The switch-mode power supply converts incoming AC voltage into DC voltage and supplies all of the components integrated in the radio base station. Blackouts and voltage drops in the grid are bypassed due to an integrated supply management concept using alternative sources of electricity, such as batteries, photovoltaic units or generators. Ongoing operations are therefore maintained, even in an emergency. Actually in the event of extreme ambient temperatures, only minimal power losses occur.
In critical network systems such as the radio base station, optimum power distribution is a key element in managing power capacities. Intelligent power distribution means that peak loads are balanced out and power consumption is monitored. The particular challenge here is high performance transmission at the same time within a tight installation situation on the component front.
Environmental conditions such as temperature fluctuations and water penetration can cause extensive damage. To prevent this, the sensors' ambient statuses are ascertained and forwarded to a control system in the radio base station for evaluation. The monitored aspects include for example, battery condition, door status and humidity in the control cabinet. When it comes to this sensitive information, precise transmission of what are often analogue signals, is extremely important.
Reliable transmission of high-frequency data is a basic requirement for radio infrastructure. Applications such as mobile internet and ever-growing data rates call for individual components to be of a high quality. Secure connectivity is indispensable for optimum data wiring within a radio cell. Conventional interface solutions often lead to voice and data losses due to inadequate shielding. In addition, the speed required cannot be achieved due to transmission properties being too low.
High humidity and fluctuating temperatures due to waste heat or solar radiation can limit the performance and service life of electronic components. In particular, increased humidity can cause component corrosion, creeping currents and an increased risk of short-circuiting in the control cabinet. Complying with set temperature and humidity values within a small tolerance range is a considerable challenge. Fan systems or even heating and air-conditioning systems protect the sensitive components in radio base stations.

En el mundo tan interconectado en el que vivimos, las estaciones base de radio se encargan de la importante tarea de procesar el funcionamiento de las radios móviles. Estos dispositivos instalados garantizan una transmisión de voz y datos óptima, así como una disponibilidad completa. La estación base debe garantizar que las señales de radio móviles se envíen, se reciban, se cifren y se amplifiquen de forma fiable, incluso en condiciones meteorológicas adversas. Asimismo, debe poderse ampliar a través de diferentes componentes de dispositivos para mantenerse actualizada con respecto a los continuos avances en tecnología de radio móvil. El aumento en el número de usuarios y los volúmenes de datos, cada vez mayores, hacen que las necesidades sean más exigentes que nunca.
