IPSKY, Satileon's two-way broadband satellite communications system provides fast and efficient Internet, Interactive Multimedia and wide-ranging IP applications. Innovative and cost-effective, IPSKY brings high-quality broadband IP access to even the remotest locations.

Providing transparent IP connectivity, IPSKY allows service providers and enterprises to connect customers - businesses, remote offices, rural tele-centers, regional ISP's, schools and government institutions - to all facets of the IP network. The system brings the Internet and the 'triple play' services of voice, data and video to customers anywhere - even in regions that have no terrestrial infrastructure. And by bypassing terrestrial communication bottlenecks, IPSKY operates at unprecedented speeds.

No fair-weather friend, IPSKY delivers high-quality connectivity in all climatic conditions. Rainproof, the system equips service providers in the rainiest regions to offer access without additional equipment, power or bandwidth. IPSKY enables multiple users to enjoy multimedia applications at high speeds.

A single IPSKY platform can support hundreds of groups - containing thousands of customers - over numerous transponders and satellites.

The IPSKY system supports optimized real-world applications with low latency and lack of jitter. Providing end-users and services providers with fast and reliable solutions, IPSKY is ideally suited to the growing interactive broadband satellite market.

Satileon's field-proven Bandwidth on Demand (BOD) technology, based on IPSKY's BM-FDMA (Burst-Mode/Frequency-Division-Multiple-Access) feature, provides 30%-50% greater space segment efficiency, along with high-quality connectivity.

IPSKY boasts more bits per Hertz than any other system on the market with 8PSK turbo in both Inbound and Outbound. This means better broadband satellite connectivity at 30%-50% less bandwidth than with competing technologies. Experience proves: in broadband satellite communications, deployment bandwidth costs over time (OPEX) can be three to five times higher than equipment costs (CAPEX).

The scalable IPSKY system can grow along with your business. Start small and upgrade,in both size and capabilities to meet your changing needs. IPSKY's scalability allows service providers to hand-tailor systems to individual budgets and demands. With IPSKY, you can start from a few remote gateways with dedicated links and expand to thousands of terminals, combining both dedicated and shared bandwidth user groups.

Together, high-quality service, traffic shaping and jitter-free BM-FDMA technology, IPSKY's is optimized for real-time applications. Uniquely, these features offer bandwidth-sharing, without sacrificing link stability. Unlike TDMA, Satileon's BM-FDMA is based on bandwidth processing. This generates dedicated carriers of varying sizes on-the-fly, establishing temporary direct communication links with remote gateways of the required bandwidth.

Satileon's IPSKY family of hubs comprises a series of flexible, scalable and modular hub solutions for satellite service providers desiring to deliver the highest quality broadband satellite service in the most cost effectively manner.

The modular design and inherent flexibility of IPSKY enable a single hub to support numerous satellites and transponders, taking advantage of non-contiguous space segment. IPSKY customers can start at a low entry level with a PAMA (Permanent Assignment Multiple Access) hub for small networks and invest as they expand. With time, the IPSKY PAMA hub can be transformed into a full MacroHub that supports a network of thousands of remote gateways. With IPSKY scalable architecture, your investment grows together with your network.

With IPSKY service providers can lower equipment and operating costs while increasing revenues and profits - all while delivering reliable andthe highest-quality broadband satellite service.

+ All IPSKY hubs can be expanded in the field to support more bandwidth and terminals.

* All IPSKY hubs are field upgradeable to multi-transponder, multi-satellite level, as well as to the next product level, i.e. PAMA to Compact or Mini, Compact to Mini etc.

Satileon's IPSKY remote gateways support advanced IP routing features, such as VLAN Tagging for interconnection to MPLS networks and traffic separation. They also feature an embedded IP Acceleration to enhance browsing and TCP application speed. In parallel, the gateways' acceleration applies multiple data compression techniques to substantially reduce the bandwidth requirements of IP traffic over satellite.

IPSKY remote gateways are divided into compact and professional series. Both series enable broadband applications featuring high throughput for both inbound and outbound traffic. IPSKY remote gateways vary in their inbound and outbound capabilities.

IPSKY's advanced and cost-effective technologies make it a market leader in the broadband satellite communications arena. Developed by Satileon, IPSKY was designed to provide the highest bandwidth efficiency and service quality and flexibility.

IPSKY comprises a set of state-of-the-art technologies aimed at providing the highest quality broadband services in the most efficient manner. Among them:

BM-FDMA - Burst Mode-Frequency Division Multiple Access - Based on the advanced Multi Channel Demodulator, this unique access scheme makes IPSKY return channels more efficient, reliable and stable, and thus jitter-free. In addition, BM-FDMA offers on-demand variable bandwidth SCPC-like connectivity to any remote gateway in the network. Unlike TDMA, which works with shared carriers, BM-FDMA's dedicated carriers are instantly erected upon demand when a remote gateway needs to transmit. This reduces the size and cost of the ODU (antenna and BUC) as it can be sized individually for each remote gateway each according to their respective maximum transmission speed. In contrast, with TDMA, ODU must be sized according to the aggregated transmission speed of a group of remote gateways. BM-FDMA is well suited for all broadband and real-time applications.

BoD - Bandwidth on Demand - Implemented in both the IPSKY hub and remote gateways, BoD dynamically adjusts the channel rate, bandwidth and   power level according to the traffic rate required by the remote gateway. By allocating only the required rate for connected remote gateways, IPSKY's BoD enables savings of up to 80% in satellite resources. BOD also determines the appropriate transmission scheme best suited to the amount of data being transmitted - BM-FDMA or BM-RA - and makes IPSKY a true multi-service platform. To preserve link quality and immunity to bad weather, BoD offers Automatic Power Control (APC) and Traffic Rate Control (TRC). These features adjust dynamically and individually to each remote gateway based on Eb/No and Bit Error Rate (BER) readings

BM-RA - Burst Mode Random Access - Based on a burstable unslotted aloha traffic carrier, BM-RA is suited for the transmission of small packets generated by narrowband applications such as credit card transactions, SCADA/Telemetry and others. networking

MCD - The Multi Channel Demodulator pioneered by Satileon introduces the concept of bandwidth processing, reducing deployment costs while retaining SCPC quality. Traditional MF-TDMA systems use single carrier TDMA receivers at the hub for receiving return channels and sharing bandwidth over time in pre-defined "time-slots". In contrast, the MCD enables flexible sharing of bandwidth across the allocated satellite frequency range. This takes place over multiple, simultaneous, different-sized carriers erected, upon demand, by the MCD

DVB-S / DVB-S2 - IPSKY supports both DVB-S and DVB-S2 for outbound transmission. Due to its efficient DVB-S2 LDPC coding and higher modulations, DVB-S2 saves up to 70% in bandwidth over DVB-S. IPSKY's hub and remote gateways were designed to support Constant Coding and Modulation (CCM), Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM), combined with hub-managed Automatic Uplink Power Control (AUPC).

IP Broadband Optimized - IPSKY provides transparent network connectivity for applications using IP, automatically routing the data via satellite.

Quality of Service - IPSKY provides quality of service based on applications and IP addresses. High priority is placed on assuring real time and business critical applications.

VLAN Tagging/ MPLS - This feature enables both traffic separation as well as seamless integration to terrestrial MPLS networks.

IP Acceleration and Compression improves applications speed, reduces the required bandwidth and improves user experience in interactive applications.
