  3. 3. Confidential and proprietary information Ka-Band and Application Use ● Ka-band technology can be used for almost any application ● Internet Access & Corp applications ● Disaster recovery and Emergency response ● Video contribution (DSNG) ● Local video services ● Some limitations of Ka-band ● Multicast services – limited to spot beam coverage area ● Mobility – need handover between beams ● High throughput Voice trunking ● Primarily due to the high raid fade swings 3
  4. 4. Confidential and proprietary information Market view International connectivity Enterprise & Gov’t projects Internet connectivity C- Band Ku- Band Ka- Band The market as a whole will benefit! 4
  5. 5. Confidential and proprietary information 5 ● It is a unique application and specific implementation per satellite and per network ● Wideband (>72Mhz) beams ● High throughput hubs/multiple NS ● NMS (Manager of managers) -> High variety between projects! ● The link ‘physics’ is challenging – with deep and rapid fades ● Support faster power loop, dynamic range, Gateway/RFT diversity, etc.. ● Actually, even the frequency band in Ka is not fixed –> requires special BUC designs ● There are many project considerations that need to be addressed - gateway locations, OSS/BSS Ka – it’s not just another frequency band.. Confidential - under NDA For representation only Gateways locations 03b Networks World Zones
  6. 6. Confidential and proprietary information Ka Projects in Gilat
