Wireless Automation Level Network

Solutions

Figure 1. Wireless Automation Level Network Solutions.

Description

Ethernet field panels, and workstations, that

communicate on the APOGEE

Automation Level

Network (ALN) can connect to the ALN via wireless

communication links, versus hard-wired network

cabling. The Ethernet field panels are compatible with

the IEEE 802.11 (Wi-Fi) wireless Ethernet radio

standard, and thus, able to utilize those types of radio

transceivers to establish wireless links.

A single panel, an entire ALN, or any configuration in

between can be connected wirelessly depending on

the project and the difficulty in using traditional hard-

wired cabling.

To implement a wireless ALN connection, two 802.11

radios are used between the field panel and the rest of

the ALN. One radio, an Ethernet bridge, is connected

to the field panel. The Ethernet bridge enables

wireless communication for the panel. Another radio,

an access point, is mounted remotely. The field panel

communicates through the Ethernet bridge with the

access point, and then, the access point routes the

panel’s messages to other ALN devices either

wirelessly or across a hard-wired network.

• Start up and commission the ALN prior to the installation of a hard-wired corporate Ethernet network. • Support wireless connections to the ALN with wireless enabled computers. Benefits • Eliminate difficult and long cabling installations that may be disruptive to a facility and the occupants. • Eliminate reliance on the corporate Ethernet network, without having to run additional network cabling. • Eliminate the need to trench between buildings.
