Reply To: Interference on Idle TCH


What is the cause of interference on dedicate mode?

I experienced an issue during refarming on BCCH. We were on for example 68-92. Then we had to use 48-66. After the change few cells could not pick up its neighboring cells on the range from 48-66 has planned but picked up the ARFCN frequency range from 68-92.

What could be the possible cause of these?
I use both nortel and huawei systems and the issue is with the Huawei BTS not able to handover to nortel bts in the ARFCN range from 48-66 but instead picking up the 68-92 frequency range. All parameters have been checked but issue still exists.
