This upgrade and expansion, which is 4G/LTE enabled,
will leverage Comtech EF Data’s multi-layered
optimization approach, teaming the CDM-625A Advanced
Satellite Modem with the Memotec RAN Optimization CXU
Series to achieve the maximum net efficiency possible on
the MNO’s links. The Comtech EF Data solution was chosen
due to field-proven reliability and past performance,
and will enable the operator to expand its network and
increase voice and data throughput by at least 500 Mbps
without requiring the increased operational expense of
additional satellite bandwidth. The operator currently
supports several Gbps of traffic on multiple satellites
in both C-Band and Ku-Band. This selection strengthens
Comtech EF Data’s dominant position in terms of total
Gbps supported for satellite backhaul links around the
globe, with tens of Gbps of traffic being supported
within the Asia-Pacific region alone.
The CDM-625A platform was chosen to enable the
network expansion due to its net spectral efficiencies
coupled with its ability to best support traffic
optimization at mid-range data rates. The CDM-625A
leverages the recently announced VersaFEC-2 Forward
Error Correction and Modulation technique along with the
bandwidth compression technology and 5% carrier roll-off
to provide the highest Mbps/MHz ratios in the industry.
The VersaFEC-2 coding method was purpose-designed to
avoid the latency penalty associated with the DVB-S2X
standard for medium rate aggregation links. By providing
80-90% less latency than the standard, VersaFEC-2 allows
the applications running upon these networks to function
optimally. For IP links, the CDM-625A leverages its
intelligent header compression and lossless payload
compression engine to ensure that only essential
information is transmitted across the satellite links.
For non-IP links, the CXU-1240E performs the traffic
optimization functions, providing 2G/3G aggregation
techniques that remove unnecessary information from the
satellite links, maximizing net efficiencies while
minimizing operational costs per Mbps.
The existing Comtech EF Data hardware used in the
operator’s production network plus the equipment
purchased on this order are capable of being managed by
the Comtech EF Data Integrated Management System, which
provides the level of network insight required to run
optimal networks. NetVue™ provides a single intuitive
graphical user interface that acts as a user-friendly
front-end to monitor and control network equipment. It
features a robust, comprehensive network management and
analytics engine that allows users to intelligently
maximize resources, ensure network uptime and provide
the elevated levels of service that are required to
support fixed and remote sites in the field.
“Our market-leading, intelligent optimization
techniques provide efficiencies that are leveraged by
mobile network operators across the globe to
cost-effectively upgrade networks, increase throughput
per site and provide enhanced services to their end
users,” commented Fred Kornberg, President and Chief
Executive Officer of Comtech Telecommunications Corp.
“We are pleased that our solution suite will enable this
Asian MNO to upgrade and reliably expand its network
within its current cost structure.”
