Ultra Wideband – the coming wave
In early 2002 the FCC issued a Report and Order authorizing the use of 7.5 GHz of bandwidth for very low-power, ultra wideband (UWB) communications. This is the first significant unlicensed spectrum allocation since the ISM bands, which led to the widespread adoption of wireless LANs.
Very high speed wireless communications will enable a number of applications and market segments including the wireless complement to USB and Firewire/1394 ports, multimedia applications, high-capacity data networks, and low-power communication for battery-operated devices. Along with the applications and market drivers we will highlight what is fundamentally different about the ultra wideband spectrum allocation, the potential pitfalls, and the capabilities and differentiation that it can engender.
Rajeev Krishnamoorthy is founder and CTO of TZero Technologies, a wireless broadband fabless semiconductor company. He has over a decade of experience in the development of advanced wireless communications systems and has worked on research and product development in the areas of wireless LANs, cellular telephony, and multiple-antenna systems.
Most recently, Rajeev was Vice President of Technology at Iospan Wireless, where he led the team that developed and delivered the first commercial multiple-antenna (MIMO) chipset and wireless system. Prior to Iospan, Rajeev was at Bell Labs (AT&T/Lucent/Agere). As part of his tenure he spent a few years at the wireless LAN division of Lucent in Utrecht, Holland, where he co-invented and developed the high-speed version of the extant system which Lucent proposed to the 802.11 standards committee resulting in the current 802.11b (Wi-Fi) standard. Rajeev received his PhD from Cornell University and his BS from Caltech.
Our work is centered around a series of Focus Areas that we believe are the future of science and technology.
We’re continually developing new technologies, many of which are available for Commercialization.
