Technologies
They are the dominant SCPC satellite modem developer and a formidable participant in RF products, RAN/WAN optimization, managed bandwidth and VSAT offerings. They invest significantly in R&D, developing innovative technologies through new product design and incremental improvements to existing products. Some of the technologies developed / implemented by Comtech EF Data are:

DoubleTalk® Carrier-in-Carrier® – allows full duplex satellite links to transmit concurrently in the same segment of transponder bandwidth. When combined with the advanced FEC & modulation, it improves transponder utilization and saves OPEX.

Automatic Carrier-in-Carrier Power Control (ACPC) – allows modems on both sides of a Carrier-in-Carrier (CnC) link to automatically measure and compensate for rain loss while maintaining a fixed PEB on the satellite during all conditions. It also enables CnC modems to share link margin.

Forward Error Correction (FEC) – traditional and advanced methods, such as VersaFEC®, Low-Density Parity-Check Codes (LDPCs), DVB-S, DVB-DSNG and DVB-S2, and 2nd Generation Turbo Product Codes (TPC).

Modulators / Demodulators – their products use ASIC and FPGA modulator and demodulator designs, and support BPSK, QPSK, OQPSK, 8PSK, 8-QAM, 16-QAM, 64-QAM, DVB-S2, 16APSK and 32APSK.

Adaptive Coding & Modulation (ACM) – converts link margin to an increase in the data throughput of satellite links.

Radio Access Network (RAN) Optimization – reduces satellite bandwidth required for mobile backhaul and provides user control over the level of optimization and link quality.

Integrated Router with header compression, payload compression, ultra low overhead streamline encapsulation and Quality of Service (QoS) – enables real-time traffic and other low priority traffic to co-exist on the same link without impacting the voice quality or delivery of mission critical data.

AutoEQ – supports amplitude and group delay equalization over the satellite system.

Dynamic Single Carrier per Channel (dSCPC) – automates bandwidth utilization and provides the low-latency, low-jitter dedicated SCPC connection when needed for real-time applications.

Daisy Chain Redundancy Switching – integrated switching technology that removes the relays associated with a centralized protection switch tray and distributes them across the individual converters.

Carrier ID Using MetaCarrier™ – addresses the problem of interference by embedding and detecting Carrier ID on video and data satellite carriers.

Patents
Comtech EF Data holds an impressive number of patents that set them apart from their competition. A summary of their active patents is available at http://patents.comtechefdata.com.

Markets Served
Their products are utilized by organizations in a variety of industries, including satellite service providers, telecommunications operators, maritime, oil & gas, disaster recovery, Internet service providers and broadcasters. Governments and military entities also have their products deployed to support fixed, on-the-move and at-the-pause communications.

In-House Manufacturing
Comtech EF Data’s headquarters are in Tempe, Arizona USA where its campus includes a full manufacturing plant. Many other satcom companies outsource production. However, since Comtech retains most product processes in house, they can reduce turn-around times and provide the highest quality and reliability. Their facility is compliant with MIL-STD-1686, ANSI/ESD 20.20 and IPC/EIA J-STD-001, and their products are built in accordance with IPC-A-610, class 2 and 3.
