UAT Schedule adjustment• All sites are affected due to this change.• SFC needs some measurement before parameter
change,so that all SFC carrier will stop 1 day.
• Basic policy– Ku-Band and C-Band UAT goes independently.– Both C and Ku band changes takes a day.– When stopping the carrier and UAT , please call to YSCC.
• I will prepare the table including frequency, symbol rate and carrier type information, then I will send the web location of it to you using “[email protected]”.
