Huawei Mini-shelter was developed for easing operators' pressure in site acquisition, meeting operators' requirements for energy saving and flexible expansion. As an innovative installation solution for site equipment, it not only has a large housing capability like traditional shelter, but also adopts independent compartment temperature control method as outdoor cabinet. Because Mini-shelter has few limitations on application scenarios and can satisfy operators' different requirements, it is gaining more and more popularity in modern site.
