Rilevamento delle interferenze

Individuare ed eliminare tutti i tipi di interferenza

I trasmettitori indesiderati sono presenti ovunque nelle odierne reti mobili, e possono degradare la capacità della rete e ridurre la qualità dell’esperienza (QoE) percepita dai clienti. Con la densificazione delle celle e la messa in esercizio di standard emergenti con modulazione di ordine superiore rispetto alle tecnologie precedenti, l’ambiente RF diventa sempre più complesso, rendendo le reti sempre più suscettibili alle interferenze. Pertanto, il rilevamento delle interferenze è un problema fondamentale per gli operatori di reti mobili e le autorità di regolamentazione.

Le interferenze esterne possono provenire da un trasmettitore radio con o senza licenza. Qualche dB di riduzione del rapporto segnale/rumore al ricevitore ha un impatto drastico sulla capacità della rete, con conseguente perdita di ricavi e di QoE degli abbonati, il che impone agli operatori di rilevare rapidamente le interferenze per porvi rimedio.

Fortunatamente, gli scanner possono identificare automaticamente i trasmettitori indesiderati, mentre gli analizzatori di spettro o i ricevitori di misura, insieme a un’antenna radiogoniometrica abbinata a un sofisticato software di misura, possono automatizzare il processo di localizzazione della sorgente interferente.

Combinando decenni di esperienza nel settore con una tecnologia all’avanguardia adatta ad ogni budget e caso d’uso, le soluzioni di Rohde & Schwarz per il rilevamento delle interferenze consentono agli operatori di rete, alle autorità di regolamentazione e alle società di servizi di identificare e localizzare qualsiasi fonte di interferenza RF nelle reti mobili in modo rapido ed efficiente.

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.

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.
