Consolidation

• Operators
• Intelsat announced its buying Panamsat Aug 2005
• Still to be approved
• Combined company would dominate intl market (55
  satellites)
• Americom -gt GE -gt SES
• Larger Operators are getting larger
• Smaller Operators survivability

DLSN (Puerto Rico)

• Distance Learning Saltellite Network
• Funded by No Child Left Behind project
• Provides video conferencing, internet, data
  transfer and Video broadcast capabilities to 100
  training centers of the Dept. of Education of PR
• DLSN is geared toward training the educators and
  the students
• Promotes interaction between groups
• Hub facility (Linkstar TDMA platform) is in Mtn
  View
• Separate project in PR provides basic internet
  to 1500 schools (not by Vitacom)

24
DLSN (Puerto Rico) 2

• Technology used
• Satcom network by ViaSat Linkstar
• DVB-TDM outbound 7Mbps
• Several inbounds at 650kbps TDMA
• VCON video conferencing
• Separate one way video broadcast 3Mbps
• Approx 12MHz for 100 nodes, i.e. 120kHz per node
  (excludes video bdcast)
• Terminals 1.8m antenna, 2W BUCs, IDU, IRD, VCON

25
Systems Engineering Aspects

• Modem Performance Improvements
• Higher Level modulation
• QPSK, 8PSK, 16QAM
• (bandwidth efficiency)
• High Coding gain Encoding
• (power effciency)
• Transponder Resource Mgmnt
• Optimization of satellite capacity

• C vs Ku vs Ka band
• Rain attenuation
• Terminal size
• BW cost
• coordination
• Antenna Size
• Small antenna reduces terminal cost but increases
  recurring cost
• Small antenna easy to transport and install but
  reduces link availability

Internet via Satellite

• Thin route
• Based on Linkstar TDMA product. Ku Band
• Many combos downstream/upstream
• 128kbps/32kbps to 1Mbps/512kbps various levels of
  CIR
• From 80/mo to 2,000/mo
• IP applications voice, data, surfing
• Terminal cost around 2K
• BW Sizing and Costing is a major task!!

• Thick Route (backbone)
• SCPC/SCPC asymmetrical
• Cband for higher reliability
• DVB down with SCPC up
• DVB down one way (terr return)
• Typical data rates
• 256k, 512k, 2Mbps, 8Mbps
• Pricing around 2K/mo/Mbps
• Terminal Cost 10K and up

29
Rural Internet Mexico

• e-Mexico
• 2000 nodes, phase 1 (Interdirec-Linkstar)
• Basic internet access only
• 40MHz available (20 kHz /node)
• Subsidized satellite BW
• Poor performance network saturation
• Phase 2 awarded to Telmex (Hughes technology)
• Is it self-sustainable ?

30
Rural Internet Colombia

• COMPARTEL
• Various stages (4,000 nodes)
• Gilat awarded most of the initial phase
• Comsat and Andinet stage B
• Phase 2 recently out for bids
• Interesting formula
• Government grants regulatory license to winner
• Winner operates network, collects, etc
• Performance specifications need to be met
• Winner is that who requeires the smallest
  subsidy

31
Rural Internet

• Internet kiosks for public use
• If telephony offered on top, it adds significant
  value, but demands much more BW
• Cyber Café very common in Lat Am
• Use of Consumer Products in this market distorts
  prices and produces disappointments
• Combine Satcom WiFi to provide wider coverage
• Overall Economics
• Incumbent Telcos Reaction
