 What Is Spread Spectrum Technology ?

n DataHopper Series (SS Radios) DataHopper 115 S/EI and DataHopper 276 S/EI. Model number indicates radio bandwidth, i. e. 115 Kbps, 276 Kbps, etc. S indicates Serial Interface; EI for Ethernet interface.  DataHopper 550 S/EI (Future)  Datavision Series (Video Cameras) Datavision 2100, Datavision 3000

n 900 MHz Spread Spectrum serial and Ethernet radio n High bandwidth n Long Distance ( up to 60 miles LOS) n Supports point to point and point to multipoint n Powerful 1-watt transceiver FRONTBACK

Point to PointPoint to Multipoint Network Diagrams

n Link an unlimited number repeaters n Connect up to 4 masters n 64 different user-selectable pseudo-random hopping patterns n User-configurable encryption key for enhanced security n Built in data error detection n Remote network configuration and diagnostics over the airwaves FRONTBACK

FrontBack n Onboard I/O – 2DI, 2DO, 1AI, 1AO n Both Modbus master and Modbus Slave Protocol n Control remote stations without cost of extra hardware n Can cascade multiple Ethernet and serial devices

FrontBack n 900 MHz spread spectrum Ethernet and Serial Radio n Same Features as DataHopper 115 S/EI at More than twice the throughput (276 kbps) n Simultaneously handles both SCADA data and video surveillance streams

REMOTE RTU SENDS DATA TO REMOTE RADIO VIA ETHERNET OR SERIAL RTUREMOTE RADIO

MASTER RADIO REMOTE RADIO TRANSMITS ENCRYPTED RTU DATA TO MASTER RADIO

A² T940 Master RTU Master Radio MASTER RADIO SENDS UNENCRYPTED DATA TO MASTER RTU

 Increased security for any business  No more expensive lease line charges from the phone company  License free - Requires no bothersome FCC license application  Fast inexpensive alternative to installing fiber optics  Scalable architecture  Onboard I/O with Modbus protocol requires no PLC or RTU at remote sites with limited I/O i.e., water tanks Benefits of Unlicensed Radio

 Maintain your own private network - your not married to the phone company  No outside fees or maintenance costs

MASTER RADIO SENDS DATA TO MASTER CPU MASTER CPU STORES CAMERA IMAGES ON HARD DRIVE

 RF Propagation Studies  SCADA Setup and Installation A² Integration with the DataHopper 900 series

 To ensure reliable communications for data  Based on topographical analysis, foliage depth, and field tested path RSSI levels  Analyze coverage patterns  Determine radio configurations required  Check for co-channel and out-of-band interference
