With the acceleration of digital village construction

rural 5 G network construction is imminent. Taking "basically realizing the same coverage level as GSM voice

ensuring the capacity demand of some hot areas

taking into account the investment cost and benefi t" as the rural 5 G network construction goal

this paper comprehensively evaluates the performance and cost of each frequency band

and puts forward the rural 5 G multi frequency cooperative network construction strategy with 700 MHz as the wide coverage basic frequency band and 2.6 GHz as the capacity supplementary frequency band

At the same time

combined with the current 2 G/4 G situation of the current network

the 700 MHz wide coverage construction scheme based on GSM900 MHz station site and the accurate adaptation scheme of 2.6 GHz capacity by scene and station based on 4 G service are given.
