A mobile network operator based in Latin America will be expanding its satellite mobile backhaul network using more than a million dollars worth of satellite communications infrastructure equipment from Comtech EF Data Corp.


In addition to expanding its existing 2G, 2.5G, and 3G networks, the Latin American mobile network operator also plans to offer 3G HSPA mobile broadband services to consumers in rural and remote areas. To this end, it has ordered satellite modems, redundancy switches, and both indoor and outdoor frequency conversion systems from Comtech EF Data.

The company specified the CDM-750 Advanced High-Speed Trunking Modem and the CDM-625 Advanced Satellite Modem, the latter of which has set the de facto standard for mobile operators. The two Comtech modems improve the efficiency of bandwidth, optimize links, and reduce operating expenses.

The CDM-750 is a point-to-point trunking modem designed to deliver the highest and most efficient throughput. Its space segment saving capabilities keeps overhead to a minimum while also accomodating the most demanding mobile backhaul links. In comparison, the CDM-625 maximizes savings whatever the condition by combining DoubleTalk Carrier-in-Carrier bandwidth compression with VersaFEC and Low Density Parity Check codes that perform advanced Forward Error Correction.

Also included in the purchase were companion redundancy switches and indoor and outdoor frequency conversion systems.
