  1. Satellite Connectivity Connecting the Caribbean Emergency Communications & Disaster Preparedness Michael Gold Vice President Comtech EF Data

  2. Connecting the Caribbean

  3. Global Mobile Trends • Mobile is enabling connectivity for many people for the first time in their lives • GSM • 3+ Billion GSM subscribers exist worldwide • 700 mobile operators across 218 countries and territories of the world are adding new connections at the rate of 15 per second, or 1.3 million per day • Emerging markets represent 85% of new connections today • Over 90% of the Earth's population will be covered by mobile networks • To keep capital and operating costs down, new and innovative ways must be proposed to meet connectivity goals • The fast pace of cellular network roll-out and take-up around the world is creating mounting coverage challenges for mobile operators Sources:

  4. Satellite-Based Cellular Backhauling • To enter markets beyond large city limits and to blanket large regions with cellular services quickly, satellite backhaul can efficiently extend reach • To tap into new customer markets with tight and regulated timeframes, mobile incumbents and new operators can build networks with satellite infrastructure • Satellite can beat many fiber, cable or wireline deployment schedules by weeks or months • Technology advances (compression techniques, IP-over-satellite delivery and optimized network topologies) are catalysts to fuel the market for cellular backhaul via satellite Source:

  5. Satellite-Based Cellular Backhauling • Market is driven by rapid expansion of cellular networks in developing economies of Africa, Middle East, Latin America and Asia • Mobile operators are using satellite space segment to backhaul traffic between remote cell sites and the network’s Mobile Switching Center • Satellite is most popular in greenfield operations – it’s the quickest and most cost effective solution for RAN deployment • Total number of cellular sites backhauled by satellite is predicted to grow to 35,000+ sites globally by end of 2010 (CAGR = 28%) Source:

  6. Connect the Caribbean • Demand for satellite capacity is straining the bandwidth supply • In Latin America, operators will launch new satellites during the next 2-5 years to meet the new demand over the next 10-15 years • However, the growth of government and commercial applications over satellite requires immediate solutions for satellite transponder capacity • The capacity challenge can be countered with advanced satellite technologies • Advanced forward error correction • Higher order modulation • Bandwidth compression

  7. Emergency Communications & Disaster Preparedness

  8. Natural & Man-Made DisastersAn Unfortunate Reality • Recent examples around the globe have proven that communications systems can be severely affected when disaster strikes • The financial impact of network outages can be considerable • Even the most reliable terrestrial networks are susceptible to outages because they lack true path diversity and have common points of failure • Establishing first response connectivity of voice, data and video is a necessity • And, maintaining continuity of business communications is critical for sustained operations

  9. Satellite Communication Systems An Essential Component to Disaster Recovery • Enables communications restoral more rapidly than terrestrial systems • Allows enterprises and government agencies to respond quickly if satellite communications systems (fixed or mobile) are the backbone of emergency communications networks • Facilitates instantaneous communications between hospitals, headquarters, supply centers and remote locations • Minimizes downtime of back office operations

  10. Disaster Recovery &First Responder Needs • Rapid Deployment • Satellite based systems are perfect for instantaneous deployment to the disaster site • Systems can be organized in vehicles or in transportable, self-contained cases • Interoperability & Standards • IP based platforms provide a seamless way to integrate Internet, e-mail, voice, video, file transfer applications between agencies • Ruggedness • Communications via satellite can be provided in extremely harsh environments • Reliability • Satellite technology provides a highly reliable mechanism for one-way or two-way communications • Security • Satellite links must provide secure communications

  11. Business Continuity Needs • Redundant communication links between corporate offices locally, regionally, nationally and globally • Critical connections to off-site back-up servers, computers, and databases • Businesses to “get back on their feet” quickly after a loss of terrestrial/wired communication

  12. Satellite Services Meet the Need • Satellites meet the key requirements of an effective recovery plan • Physical path diversity from the exiting network • Fast service availability – within 24 hours • Scalable bandwidth that can adjust to changing capacity needs • Flexible service support • Bandwidth/capacity available for extended time frames • Connectivity to primary and backup data centers • Last-mile bypass of disaster-affected area • Ability to relocate easily • Rapid deployment • The network can be leveraged to support applications other than backup • Deployment of advanced satellite technologies make it more cost-effective • Advanced forward error correction • Higher order modulation • Bandwidth compression

  13. Advanced Satellite Technologies Forward Error Correction Higher Order Modulation Bandwidth Compression

  14. Forward Error Correction & ModulationSpectral Efficiency vs. Eb/No

  15. 3/4 7/8 Viterbi + Reed Solomon Turbo Product Coding Viterbi + Reed Solomon Turbo Product Coding Eb/No (dB) Bandwidth Efficiency (bps/ Hz) 5.2 1.35 4.0 1.50 6.5 1.58 4.2 1.75 Turbo: Less Power Turbo Less BW Turbo Product Coding • Turbo Product Coding • Lower Eb/No requires less power • Higher efficiency uses less bandwidth • Block size most important for coding gain

  16. Low Density Parity Check • Basis of DVB-S2 standard • Third-class of Turbo Code • Turbo Product Coding (TPC) • Turbo Convolutional Coding (TCC) • Iteratively decoded block code • Performs 0.7 dB – 1.2 dB better than TPC at low FEC rates (3/4 and below) • While coding gain is greater, processing delay can be an issue

  17. Benefits of AdvancedForward Error Correction • Advances in FEC can offer ≥3-5 dB of performance over currently used methods • 3 dB of Coding Gain can: • Reduce required bandwidth by 50% or • Increase data throughput by a factor of 2 or • Reduce antenna size by 30% or • Reduce transmitter power by a factor of 2

  18. Bandwidth Compression DoubleTalk® Carrier-in-Carrier® bandwidth compression allows sharing of same satellite bandwidth by both terminals 18
