Thanks for your quick answer. Well we are going to use low gain antennas with a Vertical of 55 and 28 degrees. Also what I am thiking of is a great tilt may cause a wider cell which may increase the overlap between the other neighbouring cells. By the way I am using MacroBTSs with a PA output power of 40W for microcells so I think reducing the power might be a good idea. What do you think pix?
