Interference Management and Cancellation
Ensuring Resilient Communications for 5G networks
ISCO provides software and FPGA-ready code for 5G RU/DUs to combat interference.
Protect your mission-critical 5G network against jammers, PIM, wideband, narrowband, and other interference.
ISCO’s Interference Management and Cancellation (IMC) solution automatically detects the type of interference, applies mitigation techniques to cancel the interfering signal, notifies the operator, and records the spectral signature for offline analysis.
Our software and algorithms are deployed in the 4G & 5G RAN, and can be implemented directly in OpenRAN RU or DU equipment.
Highlights
In defense of private 5G networks
Organizations like the military and first responders are deploying their own, private (non-carrier) 5G networks. They require the most robust defensive countermeasures against attacks.
Protection from jammers
Guards, high walls, and barbed wire may confine inmates, but not RF signals. At a prison close to the US border, Mexican authorities used a jammer to block cell phone usage by inmates - which severely degraded the networks on the American side.
Licensing IMC for Open RAN
Ensuring the resilience of cyber and physical infrastructure is increasingly important. OpenRAN provides the framework for incorporating our value-added functionality into O-RAN elements such as the RU and DU.
Cancelling 20dB of interference
This spectral time graph shows the telltale signature of in-band, narrowband interference. The bright line in the center indicates a much higher power level at one specific frequency, and is constant over time.
Sources of interference can be characterized by their RF fingerprint. ISCO's IMC solution matches the signal's RF fingerprint against a database of known fingerprints, and activates the relevant algorithms to nullify the interference.
The graph below illustrates a case where a 1 MHz interference source was detected and removed from the base station uplink signal. In this case, over 20dB of interference cancellation was achieved, resulting in a return to normal performance for the sector.
Interference Use Cases
Jammers
Jammers are easy to buy or make, and have increasingly been used by criminals in robberies and burglaries. High-powered jammers can take out an entire cell site.
PIM
Passive Intermodulation (PIM) interference is created by downlink signals in two or more frequency bands that mix and reflect back into the uplink. Despite good cell site hygiene, many sites remain impacted.
DTV towers
Ensuring the resilience of cyber and physical infrastructure is increasingly important. OpenRAN provides the framework for incorporating our value-added functionality into the O-RU or O-DU.
