Expert Tips for Optimizing Industrial Wireless Networks


Compared with its popularity in everyday commercial environments, Wi-Fi has been slow to gain a foothold in industrial M2M applications. One of the main reasons that industrial customers are reluctant to move from wired to wireless is the problems associated with stability. Wireless transmission is NOT as reliable as wired transmission. However, by following certain best practices it is possible to set up a wireless network that will provide the level of reliability needed for M2M communication applications. In this whitepaper, we present eight expert tips that you can follow to optimize your wireless networks for industrial application environments...more
