Adaptive Access SchemeShiron's InterSKY system offers the Adaptive Access Scheme utilizing patented

Dynamic BM-FDMA technology. InterSKY's Access Scheme provides the superior

combination ofBoD + Clear Channel/Managed SCPC + Dynamic Random Access

modes.

In contrast to MF-TDMA based systems, InterSKY Adaptive Access Schemes

automatically maintain optimal satellite resources, while managing service

availability.

MCD combined with BoD (Bandwidth of Demand), TRC (Traffic Rate Control) and

APC (Automatic Power Control) allows an ACM (Adaptive Coding and Modulation)

operation in inbound direction with a large dynamic range that can combat large rain

fade and maintain the link connectivity with high availability.

Inbound ACM includes the following major components:

MODCOD selection (QPSK, 3/4; 8PSK, 2/3 ; 8PSK, 8/9)

Dynamic APC and BoD

Dynamic TRC

16APSK Over Satellite Multicarrier Case

InterSKY system enables to use more PEB (Power equivalent BW) thanBW for 16APSK Outbound carrier by balancing with inbound channels.

Multicarrier operation uses linear mode and as result no distortion foramplitude modulation of 16APSK

Embedded equalizer in the modulator compensates for group delay andamplitude variations.

InterSKY system allows to work on the edges of transponder bymanagement of satellite resources allocations - inbound on the edges andDVB-S2 carrier on the center of transponder

Best Outbound Solution in the Industry


15/32


16APSK Over Satellite Saturated Transponder Case

InterSKY system allows to work with saturated transponder using :

Embedded equalizer in the modulator

Back-off according to the DVB-S2 standard

Taking into account the degradation

"ETSI TR 102 376 V1.1.1 (2005-02) Technical Report" in case of 16APSK

and with dynamic predistortion the expected degradation is 1.5 dB and therequired backoff is IBO = 1.0 dB ; OBO = 1.1 dB

Best Outbound Solution in the Industry


16/32


Bidirectional ACM Technology

InterSKY solution allows significant enhancement the advantages of DVB-S2

standard using advanced bidirectional ACM technology (patent-pending).

Designed to manage service delivery with highest availability and minimum

satellite resources this technology delivers combined & embedded capabilities:

Advanced bi-directional ACM

AUPC Switched beam operation

Multisatellite centralized ACM operation

Ability to operate with full saturated transponder and on the transponder

edge

Designed for simplicity of network implementation and operation


17/32


Advanced ACM Management

Advanced ACM technology from Shiron achieves the highest totalthroughput through dynamic selection per VSAT of the best

combination of coding and modulation according to coverage gain andclimate conditions while managing satellite resources (power &bandwidth) in the most efficient manner.

The ACM controller collects desired information and considers theoptimization modes in several dimensions:

Bi-directional (outbound & inbound) optimization of MODCODsper VSAT

Total satellite resources utilization with optimal power vs.bandwidth balancing for combination of the following parameters:

DVB-S2 transponders saturation

Between outbound and inbound carriers in non-saturatedtransponders

Between multiple inbound carriers

SHIRON SOLUTION16APSK Outbound 8PSK Inbound and ACM

.- What mean Highest MODCOD Availability ?Is the % of time which the Outbound will be operating with the highest MODCOD. For this case, the

Outbound will operate under 16APSK FEC 0.8 in 92% of the time.

.- What mean Required MODCOD Availability ?

Is the MODCOD use to guarantee the availability required to the network: 99%. For this case, the

Outbound will operate under 8PSK FEC 0.8333 with bad climate condition, worst case.

.- How long time the Outbound will operate in Highest MODCOD and in Required MODCOD ?To this case Highest MODCOD: 92% of the time.

To this case Required MODCOD: 99%-92% = 7% of the time.

.- What about the Inbound ?The analysis is similar but the Highest MODCOD supported is 8PSK FEC 0.833.

.- What about the satellites Power and BW resources use ?

Like 16APSK use less BW but more power resources from the satellite. The systems is designed to do

the balance Power Vs BW between the Outbound and Inbound. The total power and BW used is

balance.
