R&S FPH를 이용한 간섭 탐지

간섭 신호 탐지

모든 종류의 간섭 확인 및 제거

오늘날의 모바일 네트워크에는 통신과 상관없는 송신기가 너무나 많아 네트워크 용량과 가입자 QoE가 감소하고 있습니다. 셀의 밀도는 높아지고 고차 변조를 지원하는 신규 기술 규격이 기존 기술과 더불어 사용되면서 RF 환경은 점점 더 복잡해지고 네트워크는 간섭에 더 취약해지고 있습니다. 따라서 간섭 탐지는 모바일 네트워크 사업자와 규제당국에게 핵심적인 문제입니다.

외부 간섭은 면허대역/비면허대역에 상관없이 모든 무선 송신기에서 발생할 수 있습니다. 신호 수신에서 단 몇 dB의 신호대잡음비의 감소만으로도 네트워크 용량은 크게 감소하고 매출 손실 및 가입자 QoE 저하로 이어질 수 있기 때문에 통신 사업자는 간섭을 신속히 탐지해야 합니다.

스캐너는 통신과 무관한 송신기, 스펙트럼 분석기 또는 수신기를 자동으로 식별할 수 있고 방향 탐지 안테나 및 정교한 소프트웨어와 함께 동작하여 간섭 탐지 과정을 자동화할 수 있습니다.

수십 년간 현장에서 쌓아 온 전문지식을 필요한 예산과 목적에 맞춰 제공하는 로데슈바르즈의 간섭 탐지 솔루션으로 네트워크 사업자, 규제당국 및 서비스 기업은 모바일 네트워크의 모든 RF 간섭 소스를 빠르고 효율적으로 찾아낼 수 있습니다.

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.
