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 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 Disasters An 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, , 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 & Modulation Spectral Efficiency vs. Eb/No

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

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 Advanced Forward 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
