What WIFI-Direct looks a whole lot like is a solution desperately searching for a real problem. One big deal thing that has been completely ignored is security, which may not matter to gamers, but those downloading photos or other files may not wish them to be available to the general public. Encryption is a burden that uses battery power and often slows the transmission process, so it is not likely to be included. Besides that, it will be quite funny when the entire 2.4 GHz spectrum becomes filled and only the strongest signal gets through. That will indeed be an interesting scene.

So how will Wifi-direct devices pair? on Bluetooth most of times is a simple PIN number exchange, but when I do a Wi-Fi connection to a hot spot, many times the WEP key isn't that easy isn't it... so... isn't the code going to be a little more difficult than current bluetooth?

Eric, The points you are bringing are very valid. But I am not sure handset manufacturers are ready to integrate another complex radio such as UWB. I think Bluetooth 3.0+HS is a better candidate than Wi-Fi Direct in a sense that it is benefiting from all the classic Bluetooth infrastructure that people are now familiar with, like pairing mechanism and Bluetooth profiles that ensure interroperability at application level. But I agree this will not solve the issues you are highlighting. Some improvement of the Bluetooth 3.0+HS could make it, with for instance a clever Wi-Fi channel selection that minimizes the interferences with surrounding AP.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
