There is something called Antenna Tilt, we can call it angle of antenna as well, and Antennas should have been optimised (directed) to the campus coz there are lots of students hanging round there. I think that's why....
better to go for QS coz even u can do something yours but with telecom it is realy difficult.
And now a days work in Telecom feild is very difficult NO day n Night coz, time = money
