Last week I went to an ex partemeeting with the FCC on behalf of Pulse~Link, Inc. They are a California company that has developed practical applications of ultrawideband technology. The purpose of the meeting was to let the FCC technical staff know of the existence of this technology because it solves some of the issues they are currently actively engaged with.
For those of you who have never been the FCC it is an interesting process. In a post-911 world the front of the building is blocked by concrete barriers. When you go through security they not only check your ID, but they give you a badge with your picture on it. Whenever you officially meet with the FCC staff or Commissioners to discuss anything industry related it’s considered an ex parte meeting. This means that a formal letter must be filed soon after the meeting to document who you met with and what you discussed. I like this process because it stops the large companies from lobbying staff without at least documenting the meeting. I have gathered some interesting information for my blog from the memos generated from ex parte meetings.
But this is a technology blog, so let me talk about the technology. Ultrawideband (UWB) is a technology that the FCC promoted for wireless applications in 2002 in Docket 02-48. Ultrawideband works at very high frequencies and is similar to 802.11ad in the wireless world. But Pulse~Link has been able to take this technology and put it onto any wired medium – coaxial cable, telephone copper or even electric wires. They are marketing this is a chipset, under the brand name CWave that can be used in a wide variety of existing devices.
The most exciting uses of the technology are on coaxial cable, and it is these uses that got me to this meeting. I see this as a disruptive and transformational technology. The best way to think of UWB is as DSL over coax. It can provide a separate and distinct Ethernet path far above the cable and data that are normally sent over coax, without any interference.
