New software-defined open network concepts are proposed in this paper to enable an efficient implementation of front- and backhaul solutions for future 5G mobile networks. Main requirements for 5G front- and backhaul are derived and then related to the open network architecture enabling multiple operators to share the same physical infrastructure. The value(More)
The new Xilinx Early-Access Partial-Reconfiguration (EAPR) FPGA technology exhibits a clear advantage over the former modular-based partial-reconfiguration flow. This paper compares a Handel-C implementation of the two approaches, demonstrating the limitations of the old method, which are fully addressed by the EAPR. It is argued here that the combination(More)
This paper presents an innovative high-bandwidth access network architecture that offers transparent transport services for fixed (≥ 1 Gbps) and mobile applications (LTE and beyond). The main novelty is the development of a high-functionality, low-energy active remote node (ARN) offering high-speed switching and statistical-multiplexing features for(More)
modulation techniques is shown. It is also demonstrated that when SCM is combined with dense wavelength-division multiplexing (WDM), aggregate data capacity of 200 Gb/s is feasible. Preliminary results demonstrate the possibility of 20-GHz WDM channel spacings, which if scaled show the potential for 1-Tb/s aggregate rates with a bandwidth-length product of(More)
This paper reports the results of the proof-of-concept developed to demonstrate the centralized full transmission impairment compensation between the central office and the user's premises in long-reach passive optical networks (LR-PONs). The impairment compensation technique uses the information from a broadband channel sounding performed by only nine(More)
Terrestrial Trunked Radio (TETRA) technology ("Airwave") has led to public concern because of its potential interference with electrical activity in the brain. The present study is the first to examine whether acute exposure to a TETRA base station signal has an impact on cognitive functioning and physiological responses. Participants were exposed to a 420(More)
With the recent increase of the number of Fiber-to-the-Home deployments worldwide, and the corresponding huge investment in infrastructure, there is a need to devise a migration path that assures the full future usability and enhanced performance of the installed fiber plant, possibly using emerging opto-electronic technologies. With this aim, within the(More)
