...for more than 40 sites in Indonesia. SpeedCast partnered with Comtech EF Data to deliver a highly optimized and efficient cellular backhaul solution for the customer. Cellular backhaul projects are substantially more complex than basic IP network connections, because of the real-time nature of the network. This project was particularly challenging because it involved existing equipment and infrastructure in a geographically distributed environment—all across Indonesia, on various islands. Due to the complexity, most operators have strict service level agreements for performance, to guarantee a high level of quality for their users.

SpeedCast and AJN were selected after extensive testing by the customer to ensure the quality of the provider and solution offered. SpeedCast and AJN’s engineers worked closely with the customer and completed extensive field reports for all sites. With this level of detail, the SpeedCast RF team designed a customized solution, based on Comtech EF Data’s CDM-625 Advanced Satellite Modems with DoubleTalk® Carrier-in-Carrier® and the Memotec CX-U Series RAN optimization products to deliver significant bandwidth savings for the customer, with no degradation in quality.

Comtech EF Data’s CDM-625 Advanced Satellite Modem combines advanced forward error correction with DoubleTalk® Carrier-in-Carrier® bandwidth compression for maximum savings under all conditions. DoubleTalk® Carrier-in-Carrier®, based on Raytheon Applied Signal Technology's patented "Adaptive Cancellation" technology, allows transmit and receive carriers of a duplex link to share the same transponder space. The combination of advanced technologies enables users to minimize OPEX/CAPEX and maximize throughput/availability without using additional transponder resources. The CX-U Series brings together access device and cellular backhaul traffic optimization, offering a variety of interfaces and transmission options.
