Integrated Wireless Backhaul Over Optical Access Networks

Investigation of Performance in Integrated Access and Backhaul Networks

Wireless backhaul allows densification of mobile networks without incurring additional fiber deployment cost. This, in turn, leads to high spatial reuse, which is a significant tool to meet increasing wireless demand in 5G networks. Integrated access and backhaul (IAB), where access and backhaul network share the same standard wireless technology (e.g. 5G new radio (NR) standard), allows intero...

Optimising Internet Access over Satellite Backhaul

Application level protocols such as the Hypertext Transfer protocol (HTTP) and transport layer protocols such as Transmission Control Protocol (TCP) have performance issues on wired networks. These issues are greatly magnified by the particular conditions of satellite systems. For example, a user experiences long delays e.g. during web browsing, due to the impact that the latency of the satelli...

Wireless backhaul in future heterogeneous networks

The reliability of wireless backhaul mesh networks

When planning the structure of a backhaul mesh network for public access, it is common to introduce redundant nodes in the mesh network. These are called redundant, because they do not increase the network capacity under normal operation, due to the shortest-path metric of the routing protocol. Instead, their sole purpose is to increase the network reliability by providing failover links when a...

Wireless Multicast for Cloud Radio Access Network with Heterogeneous Backhaul

Cooperative communication in which multiple basestations (BSs) jointly transmit to mobile users is a major advantage of the cloud radio-access network (C-RAN) architecture. This paper considers the use of wireless multicast for sharing user messages at multiple BSs in the C-RAN backhaul for cooperation purpose. To combat fading and path-loss in the wireless channels to the different BSs, this p...
