“…With growing demand for mobile connectivity and high speed services, cellular mobile communication is headed toward smaller cells and higher per user bit rates [1]. Smaller cells means closely spaced access points and therefore high overall cost for optical fiber backhaul implementation.…”

In this paper a directive mesh network operating in the 60 GHz unlicensed band is considered for backhaul support for a small cell mobile network in an urban environment and interference between network links is analyzed. It is observed that while non-line-of-sight stations are adequately isolated by antenna directivity, interference can affect link performance in links that fall in line with each other, namely, line-of-sight links. Seeing as back-to-back links may occur in the proposed network between stations situated within long straight streets, the resulting interference can cause a decrease in network capacity by preventing simultaneous transmission on links. Here, the use of orthogonal polarizations is proposed as a method for controlling interference in LOS links allowing for simultaneous function of a higher number of links and thus better utilization of channel resources and ultimately achieving higher network throughput.

“…Yet, a directive mesh network operating in the unlicensed millimeter wave band (namely, 60 GHz) can provide all that we are looking for: small cells with short links, high data rate (due to huge available spectrum), low cost (no licensing cost), and robust implementation (small antennas with high gain). Over all, free spectrum licensing and elimination of the need for costly trenching and fiber installation along with speedy, robust deployment give the wireless mesh backhaul option a considerable advantage over fiber [5], [6].…”

Because of their exclusive features, millimeter wave directive mesh networks can be considered for small cell backhaul support in urban environments. For this purpose, a network of closely spaced stations has been considered with very directive line-of-sight links operating in the 60-GHz band. An attempt is made to evaluate channel response and interference behavior in such a network, taking into account the effect of building blockage. A simple grid of building blocks is considered as the propagation environment, and wave propagation is simulated using 2.5-dimensional (2.5D) ray tracing (2D with ground effect) to calculate the received signal at different nodes in the network. The results are compared with free space predictions and used to evaluate interference at all nodes in the channel and describe certain characteristics of links, such as the delay profile and the correlation length.

“…This increase in video streaming has directly resulted in a 43% increase in average data usage per month in 2015 [12]. This is predicted to further tax the backhaul networks due to the increased levels of traffic [39,65,27].…”

Topology Control for Resource Management in Microwave Backhaul Networks

<p>Microwave backhaul networks are the dominant technology used to connect together access and core networks for their flexibility and cost-effectiveness in deployment. Unfortunately, microwave backhaul networks are susceptible to interference and are statically managed leading to poor Quality of Service (QoS) in the form of high delays and loss as well as being inefficient on energy. The use of Software Defined Networking (SDN) is proposed to address these problems by dynamically managing resources to work around the interference and remove static allocations. Two new algorithms, CUT and OptiCUT were designed to compute an optimal topology, to minimise loss and delay while at the same time reducing power consumption.</p>
