2. Wireless In Water/Wastewater Water Distribution Wastewater Systems Irrigation

3. Wireless In Water/Wastewater Unique Challenges and Considerations Greater Distances City or County Coverage Difficult Terrain Trees, Hills, Valleys, Buildings Impractical to Cable

4. History of Wireless Common Licensed Telemetry Frequencies historically used in the Water/Wastewater market  72 to 76 MHz  150 to 174 MHz  400 to 420 MHz U.S.A. Federal frequency Canada civilian frequency  450 to 470 MHz  4.9 GHz

5. Water/Wastewater opportunities

6. The Federal Communications Commission (FCC) mandated that by January 1, 2013, all licensees and users of radio systems operating in the VHF 150 – 174 MHz and the UHF 450 – 512 MHz portions of the of the radio spectrum, convert their systems and radios so that they are operating on 12.5 kHz rather than the current wideband 25 kHz channels. This mandate has been put into place to bring about spectrum efficiency and as a result, to create additional channels to accommodate the demand of public safety and local government users FCC Narrowbanding Mandate

7. Legacy 25kHz Channels Narrowband 12.5kHz Channels (1/1/13) Future Narrowband 6.25 kHz Channels (TBD)

8. Narrowband Challenges World of Legacy Hardware o Many of the legacy wireless networks installed to utilize the VHF & UHF frequency bands for Water/Wastewater applications are “wideband” and cannot be adjusted to meet the new mandate

9. Narrowband Challenges Manufacturers can no longer sell wideband equipment. Replacement units are not compatible!

10. Narrowband Challenges Countless Municipalities are not compliant and many are still unaware of the reality of this mandate!! o Under the current FCC ruling, if you are licensee, operate, or use a system in the affected portion of the spectrum, you must comply with this FCC mandate o All Licensed VHF 150-174 MHz & UHF 450-470 MHz must relicense and ensure equipment is operating in 12.5kHz channels o Estimated 200-300 are not still not in compliance o Misconception of relicensing vs Hardware compliance

11. Narrowband Challenges Why should they care? $16,000 fines Per Day !!! $$$ Loss of License Loss of Data!!! 10110101100011010101010

12. Narrowband Challenges Data Rates Wideband = 19,200 kbps Narrowband = 9,600 kbps Legacy Networks - DF1 Serial Communications = Legacy communications at half the speed!!

13. So Now What? ?

14. Evolving Wireless Technology Wireless Has Come a Very Long Way o Evolution has occurred in all technology – wireless included!  More efficient FSK modulation = increased speeds that “fit” in narrowband mask  Spread Spectrum allows higher Data-Rates and offers license-free operation  QAM Modulation – phase shifting produces incredible data rates in the Narrowband channels = 64.8 Kbps * Allows EthernetIP communications and true networking infrastructure while utilizing VHF & UHF Frequencies

15. Water/Wastewater Opportunities Rockwell Opportunities Migrate Legacy DF1 Networks o Legacy hardware o Serial communications o *9,600 kbps data rate after narrowbanding mandate DF1 Networks Legacy Ethernet/IP Integrated networks Connected Enterprise Remote Asset Monitoring

16. Evolving Wireless Technology The benefits of the Connected Enterprise do not end at the plant wall or at the end of a data cable. Access to critical information from remote assets is just as important, perhaps even more important……

17. Water/Wastewater Opportunities Rockwell Opportunities Preserve Valued Customer base Previous wireless Encompass Partner relationship with MDS MDS = GE!!! Don’t let your existing customers migrate to GE because the MDS wireless system requires an upgrade to meet narrowbanding mandate

18. One size does not fit all …..the right tool dictates a successful network roll out

19. Application Sets the Standard o No one frequency or wireless standard will solve all applications o Every frequency and standard has it’s place o Correct selection for application is key

22. Physical Environment demands Step 2

23. Appropriate Technology

24. Designing Wireless Networks Highest consideration in wireless Critical in wireless design Reliability Mesh Networking Multiple Modes of Operation Network Monitoring Necessary Features Multiple paths for data transmission Automatic system recovery “Mesh Networking” Redundant Links

25. Reliability Using MESH Technology Redundant Repeater Routes o “Self Healing Networks” o Alternate Communication Paths Industrial MESH Network o Different than Commercial Mesh Networking o Manually configured o Configurable Priority Routing
