We are the wireless interference experts

 Let's Talk

All wireless networks are affected by RF interference which can cause network performance to degrade and even stop working as planned.  Interference can be unintentional or intentional, like a jammer that has the specific purpose of disrupting communications.  When a network is part of mission-critical infrastructure supporting public safety or other essential functions, it’s imperative the network includes the ability to react immediately to interference and jammers.  This technology is available from ISCO and can be accomplished in both Open RAN networks and traditional RANs.

ISCO solutions improve mobile network performance by automatically removing many types of interference.

Our software applications condition the RF link between the base station and the subscriber device to remove interference and improve signal quality. With tens of thousands of deployments under our belt, our products and solutions are proven to improve throughput, increase network accessibility and deliver more capacity.

ISCO’s patented, adaptive algorithms automatically identifies interference, detects the type of interference (PIM, narrowband, wideband) and applies digital signal processing (DSP) techniques to eliminate interference and noise.

PIM caused by Physical, Environmental and Spectrum Conditions

Signals from multiple transmitters can interact and create Passive Intermodulation (PIM) that degrades the uplink signal, coverage and overall network performance. The PIM problem is growing as networks evolve with more frequency bands being deployed. Our solution removes PIM, regardless of its source.

Taking the fear out of interFEARence
Taking the fear out of interFEARence
Mobile network interference can be very, very SCARY indeed. Not just on Halloween. Like a ghost, it’s invisible. You don’t know where it’s coming from, nor when it’ll show up. When it manifests, all kinds of things can go haywire. Your cell site starts acting erratically and starts dropping calls. Data throughput takes a dive. […]

What is Tropospheric Ducting?
How the weather can cause interference for mobile networks In 1943, the United States Army built Kagnew Station in Eritrea, Africa. Disguised as a telephone relay station and equipped with satellite dishes and antenna farms, its true purpose was to serve as a listening post during the Cold War. The listening post received signals from […]

Freeing Spectrum from Jammers
Freeing Spectrum from Jammers
The practice of jamming cell phone signals is illegal in the United States, but that does not mean it does not exist. Recently, wideband interference from a jammer in a Mexico prison near the border was noticed by multiple US wireless carriers. Unfortunately, while jammers prevent the use of unauthorized phones inside prisons, they create […]
