At WiMax World, Motorola displayed the USBw 100, a WiMax USB adapter. The thumb-drive-sized devices come in three versions to connect to WiMax networks in each of the three bands for global use -- 2.3, 2.5 and 3.5 GHz. The Motorola USBw 100 plugs directly into laptops to offer mobile and nomadic wireless broadband connectivity both indoors and out.
