| The SkyGateway - Carrier-Class Base Station |
The SkyGateway™ is a carrier-class base station that provides the traditional functionality of connecting a wireless network with the Internet. The similarity with traditional bases stations, however, ends there. Unlike broadband point-to-multipoint base stations, the SkyGateway provides true mesh networking, multiple hops to subscriber nodes, redundancy, and scalable network capacity by means of SkyPilot’s innovative 8-antenna array, high-power radio technology, and sophisticated link management capabilities.
The reason that the SkyGateway offers so much more functionality than traditional base stations is through the use of multiple point-to-point links within a wireless mesh network. This architecture provides redundant routes within the mesh to provide self-healing capabilities as well as allowing several hops between the subscribers and the base station. When coupled with its long range features and the non-line of sight (NLOS) capabilities of OFDM modulation, the network can be extended to reach a broad base of subscribers.
Another benefi t of this mesh architecture is the ability to connect multiple base stations to the same network. This enables multiple, redundant paths to the Internet and SkyPilot’s sophisticated routing algorithm ensures both best-path optimization and failover capabilities in case of changes or failures in the wireless network. And with each SkyGateway providing up to 20 Mbps of network capacity through an integrated 10/100 Base-T Ethernet connection, the network can scale easily and gracefully to meet the capacity needs of growing subscriber base. |

| Key Benefits |
 |
Overcomes limitations with point-to-multipoint base stations by providing true mesh networking, multiple hops to subscriber nodes, redundancy, and scalable network capacity. |
 |
5 GHz backhaul combines benefi ts of mesh networking and point-to-point links |
|
| - |
Mesh networking: 360° coverage, multiple links with optimized routing and link redundancy, load balancing capabilities |
| - |
Point-to-point links: high-power (up to 28.2 W/44.5 dBm EIRP) focused beams and eight 18 dBi antennas
improve penetration and extend range up to 10 miles/16 km |
|
 |
SkyGateways work in conjunction with each other to provide scalability and redundancy |
|
| - |
Each base station provides up to 20 Mbps of Internet capacity, so network capacity can be scaled easily to address increased performance needs |
| - |
Increases in subscriber density can be addressed easily by adding base stations, which segments subscriber traffic through optimized routing paths |
| - |
Multiple base stations provides redundant Internet paths with failover capability |
