Дослідження мобільної мережі нового покоління на основі NG-PON2 технології

Abstract

A study of the peculiarities of building high-speed wireless networks, in particular, the architecture of a convergent access network based on NG-PON2. Taking into account the structures of base stations of mobile networks, the modernization of the architecture of modern wireless networks based on PON2 was performed. The study of the topology of the mobile network based on LTE technology is performed and the structure of the linear path of the radio access network is considered in detail. A block diagram of the process of forming a CPRI signal from a radio signal and a block diagram of the functional distribution of RRH / BBU in the upward direction of the radio access network are proposed. When developing the WDM-PON-based access network architecture, a simplified WDM-PON architecture was obtained from AMCC to support MFH. The simulation model of FOTS is offered and investigated.
