Beyond .11n

Last May the 802.11 group convened the Very High Throughput Study Group to scope out what comes after .11n. One motivation for starting the group was to respond to a call for proposals for Gbit-class wireless networks from the ITU. Craig Mathias of Farpoint Group, one of my favorite wireless analysts, believes the group will ultimately opt for some form of 60 GHz networking, but we shall see.

For the last few months the group has been listening to presentations from AT&T, Intel, Motorola, Nokia and others. I haven't looked through them all, but as part of a story that mentioned VHT SG I did read a couple of them.

The one that struck me the most was from an AT&T Labs researcher, calling on the group to get involved in Terahertz-class regulatory decisions underway in Europe that could cut commercial interests out of that spectrum band. Terahertz transceivers are already in the works from startups such as Phiar Corp. the presenter noted. Like my colleague Patrick Mannion told me years ago—before we even started talking about .11n—we are going to be writing a lot about this wireless stuff for years.
