Teeny tiny meshcube
4G Systems has released an interesting little product called the MeshCube (and it's enterprise cousin, the 4G Access Cube). As one might expect, it is a hardware platform that enables the creation of mesh networks quickly and easily in areas without infrastructure, either as a temporary (disaster areas) or permanent (libraries) wireless backbone. It supports 802.11a, b and g, power-over-Ethernet, loads of built-in security and a range of 120 meters inside and 350 outside. It's also really small (74 x 53 x 76 mm) and has no moving parts.
