Cloud Radio Access Networks

2013
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), 2021
As 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.

Radio Access Network sharing in cellular networks

2013 21st IEEE International Conference on Network Protocols (ICNP), 2013
Mobile 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), 2013
In 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 ...

Optimizing Access Radio in Multi-Radio Mesh Network

2009 IEEE International Conference on Communications, 2009
This paper discusses a hierarchical multi-radio mesh network, where the normal clients associate with the mesh AP through the access radio and then the mesh APs communicate with each other via the mesh radio. While most of the existing studies focus on the performance issue for the mesh nodes communication with the mesh radio, in this paper, we argue ...

Unified Radio Access Network operation for Multi-Radio Access Technology cellular systems

2014 21st International Conference on Telecommunications (ICT), 2014
The architectural structure of Radio Access Networks (RANs) in Multi-Radio Access Technology (RAT) cellular systems is based on the independent iteration of single RAT RANs and statically dividing radio frequency resources between co-deployed RATs, leading to high system complexity and suboptimal spectrum utilization.
