I already implemented 1*3 with 6 freq. For s4/4/4 tch drop increased then we decided to change reuse type to 1*1 with 18 freq. tch drop decreased with sdcch drop increasing by more than 5% per network; diffrent cells not whole, and GPRS service stopped on gsm that i worked on! Yes TBF download became 10%!! and started at the same of frequency plan implementation!
Question: Freq. Plan could be areason for above problems? Alcatel network,
