6. 6
• Modular design approach
• Each Millennium rack can be customized to meet specific
customer requirements
• FL or RL equipment blocks can be added as the network
capacity expansion dictates
• In RL Block, MCD or RL processors cards can be added as
network capacity expands
• Various redundancy schemes are available from 1:1 to 5:1
• Additional racks can be added as network expands

9. 9
Today’s Technology for Forward Link
• Outbound or FL from Hub is based on DVB-S2 standard
• DVB-S2 Technical Module (TM) has been developing a more efficient use of the
satellite bandwidth
• DVB-S2 TM has developed together with the academia and equipment
manufacturers an extension to the DVB-S2 standard
• A major goal was to improve the throughput of the satellite transponder
• An extension to the DVB-S2 standard was approved in March 2014 generally
called DVB-S2X

10. 10
DVB-S2X Enhancements
This standard provides improvement in the DVB-S2 standard
• Reduces minimum rolloff from 20% to 5%
• Granularity increase – more modcods
- Provides finer resolution on modcod selection
• Introduces new modulation - 64APSK
- Gives 6 bits/symbol instead of 5. Provides 20% improvement in throughput
• Concept of time slicing
These enhancements enable to increase the throughput on the FL of up
to 30%
• However, the power required to transmit these signals is increased by 100% due to 0.2
to 0.05 rolloff factor and the change from 16/32APSK to 64APSK

13. 13
Time Slicing Approach
• Spot beam transponders (up to 500 MHz) are virtually divided into Time
Slices
• This concept has been used for years in cellular networks
• Each time slice represents a portion of the total bandwidth of 500 MHz
• Each ISP/User demodulates only their “Time Slice” of a complete carrier
• Each Service Provider can buy a portion of the total Carrier in
Msymbols/s
• Can support many Service Providers and still use single carrier in
transponder yielding significant increase in throughput
