How Well Does It Work

• How Well Does It WorkDepends On Needs
• If Only Need Data LoggingWorks Great
• Data Can Come In Late And No Problem
• Many ProvidersVery Effective And Cost Efficient
• If Need Reliable AlarmsOnly A Few Providers
• New IndustryExperience Counts
• If Need Reliable Realtime DataOne Provider
• Realtime Is Hard To Do Reliably
• The Best Average End To End Up Time Of 99.7

Why Consider Managed Cellular In A Hybrid System

• Why Data Cellular SCADA
• Usability
• Very Simple Flexible
• Reliability
• End To End Uptime Can Be 99.7
• Survivability
• Proven In Hurricanes And Severe Storms
• Security
• Meets AWWA Homeland Security Standards

9
Why Consider Managed Cellular

• Some Of How It Can Help
• Data Cellular SCADA
• From Box To Running In A Morning
• Information To You AnywhereSecurely
• Very Simple To Install, Operate Service
• Fits Easily Into Existing SCADA Systems
• Use It For
• Stand Alone Sites Where This Is All You Need
• Backup to Existing SCADA Sites
• Fill-In For Hard To Reach Or Lower Priority
  Sites

How Much Does It Cost

• How Much Does It Cost
• Systems Have Two Parts
• A Complete RTU And An Annual Service Fee Per RTU
• Some Have Flat Rate Fees, Some Charge Over Use
• Depends If Need Daily, Hourly Or Realtime
• Hourly RTUs 1,200 Range 300 - 350 Annual
  Fee
  
• Realtime RTUs 2,000 Range 550 Annual Fee
• Costs vs Dialers or Traditional SCADA

11
The Best News Mix and Match

• Dont Give Up One For The Other
• All Can Co-exist On The Same System
• Use National Data Networks
• High cost sites
• Poor performance sites
• Redundancy
• Outlying sites
• New projects
• Upgrades and replacements
