Lost Capacity of the UMTS Radio Access Network

Wireless Personal Communications, 2006
The theoretical capacity models for the downlink and the uplink of the UMTS radio access network have been researched ever since the UMTS started to be considered. However, they were often based on idealistic assumptions and addressed a static situation. Because of that results were too optimistic.

Network coverage expansion in radio access network sharing

2017 Sixth International Conference on Future Generation Communication Technologies (FGCT), 2017
The frequency resource is limited due to multiple operators and various services. It is important to reduce intra- operator interference with multiple operators that are occupied same frequency band. Sharing radio access network technology is one of promising solution for intra-operator interference.

Open Wireless Network Architecture in Radio Access Network

2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013
Continuous evolution of wireless protocol and the increasing unmanaged deployment of small cells (e.g. Pico-cell, femto-cell or Wi-Fi APs) have raised an urgent need to update mobile network architecture. To support such evolvability, we design the Open Wireless Network (OWN), a novel evolved architecture for radio access networks, including UMTS, 802 ...

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.

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 ...
