WIRELESS COMMUNICATION

LINK BUDGET 1
Answer-1
The facts given in the question shows that the values of distances are 5KM and 10KM and two various
frequencies are 5.8 GHz and 2.4GHz. Below mention equation and provided data can help for
determining the total free space path loss.
Here d is distance and f is the frequency of the signals which are already given in the question. Now just
put d= 5KM and 10KM and f= 2.4GHz and 5.8GHz.
Therefore, the values of free space path loss at different-different values of distances and frequencies
are indicated in the below table:
FS
PL(dB)
Distance (KM) 2.4GHz 5.8GHz
5 114.03 121.70
10 120.05 127.72
Answer-2
In the given case study there are numbers of parameters mentioned which are used for determining the
link budget and link margin in the wireless networks. The below-mentioned formulas can help in solving
this question:
It is given both transmitter and receiver antennas are the same so the total gain is around 48dB.
Therefore, the total path loss is given as
