Multi-Radio 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 XScale™ 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.

RoamAD's VAR/SIs partners either assemble multi-radio nodes themselves or purchase them pre-assembled from RoamAD OEM Partners who are certified by RoamAD to sell RoamAD Compatible multi-radio nodes. The VAR/SIs then install RoamAD's software on the nodes and supply the completed solution to the customer.

A typical node consists of:

• Embedded motherboard (with 1 or more onboard 10/100baseT Ethernet interfaces).
• 64/128 MB SDRAM.
• 128 MB Compact Flash card.
• CPU (x86 or XScale).
• Four radios and four spectrum bands per node. Any mix of:
  • 900 MHz (900-928 MHz)
  • 2.4GHz (2.400-2.483 GHz)
  • 4.9 GHz (4.940-4.990 GHz)
  • 5 GHz (5.12-5.25, 5.25-5.35, 5.47-5.725 GHz, 5.725-5.825
• Lightning surge protectors (optional).
• Power over Ethernet (PoE) or DC power supply (115/240V 50/60Hz power supply).
• Weather rated outdoor cabinet.
