Question

please Teacher help me with this question step by step please and explain everything my Teacher?

1. What is the channel frequency? To find the frequency, expand the Radiotap header of any frame and look for the Channel frequency.

2. What rates are used? Give an ordered list of rates from lowest to highest. Hint: you can click the Rate column to sort by that value.

3. What is the range of RSSI and hence variation in SNRs in the trace? Give this as the strongest and weakest RSSI and the dB difference between them.

4. What is the BSS ID used by the most active wireless conversations? A BSS ID value identifies an AP, so this BSS ID identifies the most active AP, presumably the AP we are monitoring. To help find it, you can sort on the source or destination address by clicking on the column heading

Answer 1

1. Expand the Radiotap header of any frame and look for the Channel frequency thus, The Channel frequency is 2462 MHz, or 2.462 GHz. It is known as "802.11b/g channel 11"
2. The rates from lowest to highest are 1, 6, 12, 18, 24, 38, 48, and 54 Mbps.
3. The RSSIs range from -44 dBm to -69 dBm. This is a variation of 25dB or around a factor of 300 in the SNR. The strongest RSSI is -44 dBm and weakest is -69dBm
4. The BSS ID used by the most active wireless conversations is 00:16:b6:e3:e9:8f.

Thank You !
