New Era of “Data-Centric” Backhaul
for Telco/Celco
Mobile-Cellular Subscriptions
• # of mobile-cellular subscriptions worldwide is approaching population
on earth -> will reach almost 7 billion by end of 2014
• >50% of the subscriptions (3.6 billion) are in Asia-Pacific
• Africa & Asia-Pacific are the regions with the strongest growth

The Rural Conundrum
Increased need for Efficiency compared to urban
- Market
Requirements
- Government
Regulations

Technology:
-GSM
- Backhaul
Higher OPEX
Rural
Mobile
• Deploying Infrastructure with
questionable ROI (lower ARPU,
customer density, High OPEX)
• Higher Transportation costs
• Tower, Antenna,
Maintenance...
• Energy costs:
• OPEX (Diesel) or CAPEX (Solar)
• Site Security
• Theft, vandalism
Providing service in low density areas is challenging

What Really Matters to
Mobile Network Operators (MNOs)?
TCO More Services Lowest
OPEX Lowest CAPEX
Control of Total Cost of
Ownership
Offering more services
with the best TCO
When using
C-, Ku-, Ka-Band, GEO,
MEO & HTS
Most efficient Bit/Hz
Re-usable on different
satellite capacity &
services

Minimize Latency & Jitter
• Earth station digital equipment needs to minimize
both latency and jitter
– On board processing minimizes IP packet delays
– Latency not just an audio issue – 3G and 4G LTE systems
can be sensitive
• Jitter has significant impact on perceived voice/2-way
video quality
11
Optimize the E1 RAN
• Best to support integrated E1 RAN optimization
– Abis Optimization
– TDM compression
– Support simultaneous E1 and Ethernet operation in Hub
Spoke topology
• Traffic trending
– Ingress (E1 & LAN) and egress (WAN) traffic
– Link quality

The “Aggregation” Requirement
15
• Aggregation nodes are typically higher bandwidth nodes supporting greater
than 10 Mbps and supporting combination of higher number of TDM + IP
backhaul
• RAN/WAN Optimization - CX-UA: can optimize up to a full STM1 of E1
based traffic and convert it to optimized IP traffic. Typical experience: 1
STM1 of Abis => 45 Mbps IP (3:1)
• Traffic Shaping - Stampede FX: optimizes IP traffic stream, manages
CDM760 ACM, and enforces QOS on ACM variable bandwidth.
• Modem – CDM-760: High modulation DVB-S2-EB1, CnC
IP Traffic:
•ABISoIP
•Iub
E1 Traffic:
•ABISoE1

Trending Access Requirements
16
• Today’s “Mobile Access” requirement has shifted from standard 2G
TDM (E1) backhaul to mixed TDM/Ethernet backhaul.
E1 E1 E1 Ethernet Ethernet
CDM-625A with E1 +
Ethernet SUBMUX
CDM-625A with
E1
CDM-625A + Memotec CXU
across IP/Ethernet modem
Static BW allocated
regardless of
actual traffic load
Static BW allocated
for each service (no
sharing of satellite
resources)
Single BW defined for both
services with shared access
via QoS. Also, enables
additional BW capability via
ACM since backhaul is
exclusively IP/Ethernet.
Successful 2G to 3G Migration
• An MNO in Pakistan was using CDM-625
with E1 interface for 2G
• Successfully migrated to IP transport for 3G
by adding Packet Processor into modem
– VLAN
– QoS to differentiate signaling, voice and data
– Header compression
– Payload compression
• This migrated satellite 3G network will carry
more than 500 Mbps of voice and data
traffic - Without needing extra bandwidth
17
Over Satellite
• LTE backhaul has been deployed by a major North American
mobile network operator
• LTE network vendor - Alcatel Lucent
• 20 Mbps satellite link with DoubleTalk® Carrier-in-Carrier®
• Able to achieve maximum throughput for UDP and TCP/IP
18
SatCom Economics –
“Total Cost of Ownership”
• Costs typically associated with
satellite communications
– Operating expenses
Satellite space segment
Recurring license fees and
taxes
Support and maintenance
– Capital (Fixed) expenses
Ground equipment, codec,
routers, switching
equipment, modems,
converters, RF, HPA,
antennas
Site preparation, civil works,
one time license fees
