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

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

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

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

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

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

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