In a critical development in the race for UWB market traction, Focus Enhancements announced that it has received Federal Communications Commission approval for its unique Ultra Wideband (UWB) DS-OFDM modulation scheme.
This approval was granted without waiver restrictions that are currently being applied to the WiMedia Standard UWB technology.
The unqualified FCC approval provides Focus with an advantage because it can now commercialize its technology. DS-OFDM UWB radios will be able to use all or any part of the 3.1 gigahertz (GHz) to 10.6 GHz spectrum allocated by the FCC. UWB rates and distances will be significantly increased using DS-OFDM architecture.
Focus claims its silicon can provide rates for 880 Mb/s. Unlike several other companies, Focus has not received WiMedia Alliance certification but it is moving in that direction.
The company's Talaria UWB wireless technology integrates both WiMedia Standard MB-OFDM modulation and its own DS-OFDM modulation. As such, it can talk to both WiMedia and DS-OFDM devices simultaneously. Talaria is also designed to be compatible with the Certified Wireless USB Standard, according to the company.
Six companies recently announced WiMedia Alliance certifications for the PHY levels of their chips. WiMedia Alliance certifies six IC products for UWB interoperability.
"The ability to use DS-OFDM has several significant advantages in the UWB space," said Michael Ngo, vice president of engineering of Focus Enhancements' semiconductor group. "In the U.S., our wireless UWB technology will be able to access all 7 GHz of the available UWB spectrum.
"In Europe, where it looks like UWB will be restricted to the frequency range between 6 GHz and 10 GHz, we will be able to use all 4 GHz of the allocated frequency; and in Japan, we can use all 3 GHz allocated between 7 GHz and 10 GHz."
