• 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

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

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%)

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
• 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

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

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
10
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
11
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
• 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
16
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
