WLAN Access Point is ATEX-certified

Paul Boughton
With the new Hirschmann BAT300 FX2, Belden is marketing what is claimed to be the world's first ATEX-certificated WLAN Access Point with support for the new IEEE 802.11n transmission standard. This enables WLAN networks with data rates up to 300Mbit/s to be installed even in hazardous areas rated Ex zone 2. The integrated Mimo (multiple input, multiple output) antenna technology ensures a stable wireless connection. Other features of these Access Points include extensive management, security and quality of service functions, plus layer 3 IP routing.
The BAT300 FX2, which can be used both as an access point and access client, is designed to operate at temperatures in the range -30 to +50 degrees C, and also fulfils all necessary shock-resistance, vibration-resistance and electromagnetic compatibility requirements (EN 50155). The high level of operating security is facilitated by the LAN ports' M12 connections (10/100Base-TX) plus a redundant power supply with two 24V DC and one 48V DC connections supporting power-over-Ethernet communications compliant with IEEE 802.3af.
Belden says the Access Point's wireless module operates either in the 5GHz or 2.4GHz waveband. The fast roaming function facilitates uninterrupted connections while passing from one radio cell to another. The integrated IP router can be used to form up to eight subnetworks, and analogue or DSL modems can be connected for WAN routing or remote maintenance. The network can be managed using web interface, Telnet, TFTP, FTP or SNMP V2 and the redundancy methods Rapid Spanning Tree and VRRP ensure a high level of network availability. The quality-of-service functions, as specified by IEEE 802.11e, facilitate features such as prioritisation of voice or video streams.
The BAT300 FX2 supports all encryption and authentication methods compliant with IEEE 802.11i and 802.1x/EAP as well as WEP, WPA, WPA2, TKIP, AES and LEPS. It also comes with WLAN port filters and protocol filters, a radius server and a firewall with intrusion detection. Rogue AP detection is also available via background scanning and WLAN monitor.
Access Point devices can be installed indoors or out. The dimensions of the robust metal housing are 261 x 189 x 55mm (W x H x D).
Product manager Olaf Schilperoort states: "The new IEEE 802.11n transmission standard facilitates data rates comparable with those of a terrestrial Fast Ethernet network. This enables applications such as HD quality video transmissions, which call for 20Mbit/s per camera. And Belden's launch of the BAT300 FX2 makes it the world's first manufacturer to extend IEEE 802.11n into areas with an Ex zone 2 rating."
