Spectrum pooling allows multiple operators, or tenants, to share the same frequency bands. This work studies the optimization of spectrum pooling for the downlink of a multi-tenant Cloud Radio Access Network (C-RAN) system in the presence of inter-tenant privacy constraints. The spectrum available for downlink transmission is partitioned into private and shared subbands, and the participating o...

In an attempt to optimize network performance of delivered 2G and 3G services and reduce operating costs, today's mobile operators are searching for aggregation and concentration alternatives for the backhaul network. This paper explores a solution that would provide improved traffic aggregation at the regional hub sites in order to optimize traffic backhauling to the network core.

This paper presents a comprehensive model including wireless backhaul as cost-effective alternative to wired for vehicular networks, heterogeneous underlay cognitive network with multiple mobile secondary transmitters acting small cells, mob

The 5G wireless network architecture will bring dense deployments of base stations called small cells for both outdoors and indoors traffic. The feasibility of their dense deployments depends on the existence of a high data-rate transport network that can provide high-data backhaul from an aggregation node where data traffic originates and terminates, to every such small cell. Due to the limite...

With the increasing densification of 5G and future 6G networks high-capacity backhaul links to connect numerous base stations become an issue. Since not all can be connected via fibre for either technical or economic reasons wireless connections at 300GHz, which may provide data rates comparable links, are alternative. This paper deals with planning 300GHz describes two novel automatic approach...
