Dear All,
we have deployed the WiMAX TDD Network using FRP3 having three frequency channel of 10MHZ on 2.5 GHz...
Even we have 3 frequency channels but still we are getting co-channel interference because site are maximum 600 meters from each other, i have tried my best that sectors sharing the same frequency channel are not directly facing each other but still we are getting low values of CINR sometime sector which very far covering the area with bad CINR values....some sites are having height 50 meters and some are 25 meters....currently we didnt have any attenuation on the sectors configured...main thing antenna have only mechanical tilt....electrical tilt is not supported....according to my knowledge we can play only with attenuation but how...or anything else we can do for it....
Please help me by providing your professional guidance on this,,,,,,,,
