wireless transceivers offer store-and-forward capability
Cirronet Inc. has added store-and-forward capability to its popular WIT910
and WIT2450 OEM modules and HopNet HN-291 and HN-250 standalone modems.
This new capability eliminates the need for expensive repeaters when
transmitting around barriers, with the added benefits of expanding network
reach and increasing the number of nodes that can communicate with a single
base station.
Wireless transceivers are typically networked in star topologies, with
a base station communicating directly with each node. When barriers such
as large storage tanks or steep hills exist within the network area, repeaters
function as intermediaries, forwarding data between the base station and
impeded nodes.
With the new Cirronet store-and-forward capability, any node with a clear
path to both the base station and another node can assume the role of
repeater, at far lower cost.
This capability extends network reach; the 20-mile range of the 900 MHz
WIT910 and HN-291, and the seven-mile range of the 2.4 GHz WIT2450 and
HN-250, can be multiplied by the number of units employed in a store-and-forward
link.
Latency introduced by this action is negligible for all but the most
time-sensitive control applications, and occurs during only the first
store-and-forward action.
Also increased is the number of devices that can communicate with a single
base station, from the previous maximum of 62 to a new maximum of 255.
