High Throughput Satellite Capacity over VSAT Technology Helps Network Operators to Lower Costs

Comtech Telecommunications’ Arizona-based subsidiary, Comtech EF Data along with Supernet Limited, its partner in Pakistan, has migrated a Mobile Network Operator (MNO) customer to new High Throughput Satellite (HTS) capacity over VSAT while leveraging existing infrastructure equipment.

Challenged by low Average Revenue per User (ARPU), MNOs (Mobile Network Operators) struggle to drive down costs while delivering effective services over VSAT. By teaming with satellite service providers and system integrators, Comtech is able to deliver solutions to address this challenge.

Earlier this year, Supernet Limited and its MNO client, upon executing the migration plan, realized a marked decrease in backhaul expenses. This significantly improved the MNO’s competitive position and the profitability of service delivery over satellite. These savings were made possible through a combination of migrating its services to HTS (High Throughput Satellite) spot beam capacity, updating Comtech EF Data CDM-625 satellite modems via FAST code to enable higher order modcods and throughput, and through Supernet’s exceptional customer support efforts. In the process, the MNO client realized the remarkable equivalent of 11 bits/Hz in their use of satellite capacity which translated into the OPEX savings on backhaul expenses and added room for 3G services. Without the updates and migration this would have been in the range of 3 to 4bits/Hz, similar to what could be expected from a competitive solution.

Comtech EF Data has supplied its award-winning and bandwidth efficient satellite modems with optimization features to Supernet since 2007, and had been extremely successful in lowering the Total Cost of Ownership of backhauling the MNO customer’s traffic over satellite. Some of the leveraged features include industry best VersaFEC Forward Error Correction, the revolutionary DoubleTalk Carrier-in-Carrier bandwidth compression, lower roll offs, 2G/3G IP optimization and 2G TDM by its subsidiary, Memotec. MNO’s 2G/3G IP traffic benefits from the modem’s advanced packet processing capable of providing more than 75,000 packets per second, header and payload compression, and a Quality of Service engine that ensures the highest Quality of Experience for end users. The combined effects of bandwidth efficiency, optimization and processing speed allow the satellite platform to meet the Key Performance Indicators (KPIs) of the MNO.

This successful project offers a great example of the best in breed longevity and best in class low cost of ownership of Comtech EF Data products. It is another example of the benefit of the highly upgradable products offered. Not only can MNOs migrate over to HTS capacity with very little additional CAPEX enabling tremendous OPEX savings, but they can do so while also adding 3G or LTE to existing 2G sites. Comtech modems simultaneously support 2G, 3G and LTE services with built-in optimization through a dedicated packet processor that enable the highest quality of experience and best KPI for MNOs and end user alike.
