The $T%&'00 developed *y Huawei is an indoor macro$T%. The $T%&'00 mainly consists o+ the $$ and -)s.
Compared with traditional $T%s, the $T%&'00 +eatures
simpler structure and higher integration
#n this slide, we will mainly introduce the hardware
system structure, application scenarios, *asic +unctions o+
modules, networing mode and typical con/guration o+
the $T%&'00.
