  28. New AI3 C-Band Frequency Allocation 18MHz • When more than 3 197KG7W carriers are transmitted from SFC, the SFC license need to be changed. -18 -17 -16 -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 394KG7W (512kbps) VN ↓ SFC 394KG7W (512kbps) SG ↓ SFC 394KG7W (512kbps) MY ↓ SFC 394KG7W (512kbps) PH ↓ SFC 197KG7W (128kbps) Laos ↓ SFC SFC transmit VN transmit PH transmit SG transmit 9M40G7W (9690kbps) SFC ↓ UDL 197KG7W (128kbps) SFC ↓ Laos 1M19G7W (1536kbps) SFC ↓ VN 1M19G7W (1536kbps) SFC ↓ MY 1M19G7W (1536kbps) SFC ↓ SG 1M19G7W (1536kbps) SFC ↓ PH MY transmit Laos transmit

  29. 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 “ai3-ix@ai3.net”.

  30. Ku-Band UAT Time Schedule • Related Site • NAIST, ITB, AIT • Procedure Outline • AIT -> NAIST and NAIST->AIT changes • ITB -> NAIST and NAIST receive change in parallel. • Let’s fix the changing date (10/10) • 10/10 11:00~13:00 JST (9:00~11:00 @AIT) • AIT will stop and start to transmit after parameter change. • NAIST will confirm the receiving carriers. • NAIST will stop and start to transmit after parameter change. • AIT will confirm the receiving carriers. • 10/10 16:00~18:00 JST (14:00~16:00@ITB) • ITB will stop and start to transmit after parameter change. • NAIST will confirm the receiving carriers.

  31. C-Band UAT Time Schedule • Related Site • SFC , PH , Laos , All UDL RO site , MY , VN , SG • Procedure Outline • PH->SFC,SFC->PH and Laos->SFC, SFC->Laos change. (Step-1) • All SFC carriers stop and do some measurement. (Step-2) • All SFC carriers start to transmit after parameter changes. (Step-3) • Let’s fix the SFC measurement date (11/14) • 11/14 10:00~12:00 JST (8:00~10:00@Laos ; 9:00~11:00@PH) • PH->SFC and Laos->SFC will stop and start to transmit after parameters change. • SFC confirm the receiving carriers. • SFC->PH and SFC->Laos will stop and start to transmit after parameters change. • PH, Laos will confirm the receiving carriers. • 11/14 13:00~17:00 JST (11:00~15:00@Laos,VN ; 12:00~16:00@SG,MY,PH) • SFC will stop all carriers, and do some measurement and transmit carriers after parameter change. • 11/14 18:00~ JST (16:00~@Laos,VN ; 17:00~@SG,MY,PH) PH,Laos, MY, VN, SG, all RO site will confirm the receiving SFC carriers.
