ISCO has successfully completed the first over-the-air testing of Interference Management and Cancellation (IMC) technology embedded within an O-RAN Distributed Unit (DU).
ISCO conducted testing with a national research laboratory, utilizing Open RAN equipment over a 5G network. The goal was to demonstrate the ability to deliver resilience measures and hardened 5G infrastructure against jamming and interference.
During testing, jammer-induced interference degraded 5G network throughput to approximately 20% of the baseline performance. Upon activation of ISCO’s Interference Management and Cancellation (IMC) technology, the system successfully detected and mitigated the jamming signal. As a result, network throughput was restored to as much as 80% of the baseline, demonstrating the effectiveness of ISCO IMC in maintaining operational performance under hostile RF conditions.
Embedding the software in Open RAN equipment solves the problem of interference and jammers network-wide without requiring the cost and complexity of extra equipment. Having the interference and jammer cancellation software in the Open RAN DU is crucial to ensuring 5G networks that support critical infrastructure and public safety, defense and military applications are protected.
