What are the advantages and disadvantages of distributed pico-flying base stations?

1, distributed pico-flying base station, which is convenient to build, easier to coordinate, more accurate in power control, good in coverage effect, and convenient to maintain. The software sets cell merger or division, which is convenient for expansion.

2. Disadvantages are that equipment manufacturers have different levels of support, and the construction cost is high. Before construction, it is necessary to specify the network standard and frequency band to be supported. The far end is an active device, which needs independent power supply or power supply through five or six types of wires, so it is not suitable for difficult, closed and humid scenes.

Pico-base stations are divided into integrated pico-base stations and extended pico-base stations, as well as single carrier frequency and dual carrier frequency.
