FIELD: communication facilities.
SUBSTANCE: invention concerns communication systems. Base band unit (BBD) and radio frequency unit (RFU) of base station are separated in the system, and RFU is equipped with radio frequency interfaces of base band for interconnection of BBU and data transfer, this forming base station. By separation of BBU from RFU, further simultaneous division of BBU bandwidth takes place, and each unit is arranged independently. BBU networking and BBU bandwidth increment can be maintained by bandwidth increment interfaces and radio frequency interfaces of base band implemented by interface units of BBU by flexible and convenient methods.
EFFECT: reduced operational cost.
