Revolutionary Spectrum Analytics

Spectrum-NET Mobile operators invest billions of dollars into spectrum licenses, RAN equipment, network optimizations and advanced technologies to ensure maximum spectral efficiencies. Despite these massive investments, mobile operators today lack visibility to the amount and effect of external and unintended internal RF interference within their networks. External interference originates from outside the mobile operator deployed networks; sources could include networks in bordering geographies, emissions from industrial equipment, unauthorized devices, and unauthorized nodes. Unintended internal RF interference originates from within the mobile operator deployed network but is not expected and is unaccounted for during typical network optimizations; sources could include faulty equipment at a tower site (e.g. causing PIM), rogue UEs, and distant cells within the operator network via tropospheric ducting. No mobile operator would think twice about protecting their offices with qualified security personnel, yet their most valued asset, licensed spectrum, remains unguarded - until now. Looking forward, the capability to measure, isolate and quantify external RF interference will become even more essential for mobile operators as spectrum sharing becomes a reality (among operators and with the government) with the evolution to 5G.

Protected by twenty-two patents and patent applications, Spectrum Effect’s groundbreaking spectrum analytics solution, Spectrum-NET, automatically detects, characterizes, locates and assesses the impact of external and unintended internal RF interference. Examples of the interference detected by Spectrum-NET and possible causes are listed in the following table. Spectrum-NET determines the characteristics of the RF interference such as bandwidth (narrow-band or wide-band) and periodicity (persistent, periodic or random repetitive).

Interference OriginInterference LocationExamplePossible Cause
Internal On-site PIM Interferer Rusty Connector or ground strap
Internal On-site Powered interferer Noisy switching power supply, faulty site electronics, HVAC, etc.
External Off-site Industrial Noise Industrial machine with worn motor brushes, arcing power line insulators, faulty power line lightning arrestors…
External Off-site Unauthorized or illegal carrier Gray market device licensed for other countries.
Internal Off-site Rogue UE Malfunctioning UE
External Off-site/Distant External network Cross border/market boundary interference
External Off-site SAS channel monitoring CBRS, LSA sharing programs


Spectrum-NET operates throughout multi-vendor UMTS and LTE networks on a continual basis without interruption to service and with no dependency on external probes. The Spectrum-NET advanced Machine-Learning framework and state of the art algorithms address an extensive set of RF interference types. Spectrum-NET is a web-based, cloud-ready, highly scalable solution with extensive mapping, visualization and report generation capabilities. Looking forward, the capability to measure, isolate and quantify external RF interference will become even more essential for mobile operators as spectrum sharing becomes a reality (among operators and with the government) with the evolution to 5G.
