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

● 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..

3-Play and Ku/Ka solution
● Cost effective integrated solution for
Interactive IP and DTH
● VSAT and DTH may be on same satellite or
different satellite (e.g. 4 or 8 degrees apart)
● Dual feed structure (BUC and LNBs) is pre-
assembled to guarantee accuracy
● Gilat brings experience in developing Ku, Ka
and hybrid Ka/Ku products
● Solution can begin with Ku band service and
upgrade to Ka band - same IDU and antenna
Ku/Ka product
Dual VSAT/DTH feed patent was awarded to Gilat
