PORTIA radio transceivers provide an extremely high wireless network range. To achieve this, radios use the proprietary SPIDERMESH technology, a cooperative mesh wireless protocol developed by Smartrek Technologies. This protocol provides synchronous communication between the links to mitigate network contention issues. As a result, this strategy allows PORTIA radios to offer a connectivity solution for the most challenging applications.
Each radio can be configured either as a gateway or a node. Gateways control the entire mesh network by coordinating wireless data exchanges. Furthermore, they also act as a bridge between mesh networks and a host such as a computer, tablet, or internet gateway.
The nodes act as repeaters within the linked networks. Data transfer is bidirectional; thus, nodes allow for controlling and/or reading digital/analog external modules, connecting them to the mesh network. Additionally, activating a link in the field only requires the node to be on the same radio frequency channel as the network during deployment. Consequently, this considerably reduces installation complexity as no technical knowledge is required for its use.
