Mesh OLPC Testbed
Mesh OLPC Testbed
In OLPC's Cambridge lab there is a set of XO laptops dedicated to testing the mesh network. Currently there are 25 laptops and a school server in this testbed. In addition to their mesh network interface, all the laptops are connected to the Internet via a USB ethernet adapter. You can do things like reloading the driver/firmware of the wireless interface, scanning/associating to access points, etc.
We ask that you not establish additional mesh portal points (MPPs) without discussing it first with us. Send mail to wad at laptop dot org or mbletsas at laptop dot org.
