Interference Management & Cancellation

Build Resilient 5G Networks with IMC

Wireless interference disrupts the operation of mobile networks, sometimes to the point where the cell phones lose signal and the cell site is rendered inoperable. Interference events and effects can come from an array of sources:

ISCO's Interference Management and Cancellation (IMC) is a comprehensive system comprised of four elements designed to protect the wireless network.

1. Spectral Level Monitoring & Detection

7 x 24, 365 days a year, IMC software is continuously monitoring the wireless carrier at the spectral level for the purpose of detecting RF impairments and anomalies that will degrade the network.

2. Autonomous Mitigation

The IMC software takes actions by initiating cancellation techniques without dependence on external triggers.

3. Notification & Logging

The IMC software within the RU, DU or RIC will pass information not previously available about the detected interference conditions to RAN elements (the RU, DU and RIC). This information can be used for further RAN optimization and performance improvement. These improvements can include avoidance techniques, null forming, scheduler changes, and precise PRB blanking as examples.

4. Classification & Spectral Recording for Continuous Improvement

IMC will record and classify spectral conditions as they are experienced. The information and intelligence captured is used to profile the interferer for the purpose of determining whether new cancellation and avoidance algorithms can be developed to address it.
