I am looking for transmit power typical value to be used in MANETs simulation. Any help?

Are you using ns2? If you do so, here are typical values:

# Initialize the SharedMedia interface with parameters to make

# it work like the 914MHz Lucent WaveLAN DSSS radio interface

Phy/WirelessPhy set CPThresh_ 10.0

Phy/WirelessPhy set CSThresh_ 1.559e-11

Phy/WirelessPhy set RXThresh_ 3.652e-10

Phy/WirelessPhy set Rb_ 2*1e6

Phy/WirelessPhy set Pt_ 0.28183815

#Phy/WirelessPhy set Pt_ 0.00183815

Phy/WirelessPhy set freq_ 914e+6

Phy/WirelessPhy set L_ 1.0

Greetings,

karsten gänger.

Hi,

Do NOT use those default values from NS2. Nobody uses any 802.11 cards
with a 914MHz frequency. I don't think you can even buy them anymore.
Maybe. But you wouldn't be able to use them in Europe, where 900 Mhz is
NOT an ISM band.
I suggest looking at a datasheet or the specs for some popular card. For
example:

Anders

Hi Anders,

yes, you are write, simulations with 2,4GHz are much better. But ns2
just uses free space propagation, so it is most important to keep the
transmission distance at about 200m-250m.

I would like to uses also the 'correct' values for the ISM 2,4GHz band.
Which parameters do you use?

karsten gänger.
