BTS3900A
La BTS3900A está formada por dos gabinetes apilables (el gabinete APM30 o APM30H y el gabinete de RF de exterior). Además, la BTS3900A se puede configurar con el gabinete de transmisión (opcional) y el gabinete de batería (opcional). Por lo tanto, con sus diferentes configuraciones, la BTS3900A es aplicable a los escenarios de exterior, tales como instalación centralizada o reubicación de las BTS macro de exterior, tal como se muestra en la Figura 3-9. La configuración se describe a continuación:
La BBU3900 y los equipos de transmisión se instalan en la APM30 o APM30H. La CRFU está instalada en el gabinete RF.
La APM30 o APM30H proporciona espacio para la instalación y la protección exterior para la BBU3900, suministra energía ¨C48 V CD a la BBU3900 y CRFU, y ofrece otras funciones como gestión de batería, monitoreo y protección contra descargas.
Un gabinete de RF puede albergar un máximo de seis CRFU.
Soporta entrada monofásica de 220 V CA, entrada trifásica de 220 V CA , entrada con tensión doble de 110 V CA, y ¨V CD C48.
La BTS3900A, uno de los más compactos gabinetes de BTS de exterior en la industria de las telecomunicaciones, es liviana y fácil de transportar debido a su diseño apilable.
