Abstract:

LTE of mobile communications has been fully opened.In the stage of LTE,BBU’s centralized deployment can effectively reduce the difficulty of development for base station sites,lower down CAPEX/OPEX and achieve rapid network construction,thus rendering large-scale application of the situation.Firstly,the requirement of CPRI link for BBU centralized deployment was introduced.Secondly,several possible solutions for carrying CPRI link were described.Finally,the application recommendations through comparison and analysis were presented.

Key words: common public radio interface, centralized BBU deployment, wavelength division multiplexing
