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.
