Figure Q$2$

User A$,$ user B$,$ and user C are currently associated with the lower$-$left base

station $($BS$3).$ The locations of these users are marked by the circles in the figure

above. The distance from each user to the associated BS is $R.$ Assume a path loss

exponent of $n=4.$ Do not approximate distance values.

$($i$)$ Find the signal$-$to$-$interference ratio $($in $dB)$ for user $A.$

$($ii$)$ Find the signal$-$to$-$interference ratio $($in $dB)$ for user $B.$

$($iii$)$ Find the signal$-$to$-$interference ratio $($in $dB)$ for user $C.$
