ROMANTIS Cellular Backhaul
Cost-effective backhaul solution for African mobile operators
Cellular Backhaul via Satellite
o

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 capacityhungry 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

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 miniHub and flexible TDMA/SCPC terminals
o Easy to install and operate hardware with
remotely managed operations

BTS / Node B
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 colocated equipment (Wi-Fi, Broadcasting, maintenance)
Savings of dynamic bandwidth assignment
o
o
o
o
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 TCH per 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 on Erlang B calculations for Pb=2%
