Photron, a company based in Singapore, has announced that they are producing Ultra Spectral Modulation (USM) chips, achieving a transmission speed of 100 bits per second for each Hz of bandwidth while consuming very low power.
This new technology utilizes FPGA (Field Programmable Gate Array) in its hardware platform. As a result, USM operates up to 25 times more efficiently than the leading 3G technology in the U.S., which is EV-DO. Larry Garcia, a senior technical advisor for Aerotelesis in Los Angeles, stated that they plan to implement USM technology in the near future.
Photron did not provide detailed descriptions of USM, only mentioning that it is a reasonable combination of phase modulation, amplitude modulation, and an ideal digital filter. Additionally, they did not specify the operational range of USM. Although it has been compared to EV-DO technology, experts believe that the coverage of USM will be significantly more limited.
Furthermore, the announcement regarding USM is reminiscent of what XG Technology claimed about xMax last year (7.4 Mbit/second/MHz/Watt), even though it was presented in a different format.
