BTS3900
La BTS3900 es aplicable a los escenarios de interior, como instalación centralizada y reubicación de las BTS macro, tal como se muestra en la Figura 1-1.
La BTS3900 soporta la entrada de corriente directa C48 V CD y los modulos correspondientes. Los módulos de la BBU3900 y la CRFU se instalan de manera centralizada en un gabinete de interior. Como la BTS macro de interior más compacta de la industria, la BTS3900 es liviana, pequeña, posee gran capacidad y una buena extensibilidad.
Además, las BTS3900 se pueden apilar y combinar para ahorrar espacio, tal como se muestra en la Figura 1-2.
