
transmission power of CC2420 compatible platforms)
However, I think that this command didn't work as expected because links
connectivity stays
And i am using telosb motes...

Akankshu,
It really depends on a lot of factors. An environment with lots of
obstacles(trees, cubicles, buildings, cars, etc) can cause severe
multipath effects which make estimation difficult. But as a start, you
can look at free space propagation loss models. These will give you a

Thanks a lot Paul. That was really helpful and I now have a place to start.
I am implementing some routing ideas in an application similar to
SoundLocalize and needed for this.
Can you also guide me with ReadStream and MicStream interfaces which might
be more suited to my application since I need
Hi,
How did you justify the link quality? Which metrics did you used? Topology?

Hi,
I compute the BER based on packet reception ratio between two nodes.

Did you check that the sending mote actually transmitted at TX = 3? What's
the distance between them?

How can I check this?
The distance is about 2m + obstacles.

Have a look at the commands provided by the CC2420Packet interface. I think
you should have also measured the RSSI.

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 "whit
Ok
Thank you very much.

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
Hello all,
MICAz transmission power is 0 dBm. In addition MICAz can transmit power
values between 0 dBm to -25 dBm.
The question is how can I select the transmission power ?

Hi,
I'm a beginer with TinyOS and I would like to have a low radio
transmission power to test Collection without dispatching motes
(TelosB) in all the building...
So I found this thread

which speak about CC2420PacketC.nc
Hi all,
I have a question regarding the transmission power setting in TinyOS 2. It
seems that the using CC2420Packet interface, we can set transmission power
for each packet.
Now here comes the question. If we are using multihop forwarding, such as
CTPforwarding engine, do we need modify the forw

I want to ask how can I change the default transmission power of MICAz mote
(0 dBm) to other values such as -10 dBm or -15 dBm

within module implementation, to set transmission power for the packet is 0 to

Well, I wanted to set my RF power, based on my received signal strength,
so I would save a little of energy. But I am really confused on how to do
so.
First of all, I do not know the unit of some things. For example, how do I
interpret the strength_or_preamble field of a incoming packet? I realize

Hi,
You may use CC2420Packet interface (assuming you are using TinyOS 2.x ).
( tos/chips/CC2420/interfaces )
If I remember well, you should use the setPower command.
Good luck,

You can find all information you need in this file.

And yes, 0dbm is the maximum output power.
