Chasse aux interférences avec le R&S FPH la nuit

Chasse aux interférences

Localisez et éliminez tous les types d'interférences

Les émetteurs indésirables sont omniprésents au sein des réseaux mobiles d'aujourd'hui, dégradant la capacité du réseau et réduisant la QoE des abonnés. Avec la densification des cellules et le déploiement des nouvelles normes avec une modulation d'ordre supérieur relative aux technologies existantes, l'environnement RF devient de plus en plus complexe, rendant les réseaux plus sensibles aux interférences, donc la chasse aux interférences est primordiale pour les opérateurs et les régulateurs de réseaux mobiles.

Des interférences externes peuvent provenir d'un émetteur radio licencié ou non licencié. Une diminution de quelques dB dans un rapport signal / bruit au niveau du récepteur impacte de manière importante la capacité du réseau, avec des pertes de revenus conséquentes et relatives à la QoE des abonnés, nécessitant que les opérateurs réduisent rapidement les interférences.

Heureusement, les scanners peuvent identifier automatiquement les émetteurs et les analyseurs de spectre ou les récepteurs indésirables, associés à une antenne directionnelle et un logiciel sophistiqué, permettant d'automatiser le processus de localisation des interférences.

En combinant des décennies d'expertise sur le terrain avec une technologie de pointe pour tous les budgets et tous les cas d'utilisation, les solutions Rohde & Schwarz dédiées à la chasse aux interférences permettent aux opérateurs réseau, aux régulateurs, ainsi qu'aux entreprises de service d'identifier et de localiser rapidement et de manière efficace toutes les sources d'interférences RF au sein des réseaux mobiles.

Webinar: Prepare your spectrum for 5G deployment

The roll out of 5G NR will initiate a worldwide deployment in an unknown radio environment where unwanted transmitters can degrade end user QoE and in some cases cause outages of critical services. Prior to deployment, operators need to ensure the radio environment is free from interference by conducting spectral clearance and interference hunting. This webinar defines the particular challenges of 5G NR, highlights a robust approach to prepare the spectrum and shares real field data at 3.5 GHz and 28 GHz.

Webinar: Identifying and eliminating interference in mobile networks

Interference in the Radio Access Network is ubiquitous and becoming more critical as the deployment of the latest cellular standards bring increased sensitivity and subsequent degradation of network performance. This webinar examines the different sources of interference in mobile networks and considers their impact on capacity and subscriber Quality of Experience.

Using FPH Gated Trigger Settings For a Live 5G Signal

Video: Using FPH Gated Trigger Settings For a Live 5G Signal

For TDD networks, the downlink and uplink signal share the same frequency band. They are divided by time (using different time slots). When using an analyser in frequency mode, the downlink would mask any uplink activities, being the dominant signal. Hence it is quite difficult (if not impossible) to see any uplink signals and possible interference sources. With R&S®Spectrum Rider FPH or R&S®Cable Rider ZPH (v.12 model with ZPH-K1 option) gated trigger feature, it is possible to mask out the downlink signal and focus on the uplink activities.

Brochure: Interference hunting

With 5G and other wireless services new signal types with more complex modulations increasingly occupy the spectrum. This increases the risk of interference and makes it more difficult to mitigate. However, advanced equipment from Rohde & Schwarz significantly facilitates the interference hunting process.

Application card: Interference hunting in smart factories

Smart factories rely heavily on wireless communications technology to automate production processes and increase productivity. RF interferer signals can be generated intentionally or unintentionally, appear at any time, be located anywhere on the production floor and can disrupt the production process or delay the output. This application card describes the process for determining the location of interferers so they can be eliminated.
