A written testimonial is a gift to any company receiving such positive, reflective statements of support for a particular product or line of products. Comtech EF Data has just received such from ST Teleport. That company happens to be a full-service satellite communications solutions provider. ST Teleport conducted performance measurement testing of the CDM-Qx Satellite Modem with DoubleTalk Carrier-in-Carrier (CnC) technology. The reason for the test was to study the bandwidth and power efficiency of the product in a Single Channel Per Carrier (SCPC) link.
The results revealed a bi-directional link with 512 Kbps data rate will use 921 kHz of satellite bandwidth without CnC. With CnC, the link used 453 kHz, which represents 50 percent bandwidth savings. This means for each 2.048 Mbps bi-directional SCPC link, the total bandwidth savings will be 1.8 Mhz. Through an analysis of cost factors, the end result by ST Teleport revealed a payback period of 3 months, with savings of some US$43,200 annually. The testimonial was signed by Mr. Peter Heng Trech Chye who is the Director of Technical Services for ST Teleport Pte Ltd. who operate their earth station complex in Singapore and supply services for the Indian and Pacific Ocean regions.
