Application Scenarios
ZXSDR BS8800 is an integrated base station with single cab- inet
for indoor application.
ZXSDR BS8800 attaches great importance to the project
demand and the flexibility of base station construction. The in-
door macro cell, in particular, takes up less room, supports wall
mount installation, adopts forward routing technology and com-
pletes subrack plugged out maintenance in front of the cabinet.
ZXSDR BS8800 is applicable for the equipment room with less
space available.
ZXSDR BS8800 is low in cost and high in capacity and expan-
sibility. It integrates built-in transmission equipment and supports
IP over Ethernet and IP over TDM transmission.
