Welcome to your question.
00:03
We have a certain city that is having area of so the city is having the area that is 1 ,300 square miles and we have the cell radius so that is 4 miles is given and we have the cellular system is 7 cellular system.
00:31
So here we have the frequency reuse factor frequency reuse factor is given so that is equal to 7 and we have here the value of so these are the values that are given and we have all four miles the city is allocated with 40 miles of the 40.
01:03
M mega hedges of spectrum with full duplex channel bandwidth so we have bend width is given so channel width is channel width is equal to 60 mega sorry kilo hedges and we have the channel allocated spectrum so here it is allocated spectrum is given is equal to 40 mega hedges is given so here some questions are given so geo is also given for this one 2 % and the traffic per user is given so traffic per user is 0 .03 allance so now we have to calculate the first thing is number of cells in the service area number of cells in the service area is equal to so here we have the number of cells in a service area is equal to area divided by the cell area of the cell so area of the city divided by area of cell.
02:51
So as it is a hexagon cell, we will have the area of cell.
02:57
Area of cell is equal to 6 multiplied by half.
03:04
It is multiplied by r.
03:06
It is multiplied by 3 root 3 divided by 2r.
03:11
So here the value of this one will become, so 2 .981...
