11. Wireless Ethernet Applications

12. Wireless I/O (Ethernet/IP)
Processor-less I/O (Implicit messaging)
Designed for high speed, dedicated Ethernet segments
Uses UDP multi-cast packets
Wireless has limited applications
Timeout, latency concerns
Non-deterministic applications only
Not recommended for safety related I/O
Wireless a good solution for:
SCADA type functions
Non-critical remote I/O

13. Wireless Ethernet Applications

14. Wireless Design Guidelines
RF site survey
Line-of-sight?
Other existing RF systems? What frequencies?
Antenna placement
Theoretical (software) survey

15. RF Site Surveys (Theoretical)
