On his blog, Jon Phillips writes
about free/libre hardware that implements the 802.15.4 wireless personal area network
protocol. The devices come from Qi Hardware
; one fits into the Micro-SD slot of a Ben Nanonote
, the other fits into a standard USB slot. This is all part of the Ben WPAN
project, which describes itself as follows: "Ben WPAN is a project to create an innovative patent-free wireless personal area network (WPAN) that is copyleft hardware. The primary protocol is 6LoWPAN, pronounced "SLoWPAN". The project lead is Werner Almesberger and it involves using the UBB, new testing software, and the Ben Nanonote to produce a next generation wireless personal area network.
