Crucial for proper operation of mobile networks. Part 4 of the series on Cable and Antenna verification
Critical Infrastructure: Mobile base stations rely on a complex interplay of components, including often-overlooked elements like filter combiners, RF splitters and tappers, and cables, to deliver uninterrupted mobile communications.Vulnerability to Environmental Factors: Filter combiners, accessories, and cabling in mobile base stations are susceptible to harsh environmental stressors, which can lead to signal degradation and reduced system availability.Fundamental Properties: The functional integrity of mobile base station components is measured against key RF parameters, including frequency response and insertion loss, to ensure conformance to manufacturer and industry standards (e.g., 3GPP, ETSI).Measurement Techniques: Systematic and comprehensive testing is essential to validate the functional integrity of critical mobile base station components, detect latent defects, and optimize overall system performance.

Crucial for proper operation of mobile networks - Part 3 of the series on Cable and Antenna verification
Key points: Critical Infrastructure: Leaky feeder systems are a crucial, yet costly to modify, element of in-building and tunnel infrastructure for mobile communication coverage.Vulnerability to Environmental Factors: The leaky feeder system's exposure to high humidity, extreme temperatures, and physical stress makes it prone to water ingress, corrosion, mechanical damage, and material degradation.Fundamental Properties: Changes in a leaky feeder system's characteristic impedance cause reflections of forward RF energy, resulting in discontinuities, which can occur at connectors, kinks, or compressions in the cable.Measurement Techniques: Due to practical limitations, leaky feeder system testing typically involves measuring insertion and return loss, supplemented by evaluating key performance indicators (KPIs) and user equipment reports to assess actual coverage and identify potential defects.

반사 측정은 안테나 시스템 성능을 평가하는 일반적인 방법입니다. 최소량의 전송 신호가 반사된 경우 전송 에너지가 의도된 커버리지에 도달할 수 있음을 나타냅니다. 높은 반사는 시스템을 비효율적으로 만들고, 부품을 손상시킬 수 있습니다. 반사 측정은 반사 손실, VSWR, 반사 계수로 표현할 수 있습니다.
