Critical Elements of Industrial-Grade Wireless Devices

 

Industrial operators using commercial-grade wireless devices for mission-critical wireless applications may be getting satisfactory wireless network service, but frequent maintenance and system downtime can add up to a high total cost of ownership. In this paper, we reveal many harmful effects commonly found in industrial environments that can quickly disable a commercial-grade wireless device, and discuss the types of protection an industrial-grade wireless device should provide to ensure continuous wireless network communication...more

Industrial WLAN and WWLAN Guide BookAdvantages of using wireless technologies include boosting data transmission speed, real-time data transmissions, remote equipment monitoring and alerts, flexible installation of remote equipment, and wide coverage areas. In addition, wireless technologies can penetrate areas where cables are unable to reach, saving wiring costs. By adopting wireless technologies, industrial applications are able to benefit from greater versatility.

However, the completeness of data, security of transmission, and reliability of the wireless network are constant concerns as wireless technologies rely completely on the emission of electromagnetic waves through the air. Drawing from over 20 years of experience, Moxa offers users the most reliable industrial networking solutions including Turbo Roaming™ for seamless wireless communication, as well as extended wireless transmission ranges of over 10 km. In addition, our complete selection of products for demanding industrial environments includes wide temperature (-40 to 75°C) models, IP67-rated protection from water and dust, and EN50155 certification for rail traffic applications.

We hope this guidebook will provide you with a more comprehensive understanding of industrial wireless technologies and serve as your most trusted guide to getting un-wired!
