Wireless Technology Evolution Just as Ethernet has evolved from an office network, to a network that could be applied in some industrial applications, to a network suitable for real-time plant floor control today… Evolution of wired Ethernet for control applications Past Today Future 10M 100M 1000M Half-duplex Full-duplex Hubs Switches Enhanced Features …so too will wireless technology evolve for easily deployable, real-time, plant floor control applications. Wireless for real-time applications is where Ethernet for control applications were 3-5 years ago. Commercial needs (i.e. Voice over IP) will help drive solutions that can be leveraged by EtherNet/IP.

Recommendations Understand where wireless is appropriate –No fully wireless factory (still need power cables) - still many excellent applications –Mostly for information, limited control usage possible today – more in the future ??? Understand where wireless is beneficial –More efficient workflow Access to multiple information sources without travel or second party involvement Information entry for paperwork reduction, auditing, and alert –Legacy retrofit for automatic information gathering Maintenance, temporary or experimental deployment –Cable replacement for festoon or great distance Determine IT involvement –Security, LAN re-use, maintenance Perform a site survey Get a partner with industrial wireless packaging and installation experience
