High power Ethernet radios offer long-distance communication in a mesh network


Phoenix Contact's new high power industrial radios provide secure wireless communication over a long-distance, wireless mesh network of up to 40 radios. The RAD-80211-XD/HP and RAD-80211XD/HP-BUS feature 400 mW (26 dBm) transmit power and 128-bit AES encryption.
A unique auto-bridge mesh mode allows the network to self-form and heal if a radio drops out of the network. This results in an uninterrupted flow of data even if other bridge devices or network segments in the data’s path fail.

Like the other radios in the RAD-80211-XD series, the high power radios also support access point, client and bridge/repeater modes. They conform to standards 802.11b/g and operate in the 2.4 GHz band.
With the radios’ simple, IT-friendly embedded software, any network PC with a web browser can configure the devices. Built-in RS-232 and RS-422/485 device servers allow the integration of serial devices onto the wireless Ethernet network.

With the RAD-80211-XD/HP-BUS radio, up to 64 digital, analog and pulse I/O points can be interfaced directly to the radio by connecting the RAD-Line expandable I/O modules.  The I/O modules can be addressed via Modbus TCP or legacy serial Modbus RTU over the 802.11 network. This provides a standard solution for facilities undergoing incremental upgrades. Multiple wireless communications streams allow simultaneous Ethernet, I/O control, and serial ASCII device communications – all from a single radio without external gateways or additional serial wireless converters.

Both the RAD-80211-XD/HP and RAD-80211-XD/HP-BUS units are approved for use in Class I, Division 2 hazardous locations.
