The same modulation formats have been used for more than a decade. With today’s bandwidth limitations, however, an upgrade is certainly welcome. Following three years of research and engineering, TM Technologies, Inc.—a division of Medusa Scientific—has successfully demonstrated a new modulation technology. Named Transpositional Modulation (TM), this approach promises to provide true DC response while remaining transparent to other modulation formats.

According to the company, TM can be added to existing modulation formats or act as a standalone format. Supposedly, it permits the transmission of much higher data rates than those possible with other forms of modulation alone. In addition, TM is immune to Doppler effects while providing the capability to combine multiple, different data streams on a single TM signal. The company claims that it generally provides the capability to meet the data rate demands of ultra-high-definition (UHD) video and other data-intensive RF requirements.

The company expects to complete a prototype satellite modem for testing this month. That modem is expected to dramatically increase “bent-pipe” data rates. It includes an Ethernet port for adding other signals into the transmitted data stream. With a September goal in mind, Medusa’s scientists also are completing a demonstration of 4K UHD video streaming via a single-signal transmission. The company has begun seeking global commercialization partners to help with the implementation of the technology into the broadcast, telecom, satellite, and wireless-Gigabit (WiGig) industries.
