Yes,it is vendor specific.Regarding Interference,no such impact will be there.
Thanks Pix
By default,both transmit at max power,for sure.But in some vendors,we can play more:-)
Regarding C/I degradation.the SACCH frames are filled with dummy burst during HO command,which causes a minor degradation in C/I & Rx_Qual.Since MS measures all the DL bursts,it is shown in TEMS.However,these measurements are excluded in BSC,so your BSC RX_Qual will not get impacted.
