Migration of Existing Access Networks Towards Multi-Radio Access

IEEE Vehicular Technology Conference, 2006
Integration 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.

Photonics for radio access networks

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
In 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 ...

Blockchain Radio Access Network Beyond 5G

IEEE wireless communications, 2020
We present a blockchain radio access network (B-RAN) as an advanced wireless access paradigm. The proposed B-RAN unites massive trustless subnetworks to form a large-scale trustworthy cooperative network by leveraging the blockchain principle.

Radio in the access network

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.

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 ...
