Set–Up

OmniGlobe runs the whole network internationally end to end. That means the overall network management, satellite space segment provision, international gateway hub management (the interface of the satellite network to the internet), 24hour network monitoring, procurement of all technical infrastructure, base stations and end user terminals, shipping, spares management, quality control and continuous R&D improvements to the network. We connect customers to the European or North American internet backbone via GEO satellites. Users, otherwise limited to poor quality dial-up (56kb/s) or low speed broadband (256kb/s to 512kb/s), will enjoy almost unimaginable download speeds with total pipe capacity of up to 45Mb/s, and individual rates of up to 6Mb/s.

Our company is unique in two ways; firstly our ability to support our customers and tailor our products to their needs, and secondly our technology IP. We have developed processes that save up to 60% on bandwidth costs and enable our WiMax and pre-WiMax networks to ‘handshake’ via satellite to the Internet in a way that allows exceptionally fast broadband, Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Additionally, we have end-to-end management using our Local Management (LMAN) and Global Management (GMAN) software.

Figure 3 provides an in depth graphical overview of the OmniGlobe Networks (OGN) architecture. The system can be operated anywhere on the planet, with cost-effective rollout options for subscribers numbering from the low hundreds to many thousands per cell, and in both rural and urban environments.

OGNs network architecture is based on widely-available hardware components, used in combination with our state-of-the-art networking and performance enhancement infrastructure software solutions.

Below is an overview of our key products and technologies:

• OmniCenter: A network operations centre including a subscriber management system, 24/7/365 monitoring system, backup and redundancy, and satellite gateways with Internet peering points. The gateways are capable of handling the aggregate traffic from potentially hundreds of WAP sites worldwide.


• Global/Local MAN: Located at either OmniGlobe’s main Network Operations Centre (OmniCenter), or at the customer’s deployment, the intention of the network management subsystem is to integrate many common network monitoring and management features into a single system. Briefly, this software will frequently check the health of key network elements providing a portal to conveniently view device statistics, send alerts in failure situation and automate many routine network administration tasks. Refer to diagram below for more detail.


• OmniLink: Satellite terminals and metered bandwidth over a satellite link based on the DVB-RCS international standard for two-way satellite access. Each terminal includes:


• An outdoor unit (ODU) consisting of an antenna (dish), low noise block (LNB) amplifier and block up-converter (BUC).
• An indoor unit (IDU) consisting of a DVB-RCS modem.



The forward link (from the OmniCenter gateway towards the OmniLink terminals) is capable of transporting up to 45 Mbps of IP data (the capacity of a standard DVB-S carrier) using Time Division Multiple Access (TDMA) to divide the data between different OmniLink terminals. The forward link is capable of providing QoS based on IP and DVB mechanisms. The return link (from the OmniLink terminals towards the OmniCenter gateway) is capable of transporting up to 8 Mbps of IP data using Multiple-Frequency TDMA.




• OmniCell: Long-range (up to 30 km.) wireless access point based on WiMax or pre-WiMax (IEEE 802.16 standard) technology, with OmniLink satellite-based traffic backhaul. End users connect to the access point using small, unobtrusive antennas and customer premise equipment (CPE) modems.



• OmniSpot: Short-range (up to 100 meters) wireless access point based on Wi-Fi (IEEE 802.11a/b/g standard) technology, with OmniLink satellite-based traffic backhaul.



• OmniBoost: An optional low-cost amplifier module that increases (boosts) the radio output power of an OmniCell or OmniSpot WAP in order to extend coverage and enhance non-line of sight (NLOS) wireless performance.



• BOSS: Bandwidth Optimization Subsystem providing proprietary pushing, caching and multicasting software to enhance the end-user experience by allowing popular Web content to be re-used without requiring satellite access, thereby avoiding the latency and delays typically associated with satellite-based solutions while reducing the satellite bandwidth cost.



• PEP: Performance Enhancing Proxies are devices that improve the end-to-end performance of TCP over high delay-bandwidth product links such as satellite. Typically, a PEP breaks down TCP connections into multiple mini-connections adjusting the connection parameters of each in order to overcome poor window sizes and other problems associated with TCP over satellite.

This system is world class and implemented on a case by case bases form a team of exceptional software engineers and management staff. We have worked hard to establish an infrastructure platform for all our customers and work even harder on giving them the right solution, technology and support.
