The
SecureMesh™ Gateway
is a network takeout point and root node of the SecureMesh WAN. Each
Gateway acts as a SecureMesh WAN “base station” routing all its associated SecureMesh WAN traffic to/from
the utility head end.
The Gateway uses a dynamically switched high-gain antenna array of eight separate 45° beams to
provide omni-directional coverage. Patented synchronous dynamic beam-switching technology then
coordinates use of each antenna beam to communicate with other WAN nodes.
Each SecureMesh Gateway and its associated WAN subnetwork provide an overall air data rate up to 54 Mbps
and information throughput of ~15-20 Mbps, where this capacity is dynamically shared (or explicitly allocated)
to support the network’s intended applications, such as AMI and HAN traffic backhaul, DA, video surveillance,
or, typically, a mix of these and other applications. Given the low bandwidth requirements of Neighborhood
Area Network (NAN) meters and other devices, tens of thousands of NAN nodes are generally supported by
each Gateway in addition to the 100s of WAN client devices that can be attached to its associated WAN
nodes.
Adding more Gateways to a SecureMesh WAN deployment enhances network reliability and, more importantly,
modularly increases the network’s total capacity. The overall SecureMesh WAN capacity is then defined by
the total number of Gateways times the throughput through each Gateway.
