The Mobile INTernet router (MINT for short) is a core element of the Walkstation II Project. Its purpose is to link via a radio resource one or many mobile hosts, the latter are either independant or connected together forming a isolated subnetwork. The MINT has a communication device consisting of an Ethernet Controller and a radio tranceiver, currently working at 2GHz. The RadioNet Driver, a device driver is used control these pieces of hardware. Progress has been slow. Initial work involved exploring the MINT's programming environment (cross-compiler, debugger) and doing some experiments with the MINTs. Next, a dummy RadioNet driver was written to become familiar with programming in the (SunOS) kernel. Then the LANCE driver for the MACH kernel was modified, resulting in the RadioNet driver. This talk will decribe the tools and the current status of the RadioNet driver. / <p>Just as for Markus Oelhafen's thesis, Pascal was an exchange student with EURECOM, so I do not know the credits or even if he was registered at KTH.</p>
