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.

Collaborative radio access of heterogeneous cloud radio access networks and edge computing networks
2016 IEEE International Conference on Communications Workshops (ICC), 2016Although the technical merits of the heterogeneous cloud radio access networks (H-CRAN) architecture have been well demonstrated in terms of data rate enhancement and ubiquitous wireless service provisioning, solely relying on the H-CRAN may not be sufficient to further support full automation and everything-to-everything (X2X) connection for the next ...

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 Network Emulator for LTE
2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009In this paper we present an LTE RAN (Radio Access Network) Emulator based on a new method for mobile channels modeling. The new method is then used to model the OFDMA Downlink of LTE (Long Term Evolution) link level performance under 16-QAM hierarchical modulation.

On the capacity of cloud radio access networks
2017 IEEE International Symposium on Information Theory (ISIT), 2017Uplink and downlink cloud radio access networks are modeled as two-hop K-user L-relay networks, whereby small base-stations act as relays and are connected to a central processor via orthogonal links of finite capacity. Simplified versions of noisy network coding and distributed decode-forward are used to establish inner bounds on the capacity region ...

Improving restorability in radio access network
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004In the past, wireless network reliability issues have received limited attention. Previously proposed solutions have focused on protection against base station failures, which may require significantly more base stations than necessary. Actual data from wireless carriers suggest that problems in the backhaul are the uttermost reliability problems faced,

Radio Access Network Slicing in 5G
2017Network slicing is one of the key technologies for 5th-Generation (5G). It enables operators to construct network slices with similar qualities as dedicated stand-alone networks, but to realize them on a common physical platform. Meanwhile, the isolation among logical network slices can keep them from the negative impacts of other network slices.

Virtualization and Orchestration of Radio Access Network
2018 IEEE International Conference on Communication Systems (ICCS), 2018This paper discusses orchestration of RAN systems implemented with virtualization. The 5G mobile communication system should have one flexible network structure that can accommodate a wide variety of services in multiple industries. This paper presents the design and implementation results of a flexible RAN system with NFV reference model.

5G and Radio Access Network architecture
2017 14th International Conference on Telecommunications (ConTEL), 2017Radio access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Current Radio Access Network architecture is undergoing a transformation to increase deployment flexibility and network dynamicity, so that networks will be able to meet the performance requirements demanded by ...
