The traffic in optical and mobile networks has been rapidly increasing. The peak rate of 5G mobile networks will be comparable to that of FTTH. In this paper, we will discuss integrated optical and wireless technologies for mobile front-haul networks towards 5G era and beyond.
The peak rate of coming 5 G mobile services will be comparable to that of FTTH. In this paper, we will discuss integrated optical and wireless technologies, such as RoF, for efficient use of bandwidth of future mobile back/front-haul networks towards beyond 5G era.
Network architecture and transmission technologies to increase an overall efficiency in transport networks are discussed. Traffic grooming in a flexible grid with rate-tunable transponders by optical OFDM is an attractive solution.
Optical network technologies from access to core for fixed and mobile broadband services are reviewed. Manageable all optical network and resource management for end-to-end QoS are also presented for advanced high-quality network services.
A path computation-capable network management system (NMS) which enables to manage topology and physical impairments, and create GMPLS-based lightpaths according to path computation results. Control and management capabilities have been evaluated using all-optical network testbed.
