Wireless Field Level Network (WFLN)

Figure 1. Wireless Field Level Network.

Description

The Wireless Field Level Network (WFLN) is a Field

Level Network (FLN) that communicates via radio

frequency links instead of a hard-wired

communications network (Figure 1). The WFLN utilizes

wireless mesh technology to form a wireless mesh

network.

A wireless mesh network consists of a collection of

nodes that communicate to each other via wireless

links that do not need to be routed through a central

node.

A grid-like topology enables the signal to hop among

different paths in order to circumvent obstructions as it

seeks and ultimately finds its target device. These

redundant communication paths enable a very high

level of reliability. Because multiple signal paths exist,

the network can adjust to potential communication

link disruptions due to changes in the building

environment.

The self-forming, self-healing nature of the mesh network eliminates the need for maintenance as the environment changes. To implement the WFLN, a Field Level Network Transceiver (FLNX) is mounted at the FLN device and a Field Panel Transceiver (FPX) is mounted at the field panel. Both must be powered by 24 Vac. The transceiver antenna can be mounted either directly or remotely. In cases where the radio transceiver is mounted in a metal enclosure, the remote mount antenna would be used.
