WiMAX Interference - Ant Beamwidth

[MyVi78]

Fellow members,

If there's anyone of you involved in WiMAX, may I know what are the Ant beamwidths being used in your operators' network?

ALU for example deployed 120 Deg, which is giving me a huge headache due to sidelobe interference.

Would appreciate your feedbacks.

Hello,

we're using 90deg antennas
what permutation scheme and frequency reuse on your network?

we are using also 90 degrees antennas, but we also faced some internal interferenece issues which causes no network entry...and solved by change frequencies

Experience in using 65 deg before. 3 sectors, each 10MHz.
Some location are even interfere by other operators which the split over of the side lobe which not cut off sharply. No guard band between the operators.

4sectors x 90° and 3 sectors x 60°, you can experience problems when tilt is too high, should be interesting compare different antenna patterns on a RF simulation tool.
