Belden Australia offers three new BAT controllers from its Hirschmann™ product range to ensure fast data communications and optimum network availability.
The Hirschmann BAT controllers are designed for centralised management and monitoring of large-scale wireless LAN networks.
With the launch of its new BAT WLC controller, Belden is extending its proven Hirschmann™ BAT program to include a new class of devices for WLAN data transmission in an industrial environment.
This enables even large-scale wireless networks with up to a hundred access points to be configured and managed from a central location.
Hirschmann BAT controllers (WLC25, WLC50 and WLC100) are designed for use in switch cabinets and can be used to centrally configure and manage 25, 50 or 100 WLAN access points respectively.
As these controllers are fully compatible to all Hirschmann™ access points in the BAT series, existing BAT systems do not need to be replaced.
These controllers possess four freely configurable Gigabit Ethernet ports plus one USB 2.0 as well as one serial interface and communicate with the access points via a CAPWAP tunnel. They also support all standard Ethernet LAN and WAN protocols.
When the WLAN network is set up the controller automatically finds all the available access points, checks their firmware and configures the equipment appropriately for the installed application.
During normal operation the controller provides the administrator with all the necessary network information. In the event that an access point fails, the controller immediately recognises which device should replace it and automatically integrates it into the network.
With their integrated firewall and VPN Gateway function, these controllers can also be used as a security instance between LAN and WLAN or to link a number of wireless networks over large distances.
New Hirschmann BAT controllers also feature extensive management and security functions, IP routing, fast roaming, support for IEEE 802.11n transmission standards, automatic frequency management as well as a variety of redundancy and backup mechanisms, ensuring fast data communications and high network availability.
Adam Callender, Belden regional manager Australia/NZ, said more and more WLAN applications are being used in the field of automation.
"The new IEEE 802.11n standard enables data rates of up to 300 Mbit/s while simultaneously extending the range and stability of wireless transmissions.
"WLAN controllers are disproportionately expensive for small-scale wireless networks, which still need independent industrial standard access points. But where 25 or more access points are used, the investment will always pay off because it enables the administrator to manage and monitor the network from a centralised location."
