PRLog - Jan. 28, 2011 - WLAN solutions have become an excellent choice for train-to-ground communication networks because they offer wider coverage, higher throughput, and more bandwidth. The industrial-grade AWK series to be compliant with IEEE 802.11a/b/g/n, and in particular to meet higher EN50155 and EN50121-1/4 standards to withstand harsh rail environments.

The New generation AWK-6222 and AWK-5222 feature dual independent RF modules with 2.4 or 5 GHz dual-band operation to enhance redundancy and frequency range. They can be configured in AP-client connection mode or redundant wireless connection mode to provide application flexibility. This reliable wireless LAN link gives the railway industry a reliable and real-time data communications solution for flexible deployment on moving trains to maximize overall passenger safety. The AWK-6222 outdoor dual-RF wireless AP/Bridge/Client provides a flexible solution for industrial applications in a critical environment. The AWK-6222 is rated to operate at temperatures ranging from -40 to 75°C, and its dust-tight and weatherproof design is IP68-rated, allowing you to extend existing wired networks to outdoor locations. With two independent RF modules, the AWK-6222 supports a greater variety of wireless configurations and applications. It can also increase the reliability of an entire wireless network by enabling redundant wireless connections. The AWK-6222 has two redundant DC power inputs to increase the reliability of the power supply, and can be powered via PoE..

The new AWK-3131 and AWK-4131 devices are both 3-in-1 industrial wireless AP/Bridge/Client products that will support the 802.11n standard with a net data throughput of up to 120 Mbps, and wireless communications in the 40 GHz spectrum. This 802.11n solution not only extends the wireless coverage range, but also achieves real-time data transmissions for critical tasks such as VoIP communications, video streaming, and high density data transfer in the rail industry. the AWK-3121 Access-Point/Bridge/Client. The AWK-3121 is rated to operate at temperatures ranging from 0 to 60°C for standard models and -40 to 75°C for wide temperature models, and is rugged enough for any harsh industrial environment. Installation is easy, with either DIN-Rail mounting or distribution boxes. The DIN-Rail mounting capability, wide operating temperature range, and IP30 housing with LED indicators make the AWK-3121 a convenient yet reliable solution for any industrial wireless application. In order to deliver reliable real-time data transmission and passenger safety these provides 50 ms Turbo Roaming and 802.11n solutions to deliver highly available rail infrastructure.

Railway wireless networks must offer mobility, deployment flexibility, and security for expansion and migration, and be tough enough to provide continuous, reliable, long-standing operations between the ground and the moving train. With increased reliability and bandwidth, WLAN is also tapped to support on-board video surveillance, passenger-related information systems, and train control. These networks allow rail operators to share real-time information between trains, the operating control center (OCC), and stations to provide immediate status updates and emergency controls
