Wireless Nodes

The RoamAD platform employs multi-radio, multi-spectrum wireless nodes comprised of best-of-breed, standards-based components such as Atheros-based radios and Intel XScaleT or x86 motherboards used as the core of the wireless nodes.

RoamAD's platform supports up to four radios per node using any combination of 900MHz, 2.4GHz, 4.9GHz, and 5 GHz for either backhaul or end user access. Backhaul options include point-to-point, point-to-multipoint, multipoint-to-multipoint, mesh, and mobile mesh either in self-forming, self-healing modes, or in RoamAD's infrastructure-mesh mode.

RoamAD has developed a standard hardware assembly design for multi-radio intelligent network nodes. RoamAD's software is required for operation of the nodes.
