1. Mini-GPS2 and Canopy GPS Synchronization

2. Mini-GPS2 Takes advantage of the timing port
Timing Over the Power Port has known issues
M12+ GPS Receiver

simultaneously

3. Mini-GPS2 Features Outdoor rated NEMA4 enclosure for outdoor mounting
Operates on 110/220 VAC or VDC
Allows use of any custom networking device, including VLAN and Layer 3 options
No firmware to fail or to continuously update
Includes Timing 3000 GPS
antenna and mounting
hardware

4. GPS Synchronization and the Relationship to Canopy RF

5. Time Division Duplexing (TDD)
GPS is used to enable Time Division Duplexing
Method Canopy uses for data transmission
Effective method of radio transmission
Synchronizes the RF transmission and reception
Radios only transmits or receive at once never both
GPS is a worldwide clock for collective synchronization
Does not turn on and off the RF transmitter

6. GPS and Canopy Spectrum Analysis
TDD is highly favorable because of the amount of the frequency spectrum that each Canopy unit covers. A full Canopy RF signal covers almost 40MHz in the 2.4GHz, 5.2GHz, and 5.7GHz frequency bands.

7. GPS and Canopy Spectrum Analysis
The amount of spectrum used is also important for frequency layout throughout a Canopy network. GPS will help to insure all radios are in unison.

8. Canopy GPS Synchronization
GPS controls RF transmission cycle by TDD
GPS does not control the RF signal power level
Without a sync (GPS or Generating Sync an AP/BH will not transmit at all
GPS is required at all locations where a Canopy radio is in range of another Canopy radio of the same frequency band. Including remotely installed APs.
Problems with a conflicting synchronization are seen in data packet loss (ping times, etc)
