Abstract: Abstract One of the main challenges in today’s access networks for 5G base stations (BSs) is the final links (or the last mile) of the network. The links that constitute the main backbone of the network are mostly based on Internet Protocol (IP)/Multi-protocol Label Switching networks with connection over fiber cables. However on the access network side, Mobile Network Operators (MNOs) may also benefit from existing copper lines in addition to fiber and microwave lines. Therefore, developing a 5G deployment strategy to connect BSs that are installed indoor and outdoor locations with these different connection types to the backhaul network, will be important to ensure cost-effective installations. Utilizing Fiber-to-the-x (FTTx) networks that are already installed for broadband connectivity will provide MNOs significant initial investment benefits. In this paper, we have analyzed 5G readiness of the backhaul links of a real infrastructure provider using the proposed evaluation methodology. Our large-scale experimental analysis identifies the problematic sites (where possible solutions and suggestions are also proposed) and determines the suitability of the copper circuits for services that can be provided over the next generation networks. At the end of the paper, we also discuss about the challenges and advantages of utilizing different 5G services when FTTx is used as a backhaul and propose an ordering of the measurable FTTx specific quality parameters according to next generation service deployment scenarios.
