said by Jafster:Thanks Lutful... The green colors are facing to each other you think it will work that way? i am assuming that the green color are on the same polarity and same freq.
Yes, same color means same channel and polarity. SM antennas are usually more directional and there is no problem even if beams of same frequency and polarity cross each other while going to different APs.
The only problem that can happen in TDMA systems is a very strong SM in one sector swamping a very weak SM beam in the directly opposite sector. Think about the short fat red arrow SM directly opposite one of the long thin red arrows on tower 2.
I drew some arrows to show how you could assign same SM to different APs in the various frequency zones. The general goal of frequency allocation and sector antenna orientation is to maximize SM-to-AP pairing options. You will notice that the green frequency zone is actually the largest and most flexible.
