6. Television is the biggest application in the world of
telecommunication satellites
7. Fiber cost is 10-20 times higher for
the last 10-20% of population

8. The Comsats Business is Changing
and Changing Fast!
Demand is growing all over the world
Useful Frequencies are scarce
Find new ways to deliver the capacity to the customers
Ka-band brings huge capacity
Small footprint beams are multiplied to cover large areas
accompanied by very large transmission power
9. New Type of Satellites are
emerging
And they are BIG
11. HTS – High Throughput Satellites
A traditional broad footprint
Optimised for broadcasting Optimised for IP applications
A signal received Multiple spot-beam
simultaneously by an architecture, allowing for high
unlimited amount of users frequencies to be re-used in
over a widespread area, order to generate a
covering at least a continent considerable increase in
bandwidth

13. 30 million households in Europe have less than 2 Mbps broadband
13 million with dial-up Internet access
14. Capacity For HTS is More Than Ten- Fold
A Game Changer ?
35 x more capacity than traditional satellites
KA-SAT, THE ‘80 GB/S GORILLA’
THE BIGGEST HTS IN THE SKY TODAY

19. Summary
Communication satellite are the backbone of the global
television distribution with an annual growth of more than 5%
Broadband (High rate internet stream) has a lot of geographical
limitations and does not reach most of humanity
No more available frequencies together with beneficial
characteristics of the Ka-band gives the business a new
approach for broadband delivery
Traditional wide-beam satellite and HTS multi-spotbeams are
complementary: two models for two types of applications

קבלת פרופורציות: רוב העולם צורך את התקשורת שלו דרך סיבים אופטיים: הן אינטרנט והן טלוויזיה (מבחינת נפח הם המשמעותיים)
communication satellite business is a niche in the world communications businesscomplements the global fiber optic networkIt is best used to distribute television but is rarely used for internet
Demand is growing all over the worldUseful Frequencies are scarce – especially in C and Ku-bandSatellite operators must find new ways to deliver the new required capacity to the customersKa-band brings with it huge capacity in comparison to traditional Ku and C-bands. The small footprint beams can be multiplied to cover large areas and is accompanied by very large transmission power
the HTS satellite – multi-beam in ka delivering Internet to fiber-less territories, trunking large portions of the internet through space and back to the ground
Bandwidth ratio between forward and return is highly dependent on the e-service considered
