About Interference and Motorola Canopy

What`s Interference ?
Interference occurs when one radio signal disrupts the transmission of another signal.
C/I Ratio :
- Carrier to Interference Ratio
- Describes How Strong the Desired Signal (the Carrier) is Relative to unwanted signals (interference)
Sources Of Interference:
Self Interference
(emanates from a network under ur control)
External Interference
(opposing Signal Coming From A Network, Device or other source not under ur control)
Canopy Virtually Ignores External Interference
- Canopy was optimized to ignore external interference
- every radio is factory tested to meet throughput at 3db C/I
- Canopy nominal C/I performance is ~2 dB
- Competitions C/I requirements are 8db - 25 db
Canopy Does Not Create Destructive Self Interference
- Canopy avoids self interference through precise GPS synchronization
- Cluster Management Module has GPS Receiver to deliver exact synchronization signals to APs and BHs
- AP Cluster can be put where capacitu and/or coverage is needed
How Canopy Stacks Up
- A system with 8-9 dB C?I can not reuse same frequency in adjacent sites.
- In The Canopy System, Nearby Users & Nearby Cells Do Not Interact
