Interference caused by ducting phenomena
Interference caused by ducting phenomena
(OP)
Hi all,
I am working on studying ducting effect on cellular systems in EGSM and how to reduce the interference caused by ducting
can anyone helps me with useful links or informations about the height above the sea level where ducting occurs or any other details
thanks in advance

RE: Interference caused by ducting phenomena
but i want to know if i will design Base station in area which suffers interference from ducting what is the best height for this BS to reduce this interference ?
and i read that ducting begin from 10-15 meters above the Mediterranean but i'm not sure from this info. so do you know if this is right or not
thanks in advance :)
RE: Interference caused by ducting phenomena
If you have a theory that the ducting can be avoided by having a tower of a certain optimal height, then (as far as I know) that theory is not correct (except perhaps in some limited cases).
On the other hand: If your base station is adjacent to the Mediterranean, the ducting interference is arriving from the sea, and your primary customers are on shore, then aim an antenna system null towards the sea. Easy.

i don't know what's your opinion ?

Obviously a shorter tower is going to be 'disadvantaged' for *all* distant signals, including ducting. Also, the resultant cell size (service area) would be smaller (you'll need more towers), and thus the clients would have to be closer, and thus their signals would perhaps tend to be stronger, and thus they would tend to out-gun the distant signal carried by ducting. Carried to extreme, if you bury your base station in the basement, it would be highly resistant to interference from ducted signals. It's not an interesting relationship, but it may be useful.
