We are the wireless interference experts

 Let's Talk

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.

  • SINR Optimization

  • RF Filtering

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?
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 […]

Find it. Fix it. Move on to the next.
A common way to track performance problems in a wireless network is to report Key Performance Indicators (KPIs) for individual sites or sectors. Problems are prioritized based on severity and impact on users of the network. Our customer invested in a ProteusCPRI Portable to make it easy to tackle the sites on the report. The […]

ISCO’s PIM Calculator helps Mobile Network Operators plan for frequency mixes that harm the uplink
A PIM problem is often not found until after a cell site is up and running, when a performance issue is flagged by severely degraded throughput or other KPIs. By then it can be difficult to identify and solve. ISCO’s PIM Calculator is an easy-to-use online tool that shows the Passive Intermodulation products IM3, IM5, […]

Wideband interference from digital TV? Not anymore.
High levels of wideband interference from digital TV signals caused our customer continuous harm across multiple PRBs. It was unpredictable and changing over time, with power levels above -85dB impacting KPIs. ISCO’s ProteusCPRI with Dynamic Spectrum Recovery (DSR) removed the interference as it appeared and improved KPIs, returning the site to normal operation. Besides digital […]
