  1. ROMANTIS Cellular Backhaul Cost-effective backhaul solution for African mobile operators

  2. Cellular Backhaul via Satellite • Cellular Backhaul provided most of the growth in SCPC segment last years • Backhaul via TDMA networks is getting more and more popularity because of penetration to rural areas with low and unpredictable cellular traffic • Cellular Backhaul is the most capacity-hungry application, requiring 512-1024 kbps per site • Mobile providers require cost-effective backhaul solution to perform USO obligations, that is now part of new 3G/LTE licenses in many countries • African and Asian markets are the most perspective regions for Cellular Backhaul, because of actually low penetration COMSYS VSAT REPORT, 2012

  3. Requirements • Small-to-medium size star-topology network with local Gateway • Support either for IP backhaul and for 2G E1 A-bis protocol • SCPC dedicated connectivity for developed sites with intensive traffic and TDMA backhaul for undeveloped sites and USO • Independent infrastructure with in-country Hub, that should be located within specific region • Cost-effective solution with inexpensive mini-Hub and flexible TDMA/SCPC terminals • Easy to install and operate hardware with remotely managed operations

  4. ROMANTIS UHPProvider-class VSAT technology • Any modes and topologies: SCPC, TDM/SCPC, TDM/TDMA, Hubless TDMA • DVB-S2 VSAT technology with LDPC coding in TDMA channel • Innovative TDMA protocol with proven efficiency of 96% • Ultra-low latency VSAT system with round-trip delay about 570 ms • Support of VLAN, multi-level QoS, TCP acceleration • Fast network startup — network is ready for use in less than a minute • Low power consumption allows using terminals with alternative power sources • Compatible with C, Ku and Ka-band * With external RAN optimizer

  5. SEVISCellular Optimization • Cuts Backhaul Bandwidth on A.bis/A-ter by 50% or more • Lowers network OpEx and CapEx • Converts traffic from TDM to more efficient packet-based IP • Suitable for both satellite and terrestrial connections • Voice quality and data services (GPRS, EDGE) are preserved • Supports 2G, 2.5G and 3G Networks • Optimizationforanycodec: HR, FR, EFR, AMR • Optimizes all GSM protocols: A.bis, A-ter • Interoperabilitywithequipmentfrommajor GSM switchvendors • Fully compatible with Romantis UHP

  6. Satellite Backhaul Network TDM TDMA SCPC • Hub transmits aggregated TDM carrier to all network terminals • Terminals transmit via shared TDMA channels or may use dedicated SCPC link when reasonable (heavy traffic etc) • The same network provides backhaul for 2G/3G/LTE traffic • Satellite may provide broadband connectivity for other co-located equipment (Wi-Fi, Broadcasting, maintenance) E1 / IP UHP TDM/TDMA mode BTS / Node B E1 (A-bis) UHP HUB E1 / IP BSC/RNC UHP TDM/SCPC mode BTS / Node B

  7. Savings of dynamic bandwidth assignment • Aggregation of traffic of several Base Stations within shared satellite trasport allows reducing overall bandwidth consumption • The maximum effect of 40% could be achieved when connecting >10 BS with low traffic (8-16 TCHper BS) • Such savings remain substantial (10%-25%) even for sites with essential traffic (> 24 TCH in BC) • The resource disposed due to such statistical multiplexing can be used for data transmission and/or to increase network throughput during peak hours Based onErlang B calculations for Pb=2%

  8. SATELLITE CAPACITIESINTELSAT 22 • Provides capacity for growth over Africa, the Middle East and Eurasia • Wide coverage and accessibility of European teleports • High-power transponders allow using low-cost, small-aperture terminals • Ideally suited for Cellular Backhaul networks

  9. SATELLITE CAPACITIESExpress AM8 • The newest satellite of Russian Satellite Communications Company • Provides capacity for growth over Africa, the Middle East and Europe • Wide coverage and accessibility of European teleports • High-power transponders allow using low-cost, small-aperture terminals • Ideally suited for Cellular Backhaul networks • Available in 2013
