本文研究了将数字RoF用于LTE-Advanced和超越系统的机会。它表明DRoF是需要基站之间的高度信息交换和协调的几个LTE-Advanced功能的使能者。它还可以降低网络部署成本，增加节能。然而，这意味着几个挑战，例如存在能够定义不同基站组件与光纤之间的连接的标准。此外，载波聚合和增强型MIMO的使用增加了D-RoF支持的比特率，这对于光纤可用性可能是至关重要的。
This paper investigates the opportunities of using the Digital-RoF for LTE-Advanced and beyond systems. It shows that the DRoF is an enabler of several LTE-Advanced features that need high information exchanges and coordination between base stations. It can also reduce the network deployment costs and increase the energy saving. However, this implies several challenges such as the existence of standards able to define connections between different base station components with the fiber. Besides, the use of carrier aggregation and the enhanced MIMO increases the bit rate supported by the D-RoF which could be critical for the fiber availability.
