I want to ask the people optimizing 2G networks. What is the maximum deviation(in degrees +/-) of the planned antenna azimuth and the real installed, not affecting site performance? The site is 3 sectors 900mhz in rural area.

Thanks in advance

-/+ 2 degree would not affect site performance....Speaking from a drive testers point of view:D

i agree with RF engineer, any way for what purpose, and dont forget to check network utilization area.

can anybody explain the signalling process in handover from 3G to 2G ?

Thank you for the quick answers.

I think it is not related to the issue of my question. You can ask it in another thread.

the maximum is 13 degree, down tilt, include electrical and mechanical tile

-/+ 10 degrees. I agree with RF ENgineer.Based on experience also.

@ Processor : I agree with Mr./Mrs RF engineer's opinion. + / - 10 degree of azimuth is okey.
but your idea is for tilt, + / - 2 degree of downtilt is not much affacted to cell performance

:p oops...my apology to everyone as i actually thot he was asking for tilt...I totally agree with RF engineer for azimuth.

sorry i goofed:D
