What is a distributed base station?

Analysis: The distributed base station is a new generation of modern products used to complete network coverage. Its main feature is to separate the radio frequency processing unit and the baseband processing unit of the traditional macro base station and connect them through optical fiber.

Advantages: Distributed base stations have the advantages of low cost, strong environmental adaptability, and convenient construction. Especially in future 3G mobile networks, distributed base stations will be widely used.

Distributed base station concept:

Distributed base station divides traditional macro base station equipment into two functional modules according to functions, including baseband, main control, transmission, clock, etc. The functions are integrated in a module called the baseband unit BBU

(Base Band Unit). The baseband unit is small in size and very flexible in installation location; the transceiver, power amplifier, etc. are integrated in another module called On the remote radio frequency module, the radio frequency unit RRU

(Remote Radio Unit) is installed at the antenna end. The radio frequency unit and the baseband unit are connected through optical fibers to form a new distributed base station solution.
