The AirJaldi Mesh Router (AJMR) is built around a SBCs (Single Board Computers) which we extract from low-cost popular WiFi devices such as Linksys WRT54G . Most of the SBCs used, utilize a 200mhz MIPS CPU with 4Mb of Flash memory and 16Mb of RAM. However, we also use some lower-scale units and recently also developed more powerful units. The Netgear WGT634U appears to be most suitable for our application but it was recently discontinued. This small SBC draws less power then its bulkier cousins, features a MiniPCI slot for radio card, hosting a great Atheros b/g radio, double the flash and ram of the WRT54G and maybe the greatest feature of all is a USB2.0 port.
