pathloss is computed using the appropriate formulas for freespace (frequency and distance based) or 2ray (frequency and antenna height based).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?
Yes
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?
Yes
Thanks in advance for your answers. Best Regards, Simone _______________________________________________ core-users mailing list [email protected] http://pf.itd.nrl.navy.mil/mailman/listinfo/core-users
