For the incoming 5G mobile communications, enhanced cell coordination is deemed as crucial to maximize network throughput. In this paper we focus on the impact that the placement of coordination controllers in the metro optical network has on the performance of cell coordination, and we aim at verifying how throughput maximization can be achieved through optimized controller placement. Specifically,...
5G Radio Access Networks (RANs) are supposed to increase their capacity by 1000x to handle growing number of connected devices and increasing data rates. The concept of cloud-RAN (CRAN) has been recently proposed to decouple digital units (DUs) and radio units (RUs) of base stations (BSs), and centralize DUs into central offices. CRAN can ease the implementation of advanced radio coordination techniques,...
Passive Optical Networks (PONs) are a promising candidate to solve the last-mile problem in access networks. By using optical fibers, PONs can offer to the subscribers higher capacity than other traditional access technologies, such as xDSL or Cable-TV, at a lower cost than FTTx solutions. As for any other access-network technology, security is a very important issue. PONs have very specific security...
