ISCO’s active solutions do more than monitor, they adaptively improve signal quality and network performance.

ISCO Helps Wireless Networks Work Better And Carry More Traffic

ISCO delivers software-based solutions to wireless network operators that improve spectral efficiency and immediately increase the amount of traffic wireless networks can carry.

ISCO solutions are RF conditioning Network Functions operating on a variety of ISCO hardware platforms.  These multiple hardware platforms offer flexible integration options for DAS, macro cell sites, small cells, CPRI and C-RAN configurations.

ISCO solutions are active and in line, doing more than just monitoring. Many solutions today only monitor performance. ISCO solutions take action to do more. ISCO monitors the condition of the wireless links, analyzes the signal, and takes action to improve network performance.

Beyond ISCO's platforms, ISCO’s patented modular software technology can be embedded in other network devices, OSS, and Self Optimizing Network (SON) applications.  By virtualization of the ISCO Network Functions within other network software and infrastructure, service providers can realize the benefits of ISCO spectrum conditioning solutions on a wider scale.

“network Optimization for 5G” paper from mobile experts quantifies total cost of ownership for optimized vs non-optimized networks

5G will bring several new architectural changes along with a new air interface. These include Massive MIMO, Open RAN networks, Virtualization, and Edge Computing. This paper from Mobile Experts examines the level of performance that can be expected in new architectures and how optimization affects the economics of maintaining 5G networks.

The paper describes how seemingly optimal networks can have a cluttered or degraded RF environment, especially due to PIM, non-cellular sources and Inter-cell interference.

A case study shows the trade-off between proprietary and open networks and the impact over time of applying optimization solutions, potentially saving millions of dollars in both CAPEX and OPEX.

RCR Wireless Report Issued August 2017

RCR Wireless Report Issued August 2017

new report from RCR Wireless "Spectrum monitoring, testing and analysis" features insight from ISCO international and other spectrum experts

The radio environment is getting ever more complex and crowded, as new technologies, new devices and new spectrum bands come into play.  Meanwhile, dynamic spectrum sharing is becoming the new paradigm for policy as regulators seek to promote more efficient use of scarce spectrum resources.

Advanced cellular technologies are more dependent than ever on clear channels in order to produce the gains in efficiency and performance that operators desire, but adding billions of new internet of things devices may raise the noise floor.  All of this adds up to challenges in system design and the need for better, faster, cheaper and easier ways to understand the RF environment, locate and address sources of interference.

This new report from RCR Wireless looks at factors impacting interference in wireless networks, strategies for dealing with interference and how the roles of industry and government are shifting. You will learn:  

  • Current approaches and developments in spectrum interference detection and monitoring
  • Industry trends that are impacting the need for spectrum monitoring as well as technical challenges  

Wireless Operators Face Numerous Challenges

The amount of data wireless networks carry is doubling every year and expected to reach over 6.4 Exabytes per month by 2021 in North America alone.  Under continuous competitive pressure to lower subscriber prices while meeting financial objectives, wireless service providers need to improve spectral efficiency to get the most out of their spectrum.  By conditioning the RF link and automatically optimizing the network, service providers can provide better subscriber experience, lower the cost to deliver service and improve the gross margin of their services. 


Macro Cells & Dense Urban

Dense urban areas with high traffic volumes pose many challenges for wireless service providers.  Finite spectrum, high costs and long time required to add more cells apply significant pressure. Add to that the high levels of RF pollution, intercell interference and even PIM combined with high densities of subscribers and focused peak demands and the challenge to meet subscriber needs is very real.

Events &

Managing noise rise and optimizing performance real-time are challenges for Venues supporting special events.  Continuously, proactively conditioning the RF links is a proven method to manage noise rise for DAS systems to maintain optimal subscriber experience and network capacity in these very challenging environments.

Centralized RAN & Small Cells

For many reasons, the deployment of small cells and centralized RAN are increasing.  Small cells, increased numbers of RRUs and C-RAN create new challenges for wireless service providers including managing ICI, cell edge performance and ensuring fronthaul integrity across the CPRI links.  

Virtualized Networks

The billions of CAPEX dollars that have been spent over the past 20 years is at the onset of happening again as operators push to new architectures.  5G, densification, IoT, M2M and the many new applications that will become enabled by the future low latency broadband wireless networks will operate from centralized and virtualized architectures.  With the growing deployment of Centralized RAN, this evolution is already starting today.



The uplink needs to operate in adverse conditions including unpredictable high power co-channel and adjacent channel interference which change all the time based on traffic demands and environmental factors.  ISCO’s solutions deliver sophisticated software to evaluate the complicated spectral environment and improve the condition of the signal.  ISCO’s RF conditioning Network Functions have shown a positive impact on many aspects of the wireless network as measured by operator key performance indicators (KPIs), including SINR, RSSI, CQI, downlink throughput, connected users, and data volume. 

Adaptive Interference Mitigation

Adaptive Interference Mitigation

PurePass® Interference Mitigation

The foundation of ISCO's family of RF performance network functions, PurePass® targets a wide variety of in-band and out-of-band interference scenarios with high performance digital filtering. PurePass® Adaptive Interference Mitigation (AIM) algorithms provide dynamic and autonomous, highly selective in-band filtering that mitigates a wide variety of external interference sources impacting the uplink signal, restoring performance. In addition, PurePass User-Defined Band Reject (UBR) filtering can be used by RF performance engineers to protect against a wide variety of impairments.

Spectrum Visibility and Analytics

Spectrum Monitor Visibility and Analytics

Engineers working with today's complex networks know the limitations that come from lack of visibility into what is happening in the RF that can impact network performance. ISCO's Spectrum Monitor brings real-time visibility across all of the RF paths where ISCO's solutions are deployed. This multi-sector capability combined with detailed interference analytic tools of ISCO's SpectrumInsight ProTools put powerful tools in the hands of RF performance engineers to quickly and effectively identify RF issues and respond accordingly.
