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.

Tropospheric Ducting

Seasonal weather patterns can create channels for RF propagation, bringing remote but very strong interference from hundreds of miles away.

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.
