The problem
Uplink interference degrades every user on the affected cells, and its source can be anything from a faulty connector to a device outside the network. Finding it means field teams with spectrum analysers.
Without knowing which type of interference it is, teams often send the wrong action to the wrong place.
How it works
Confirm the fix
After the intervention, the agent measures uplink noise on the affected cells and confirms the interference is gone.
Which cells in the south region have external interference this week, where is the source, and how many customers does it affect?
The interference sources classified by type, located on the map and ranked by customers affected, with the field action for each.
Frequently asked questions
Which types of interference does it classify?
External interference, passive intermodulation (PIM) and atmospheric ducting, each with the action that fits it.
Which vendors and technologies does it support?
All major vendors and technologies, from 2G to 5G. The data from every vendor in your network is brought into one model before the agents work on it.
Does the platform change anything on the network by itself?
No. The agents detect, locate and recommend. Your engineers decide, and changes go through your own systems.
Where has it been used?
With Telefónica, where the mean time to repair interference dropped by 75%.
“O2 climbed one position in independent rankings after deploying our anomaly detection and root cause analysis engines.”
