Benefits of Unlicensed Radio

• 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

20

• 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
22

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

23

• 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
