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.

Las mediciones de reflexión son un método habitual para evaluar el rendimiento en sistemas de antenas. Cuando se refleja una cantidad mínima de la señal transmitida, indica que la energía de transmisión puede alcanzar la cobertura deseada. La alta reflexión no deseada ocasiona que el sistema sea ineficiente y puede dañar sus componentes. Las mediciones de reflexión pueden expresarse en términos de pérdida de retorno, VSWR y coeficiente de reflexión.
