ReFLEX™ Wireless Technology Wireless Data Before Wireless Data was Cool
Needs – Acquiring Information
• Meter Reading
• Site Security
• Load Shedding
Solutions
• People – Eyes On
• Wired – Modems, LANS
• Wireless – Telemetry, SCADA, WAN
Monitoring and Control
Wireless Network Proliferation
• Reliability• Robustness• Coverage• Hardware Cost - Initial Capital Cost• Airtime Cost – Ongoing Cost
• Licensed – Cost per device per month• Un-licensed – Cost of maintaining system
• Data Integration Cost
IT IS ABOUT MONEY
Wireless Considerations
Key Issues In Fielding Telemetry (Wireless) Systems
Why ReFLEX™
Reliability-Engineered for Data
• FLEX, one way paging, invented by Motorola 35 years ago • system engineered for data, not voice
• ReFLEX™, two way paging, developed in the 1990s• two way paging connected remote devices
• Device to device • telemetry module introduced in 1999 connecting remote
devices and the Internet• Provides for assured messaging
• If it can be delivered, it will be delivered• Data error correction• Messages stored in queue for up to 72 hours
• If message not delivered, you will know• No competition from other protocols on a ReFLEX™ network
RobustExcellent in Building Penetration
• ReFLEX™ networks “simulcast” from towers to the ReFLEX™ devices
• Each device is serviced by multiple sites transmitting in unison (75 – 500 watt transmitters)
• Robust• ReFLEX™ networks employ
“macro-diversity” on the path from the devices to the network
• Many sites hear the transmission of a single device
• Approximately 1 watt transmission
• Extremely sensitive network equipment

Hardware Cost
Initial Capital Cost
Hardware
•Multiple deployed applications
•Several manufacturers – competition
•Existing and deployed networks
•Web-based automated meter reading and load shedding, site security devices currently available
Airtime Cost
Ongoing Cost
•AirtimeAirtime
•Competition in the technology and between carriers Competition in the technology and between carriers keeps data prices stay lowkeeps data prices stay low
•Recurrent airtime prices for as little as $1.00 per Recurrent airtime prices for as little as $1.00 per month per devicemonth per device
•quantity airtime based upon number of devices in quantity airtime based upon number of devices in serviceservice
•Typical costs for low volume, low airtime usage Typical costs for low volume, low airtime usage accounts is $2 – 3 monthlyaccounts is $2 – 3 monthly
Data Integration Cost
• SMTP - Simple Mail Transfer Protocol • Out of the box, every ReFLEX™ unit has an
email address.• Simple message routing using well known
standard protocol
• WCTP - Wireless Communications Transfer Protocol • XML based for easy integration• Free Support from Wireless Carriers• Enterprise class connections for FREE!• Open protocol – www.wctp.org
Wireless Comparisons
In Review
• ReFLEX™ is:• Built and engineered for two-way
data• Reliable and robust• Built for in and out of building use• Wireless coverage where 95% of
the population are located• Lowest cost public wireless
network from an airtime and hardware cost perspective
ReFLEX™
Since the Dawn of Remote Monitoring and Control
