Migration of Existing Access Networks Towards Multi-Radio Access
IEEE Vehicular Technology Conference, 2006Integration of heterogeneous access technologies to provide multi-radio access allows for dynamic access selection. The "always best connected" paradigm can increase system capacity and end user throughput, as well as, reduce the network deployment costs for multi-radio wireless networks.

Radio Access Network Evolution
2017Today, mobile network operators have a variety of options for the means of providing more coverage, capacity, and services to their subscribers. Alongside the advancement of wireless standards to provide higher spectral efficiency, vendors have released a wide range of radio access nodes for network densification.

Photonics for radio access networks
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017In this work we analyse radio access networks (RAN) deployments from the capacity and cost points of view. We find that in order to support the new radio (NR) with system bandwidth of 800MHz and reduce the number of fibre connections between NR and baseband units (BBU) one can use dense wavelength division multiplexing (DWDM), pulse amplitude ...

Proceedings of 1994 International Conference on Personal Wireless Communications, 2002
Presently, there is an increasing interest in radio access as an alternative to other access technologies, because the existing radio technologies for fixed and mobile subscribers, might have advantages that make them superior to solutions based an wires for certain applications.

Radio virtualization and cloud signal processing are new approaches to building cellular Radio Access Networks (RAN) that are starting to be deployed within the cellular industry. For cellular operators, Cloud RAN architectures that centrally define or decode transmissions, placing most of the base-station software stack within a data-centre, promise ...

Authorization for Access in Fog Radio Access Networks
2021 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2021As a novel networking paradigm, Fog radio access networks (F-RANs) have gained great attention due to the advantages such as multiple transmission modes, interference prevention, and edge caching. But security guarantee in F-RANs is a vital problem where illegal users may access to F-RANs without proper authorization.

Broadband fibre-radio access networks
International Topical Meeting on Microwave Photonics. Technical Digest (including High Speed Photonics Components Workshop) (Cat. No.98EX181), 2002The paper will discuss architectures for providing broadband wireless access using optical fibre signal transport systems. Recent advances in microwave modulated optical signal generation using optical phase lock loops and fibre grating lasers and in signal detection using optically controlled heterostructure phototransistors will also be described.

Radio Access Network sharing in cellular networks
2013 21st IEEE International Conference on Network Protocols (ICNP), 2013Mobile operators are witnessing a dramatic increase in traffic spurred by a combination of popularity of smartphones, innovative applications and diverse services. As mobile traffic transitions from being voice dominated to video and data dominated, the revenue per byte for the mobile operators is declining at an unhealthy rate.

Radio access technology classification for cognitive radio networks
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013In spectrum bands where spectrum sharing is allowed by national regulators, radio access technology recognition is an important technique for reducing interference and facilitating cooperation among cognitive radios. Unlicensed users (secondaries) need to be able to differentiate between transmissions of licensed users (primaries) and other unlicensed ...
