Hi All,
as reported in the EMANE manual, one packet is received or discarded with
Probability of Reception (POR) based on the following relations:
SINR= rxPower - rxSenstivity
where:
rxPower = txPower + txAntennaGain + rxAntennaGain - pathloss
rxSensitivity = -174 + NF + 10 log10(bandwidth)
In the case I'm using freespace or 2ray models in EMANE which is the value of
pathloss?
For instance:
SINR and POR are defined in ieee80211pcr.xml.
If I have an unicast rate equal to 24Mbps = index 9 I'm interested to the
following section in the xml:
<datarate index="9" rate="24Mbps">
<row sinr="9.0" por="0.0"/>
<row sinr="10.0" por="2.2"/>
<row sinr="11.0" por="23.8"/>
<row sinr="12.0" por="64.4"/>
<row sinr="13.0" por="90.4"/>
<row sinr="14.0" por="98.4"/>
<row sinr="15.0" por="99.8"/>
<row sinr="16.0" por="100.0"/>
</datarate>
That means that from my previous formulas SINR should be compared to the values
in XML.
Is that right?
Last question, the value of POR in XML is POR or POR0 from the following
formula:
POR=POR0^(S1/S0)
where S1packet size received (e.g. 1400 bit) and S0 = 128 defined in the XML.
Is that right?
Thanks in advance for your answers.
Best Regards,
Simone
