We are optimizing Mobile WiMAX network.
Sites are mostly 600 meters away from each other and heights of sites are different in urban area its between 35 to 55 meters.we have only 3 channels and we have 3 sector per site. we are 65 degree beamwidth antenna....
on 50 meter height if we use 15 mechanical tilt its covering in horizontal direction and interfering with others sites near by and if electrical tilt is used only 10 degree it will lower the coverage and may be overshoot...
Please i need expert advice to tilt the antennas...
Can we use electrical + mechanical tilt(some professional said it is not advisable)...
The on sites which are higher what will be advisable....
Please if someone have documents regarding this....
